In the field of water treatment and purification, there is one very serious problem - any filter material periodically becomes clogged, which means it needs to be replaced or cleaned (regenerated).

In order to minimize costs for cartridges or bulk material, self-cleaning water filters were developed.

Such systems are so far capable of purifying liquid only from mechanical particles. Some industrial models can regenerate the properties of bulk filter materials to a greater extent by washing them under pressure.

This approach significantly increases the service life of the backfill material and the operation of the filter as a whole.

Types of self-cleaning filters

Currently, the range of most companies offering water treatment products includes the following types of self-cleaning filters:

1. With manual washing. Here the manufacturers assume by “ manually washing" both the physical removal of the filter element with its washing outside the housing, and the cleaning procedure without disassembling the housing, and sometimes even without stopping the water supply in the mains (if the pressure for washing is sufficient to ensure that the surface of the filter element is cleaned).
2. With semi-automatic washing system. “Semi-automatic” here consists of manually starting the automatic cleaning process. The cleaning itself can proceed differently, depending on the type of filter element and technical solutions applied by the manufacturer.
3. With automatic flushing. The most advanced and, as a result, expensive solutions. Here, the cleaning process can be initiated without human intervention, for example, if a contamination sensor is triggered or a timer simply triggers according to a predetermined schedule (schedule).

The last two types (semi-automatic and automatic) of self-cleaning filters are most often used in main high-load water supplies.

These are productive water treatment and water purification complexes, for example, for servicing large swimming pools, equipping any manufacturing enterprise, connections to the water supply of entire cottage villages, etc.

Self-cleaning filters may differ in the housing material.

They are manufactured:

1. Made of plastic (high or low pressure polypropylene);
2. Made of metal (brass, bronze, steel, etc.).

The following can act as a self-cleaning element:

1. Disc elements that, under pressure, form a monolithic porous structure;
2. A mesh surface made of plastic or metal with a given mesh size;
3. Backfill material, which, under pressure in the same way as the disk version, is compacted, forming a homogeneous material with pores for water.

If we talk about household self-washing filters, then most often discs and meshes are used as the filter element; they are easier to maintain and more durable.

Self-cleaning filters can be equipped with additional equipment.

This is how you can find:

• self-cleaning filter with pressure gauge(it is convenient to monitor the pressure in the system, for example, if it increases relative to the pressure while water consumption continues, this may indicate a blockage, which means it’s time to flush it);
• filter with pressure reducer (additionally protects the water supply system from surges in inlet pressure).

Operating principle and advantages

Let's take a closer look at self-cleaning filters used in everyday life (mesh filters). To properly use such water supply units, you need to know their operating principle.

Let's look at the operation of the self-cleaning mesh filter in order.

During normal operation, water enters the inlet and, passing through a fine mesh in the filter flask, leaves small mechanical particles on its surface.

After some period of time, the accumulated dirt will have to be washed off. To do this, it would be necessary to stop the water supply, unscrew the filter housing, remove the mesh and rinse it under water pressure, then reassemble the system in the reverse order and resume the water supply.

But in the case of a self-cleaning filter, all these procedures are not necessary. It is enough to open a special drain ball valve and the deposit of mechanical particles will be washed away by pressure from the surface of the mesh.

It should be noted that it is first necessary to substitute a container for drained water or organize a special channel for the outflow of liquid from the drain tap into the sewerage system (this can be provided for at the stage of installation of the water supply system).

The advantages can be summarized as follows:

1. Significant savings on plumbing work due to periodic cleaning of the septic tank.
2. Saving maintenance time.
3. Budget savings due to the lack of replaceable cartridges, which quickly become unusable and require mandatory replacement.
4. Possibility of continuous operation of the system even during the washing process (depending on the model).
5. Some manufacturers allow you to change the filter element and achieve the required quality of purification of the incoming water; for example, you can install a mesh for finer purification.

VIDEO INSTRUCTION

Should I buy a Honeywell self-cleaning filter or pay attention to analogues?

The most popular among those who install plumbing systems are products under the Honeywell brand. She earned her popularity thanks to high quality execution of all components, the possibility of replacement individual parts, as well as excellent reliability and service life of the products.

Particular attention should be paid to models with a transparent body, which allows you to visually assess the degree of contamination. As well as devices with additional functionality - Honeywell filters equipped with pressure reducers and pressure gauges.

The only drawback of this product is its high cost.

And here you need to try to find an analogue that satisfies all the same demands for quality and functionality as Honeywell self-cleaning filters.

VIDEO OF HONEYWELL WORK

The following products from the group of self-cleaning household filters are presented on the market:

1. Valtec self-cleaning filter(equipped with two filter meshes, one inside the other; mesh cartridges, like those from Honeywell, can be purchased separately. The disadvantages include the lack of models with pressure reducers and a transparent body).
2. Products of the company TIEMME (Italy). The range includes filters even with a transparent body, but not with pressure reducers.
3. Itap filters are equipped with two pressure gauges - at the inlet and outlet, which is very convenient. If the pressure difference is large, it is immediately obvious that the filter mesh is clogged.
4. The German manufacturer SYR also offers semi-automatic household options. Models available for both cold and hot water.

And this is far from full list Honeywell's competitors in the market.

Of course, each product has its own advantages and disadvantages. But the consumer always votes with rubles.

Wherever you take water from, it will contain various impurities: sand, small stones, as well as waste that is formed as a result of our life activities. If the water contains particles of debris, the pipes will begin to clog and deteriorate, which means that the plumbing will need to be repaired. To prevent such problems, water must be purified using special wash filters.

From this article you will learn:

What is the working principle of a water wash filter?

How to install such a filter

What needs to be done to make the wash filter last longer

What is a water wash filter used for?

Main wash filters are necessary to remove various clogging particles that are suitable for any water temperature. The cleaning result directly depends on the size of the cells in the wash filter.

We think everyone understands how a mesh wash filter works. It consists of:

1. Housings with holes for water inflow and outflow.
2. A filter mesh shaped like a cylinder.

The main disadvantage of using such wash filters is the clogging of the mesh itself. Polluting particles settle on its surface, which becomes slagged over time, and, as a result, water flows poorly. To clean, it is necessary to rinse with water in different directions, and then the debris accumulated after such treatment is removed through a hole with a tap.

There are forward and reverse flush filters. In the first, the water that removes contaminants from the mesh moves in one direction - from top to bottom. Cleaning occurs thanks to the strong pressure of water, which washes away all impurities into the container. Terminates this process after turning the valve lever. The second type of washing filters for cleaning involves the movement of water when removing contaminants from the bottom up.

Washing filters can be simple or complex. The cleaning of those that are simpler is initiated by the user. More complex equipment, as a rule, is equipped with special instruments and can be automated. The devices can display time and pressure, and also independently switch to flushing mode.

We would like to note the filter with backwashing. Its design allows you to clean the mesh without stopping the water purification process. Washing should always be of the highest quality, so manufacturers of cleaning systems also offer devices for:

suction of contaminants;

automatic washing;

manual washing.

Filters can be cleaned within a certain time (using a timer) or according to the readings of a special device that measures pressure. Wash water filters with a pressure gauge are capable of automatically switching to backwash mode if there is significant clogging.

A rinsing filter is used for cold and hot water.

Grids for washing filters are made from:

steel sheet;

woven threads;

polymers.

The durability of mechanical wash filters is influenced by the quality of the mesh itself and the reliability of the entire design for water purification. Reliability depends on the following indicators:

quality of cleaning;

slip coefficient.

Particles can slip through irregular shape, which are sometimes positioned in such a way that the mesh does not hold them. The flushing water filter will not be reliable enough if the angle between the mesh and the flow is straight. As the speed of water movement increases, the resistance of the wash filter mesh increases. This indicator affects the quality of the device used for cleaning.

As the water speed increases, the likelihood of breakthrough increases, and therefore, fewer debris particles fall on the wash filter mesh. To reduce the speed, you can increase the grid area, but this is difficult.

You can use laser punching, then the wash filter will purify the water more effectively. The mesh should prevent the formation of rust, since the filter is necessary to purify water of different temperatures. If there are substances in water that promote the dissolution of metals, the likelihood of corrosion on the mesh increases.

Meshes from of stainless steel often used for both industrial and household wash filters. The polymer mesh is less strong, but particles of debris will not stick to it, which means it is easier to wash, and the device itself will work more efficiently.

How to install a wash water filter

Companies that produce washing water filters describe all stages of their installation in the documents accompanying these devices.

Installing a wash water filter requires compliance with safety regulations when carrying out work related to the installation of main wash water purifiers, as well as hygiene and technical requirements to the filtration system. The wash filter must be installed in a heated room to avoid water freezing. The device is installed with the bulb facing down; the pipeline can be horizontal or vertical. Installation and construction conditions must be observed. In addition, it is very important to pay attention to the direction of water flow (this information can be seen on the filter cover). When installing a device with automatic flushing, it must be connected to the mains.

How to clean a water wash filter

Main flushing flow filter for water has an additional hole (at the bottom of the flask). There is a rotary valve on the lower outlet, which is closed when regular work device. When dirt accumulates in the flask, obstructing the movement of water, the valve must be turned. This increases the flow of water, and the clog goes into the drainage from the mesh and from the bottom of the flask. After the rinsing filter is cleaned, the valve must be turned again and left in this position until a new rinsing is required.

Sometimes an empty bucket is placed under the hole, but more often it is done differently. Nowadays they produce wash filters that can be connected to a hose (for this, the design requires a fitting). From the hose the water goes straight into the sewer. This cleaning scheme makes the process as simple as possible; you just need to turn the valve a couple of times, and the water will flush everything itself.

Important! Often, one or two pressure gauges are included in the design of wash water filters. The dial of this device, located at the top of the filter, is not decorative element. When water passes through the filter, its pressure and pressure decrease slightly. As the grid becomes more dirty, the water pressure at the outlet decreases. The degree of contamination can be determined by the difference in pressure between the inlet and outlet. If this value is more than 0.5 atm, the filter must be washed. This is very important when the flask is opaque and it is unlikely that it will be possible to determine in any other way whether cleaning is needed. However, such a check can also be done experimentally: observe the water pressure in the tap. But this method does not always provide an adequate assessment, since water pressure may change due to the fault of the local water utility.

Washable flow-through main water filters can be self-cleaning, but the mesh may deteriorate during operation. Small particles of debris will accumulate in the device, which over time will lead to the formation of a large number of clogged cells, and the throughput will decrease. In this case, simply turning the valve will not solve the problem.

The most extreme measure in this case is to replace the wash filter. Some manufacturers sell devices along with spare screens. In addition, you can clean the mesh yourself, but it will never return to its original characteristics. There are filters with backwashing; they are not afraid of cell clogging. During direct washing, water moves down along the mesh, and during reverse washing, it flows from inside the mesh to the outside. The water has such pressure that the slag is washed out of the cells, and then removed from the flask through the drain fitting.

The backwash mechanism, which cleans the filter as water moves from inside the mesh to the outside, can be implemented in different ways.

Wash filters mechanical cleaning are different. There are universal models that can be used for hot and cold water, their body is made of brass or bronze. Also, wash filters can be designed for hot or cold water only. In devices for low temperatures The flask is transparent, made of plastic, which allows you to visually determine whether cleaning is required on this moment. The plastic from which filter bowls are made is durable and can withstand pressure up to 16 atm. Models with bowls made of brass are suitable for both hot and cold water.

Important! You need to approach cleaning the wash filter carefully; you need to control this process: open the valve in time and drain the water with the collected dirt. It is possible to make this process carried out completely independently.

And it's real! In fact, you can choose a water rinsing filter model that has an automatic rinsing drive built into it (the filter must be connected to sewer outlet). You just need to set the required interval, and the system will switch to cleaning mode on its own. Power is supplied from the mains or batteries.

You can additionally connect a differential pressure switch. It will measure the difference in water pressure at the inlet and outlet of the wash filter and independently turn on the wash drive when this parameter exceeds a user-specified value.

What you need to know to ensure that the wash filter for mechanical water purification lasts a long time

Always ensure that the temperature of the water being treated is appropriate for the operating conditions. The wash filter should not be installed close to heating systems(over 35–40 °C).

It is very important to monitor the operating pressure. If the norm is exceeded, the entire system may be damaged, and a lot of financial costs will be required to repair it.

The filter must be washed at least once every six months. You can determine the need for it either by the difference in water pressure or visually, simply by looking at whether the flask is transparent.

To clean the wash filter, you need to use the amount of water specified by the manufacturer, which is passed per unit of time in a safe mode. Do not exceed this value, otherwise there is a high probability of equipment failure.

Washable water filters can be purchased in various configurations, and prices will also vary. In addition, prices may not be comparable for the same products. different manufacturers. Therefore, if you want to purchase the most economical option, choose quality equipment.

On Russian market There are many companies that develop water treatment systems. It is quite difficult to choose one or another type of water filter on your own, without the help of a professional. And even more so, you should not try to install a water treatment system yourself, even if you have read several articles on the Internet and it seems to you that you have figured it all out.

It is safer to contact a filter installation company that provides a full range of services: specialist consultation, water analysis from a well or well, selection of suitable equipment, delivery and connection of the system. In addition, it is important that the company provides and service maintenance filters.

One such company is Biokit, which offers online wide choose systems reverse osmosis, water filters and other equipment that can return tap water to its natural characteristics.

Biokit specialists are ready to help you:

connect the filtration system yourself;

understand the process of choosing water filters;

Equipment that performs mechanical water purification and does not need periodic replacement is called a wash filter. Due to this feature, such a device is a more economical option in contrast to models with replaceable cartridges. There are models of washing filters that perform washing independently, that is, in automatic mode.

Peculiarities

Such a system consists of several elements.

Namely these:

• it has a flask, which is equipped with an inlet and outlet pipe;
• The filter includes a mesh and rotary valve, which is installed in the lower outlet from the flasks;
• pressure gauge, flushing drive and other automatic system, but the components are not present in every model.

According to the cleaning principle, such a system is quite easy. In this case, the mesh is installed in the lower and upper parts of the flask, water enters the flask through the inlet pipe and flows through the cleaning cells, where dirt and harmful impurities remain, and then under pressure the water is supplied to the faucet.

The peculiarity of such a filter lies in the density of the filter surface: the denser the cleaning element, the better the cleaning.

This system has another hole, which is located at the bottom of the cleaning flask. This hole is closed when the filter is in operation.

After some time has passed, the purification cells may become dirty, and purified water will flow under low pressure.

In this case, it is necessary to open the bottom valve, and water, under its own gravity, will begin to flow down. This way the mesh is washed. After you are sure that it starts coming out of the hole pure water, the valve must be returned to its original position.

Modern models Such filters are equipped with the ability to connect the lower drainage to the sewerage system through a hose. If this is not possible, then you will have to constantly place the container under the drainage and monitor its filling.

But also a feature is the fact that such filters are designed to purify cold water, and with hot water they can't cope.

But there are filter models that are universal. Such options can be installed for both cold and hot water. The housing of such filters is made of brass or bronze. The main disadvantage of such systems is their high cost. If we compare the cost of universal filters with the cost of cold water filters, then plastic devices are significantly cheaper. In addition, if the plastic is transparent, then the owner has the opportunity to determine the level of contamination of the cells.

Principle of operation

Basically, self-flushing water purification systems have meshes. In such cases, the water is purified by passing through their cells. Fine mesh nets stop all contamination. Thus, dirt accumulates on them. This accumulated layer of dirt interferes with the normal passage of water, so the water pressure decreases.

The most simple option remove accumulated dirt from the mesh- this is to remove the mesh from the flask and rinse it under running water, and then install it on your seat. This work is not difficult, but it takes some time.

Modern systems Self-cleaning filters are cleaned automatically.

But to do this, you need to open the bottom valve and wait for the result. After opening the tap, water under its own weight begins to flow into the lower hole and thus washes and removes dirt from the mesh. If you did not take care of designing the outlet when installing the system, then during the cleaning period you will have to periodically change the container into which the dirt and water will be drained.

Kinds

Standard models of filters with mesh are those in which it is necessary to manually wash the dirty mesh. But there are many such models. Some of them must be disassembled to remove and wash the mesh, while some can be washed without disassembly.

These filters are divided into two types.

• Filters with automatic mesh washing. Such systems do not require human intervention, since the mechanism independently begins the cleaning process after a signal from the pollution sensor. Instead of a sensor, a timer and a filling alarm can be installed.

Models with semi-automatic washing. In this case, the person acts as the trigger for the flushing process. Cleaning in this case depends entirely on the constituent elements of the filter and on the design of the device itself.

These two types of systems can be used for heavily loaded systems. For example, with water supply systems, for a service system for facilities with a large amount of water consumption.

Such filters are also divided into types according to the materials that were used to make the housing. The body can be made of polypropylene, plastic or metal. If the products are made of metal, then brass, bronze or steel are used for production.

As for the elements themselves that carry out the cleaning, they come in three types.

• A mesh with small cells can be made of polypropylene or metal. These components are mainly used for domestic use, but these meshes clog much faster than other types of cleaners.
• Porous discs are made under the influence of a press, which is under high pressure.
• A backfill cleaner that creates a porous structure after compaction.

These cleaning systems can be additionally equipped with pressure gauges, an element for reducing pressure and have a water hammer protection system.

Advantages

The filter, which is self-cleaning, has a large number of advantages. With the help of such advantages, you can save your time, since there is no need to regularly replace filters, and the system itself has a long service life. That is, the owner saves not only his time, but also finances.

The main advantages of such systems:

• if flushing is performed, there is no need to shut off the water supply;
• this filter is able to perform its function without interruption;
• the ability to replace system elements with newer ones, for example, you can install a mesh with smaller cells.

These are not all the advantages of a self-cleaning water purification system. If we take into account even the above advantages, it becomes clear that this cleaning principle is convenient to use and very profitable.

Installation

Each system is supplied with a passport, which indicates the installation process. A self-cleaning water filter with a large flask is designed for water purification from dirt. On sale there is a self-cleaning filter with reverse and forward flushing with a counter. Thanks to this design, the user has the opportunity to control the waste of liquid.

When installing such filters, you must follow all instructions and safety rules for connecting systems to the water supply. It is also necessary to adhere to technical, sanitary and hygiene requirements to the cleaning system.

The installation of such a device must be done in a heated room, since in cold weather the water in the system may freeze. The installation itself is carried out with the cleaning flask facing down. In this case, the pipeline can be either vertical or horizontal.

When performing installation, an important task is not to confuse the directions of water flow. An arrow indicating the direction is located on the lid of the flask. If the cleaning system has an automatic flushing system, then it must be connected to electricity.

In the event that you purchase a filter for cleaning hot or cold water supply from the central line, which may have the ability of coarse or fine cleaning, then for correct use the best option There will be a system with a backwash function. Such a system can be used to purify water in a summer cottage.

Although such a system is washed automatically, experts still recommend washing the mesh manually. But it is necessary to carry out such work much less frequently than changing the filter in another model of cleaning systems.

If we compare filters for water purification with a mesh purifier and with a disk one, then in this case the disk purifier is considered the best, since it has greater productivity due to larger area filtration.

This performance figure often depends on the size of the filtration unit. But a disk filter is demanding on the water pressure in the system, unlike a mesh filter, and the cost of such a filter is significantly higher.

According to the advice of experts, before choosing a cleaning system, you must first determine the parameters necessary for you.

Namely:

• will the installed filter be a separate system for one tap, or will it be installed in the system before the water supply, which only enters the house;
• you need to decide on the type of filter and whether it is compatible with the water supply system;
• choose a filter manufacturer and its cost.

The most reliable systems are considered to be filters from the Danish company Honeywell. These filters are equipped with a backwash system and additional elements. Products from this company are highly wear-resistant and resistant to pressure changes in the water supply system. The main disadvantage of such systems is their high cost.

Mechanical impurities are one of the most common things that you can encounter when consuming water, even from a water supply system (which has already gone through the water treatment stage, ideally). There are many options for how to deal with such contaminants.

1.1 Types of filters for removing mechanical impurities

Another wash-type filter model, inlet diameter ½ inch

The main types are as follows:

• Coarse cleaning methods are used (particles ranging in size from 20 to 100 microns are removed);
• Fine purification methods are used (water is purified from particles 1-5 microns in size).

Separately, we consider the so-called “mud filters” (including industrial ones), the task of which is to keep dirt from entering the system (we are not talking about fine cleaning here, they can be used when supplying water from a well).

In this case, filters are installed mainly at the outlet of the well. This is done so that the water is purified on the approaches from the well, and enters the system in a suitable form.

If a well is used as a source of water, coarse purification will be indispensable in the water treatment system (as well as fine purification products).

Methods for cleaning the filter are divided into:

• Flushing (usually main);
• Non-washable (usually a cartridge is used).

A special feature of filters that use a cartridge (including fine filters) is that it is impossible to wash the filter cartridge; after the end of its service life, it must be replaced.

At the same time, cartridges for filtering hot and cold water are not interchangeable, since a temperature greater than that for which the housing is designed will deform it or the cartridge.

In addition, you need to take into account that the life of the cartridge may vary depending on the composition of the water, and if it is necessary to replace it, you will have to shut off the water supply.

A wash filter (including a main filter) requires one or another method of cleaning the filter element.

The same blocks for hot water are usually opaque and metal. The transparent housing of the cold water filter sometimes allows you to “assess its condition by eye.”

2 Which mechanical cleaning filter to choose?

If you buy a main hot or cold water filter using coarse or fine cleaning methods, for household use, a model with the possibility of backwashing will be more convenient (also suitable for supplying water from a well).

Despite the fact that the main filter can be washed in one way or another without turning off the system, it is recommended to wash the mesh separately (that is, still turn off the system for a while), but this is done much less frequently than the need to change the cartridge.

If we compare the types of filters (regardless of whether they are intended for hot or cold water and what methods they use) - mesh or disk - it is often mentioned that the disk type of filter under similar conditions has greater productivity due to its larger filtration area.

But, a big gain can only be provided by the difference in the size of the filtration unit, and with similar sizes, both mesh and disk filters show the same indicators for the water passed through them (including in the case of fine purification).

At the same time, a coarse or fine disk filter may be more demanding on the incoming water pressure than a mesh filter, and may also be more expensive.

Before purchasing, you should decide on the parameters of the system on which the filter will be installed using coarse cleaning methods, and it is planned to be used for hot or cold water.

If the main filter is installed separately, it is necessary to check that the pipe connections and the diameter of the pipe and filter connections are compatible (or take care of their adjustment).

If a cartridge-type filter is installed in a block filtration system, you must also ensure that all blocks are compatible.

Accordingly, the choice is based on the following parameters:

• Is the filter separate or will it be installed in a multi-stage system. Sometimes a main filter is installed on a pipeline in a separate apartment, for example;
• What type of filter will be installed and whether it is compatible with the piping system (filter operating methods);
• Depending on the chosen type, the manufacturer and cost are determined.

Among the direct products of various manufacturers, we can mention filters (coarse and fine) Honeywell or Atlas, and from manufacturers in the CIS countries - the Russian Geyser.

The products of the Danish company Honeywell are distinguished by their reliability and build quality. Filters of this type from Honeywell are usually equipped with a backwash system. You can also expect additional equipment from Honeywell filters (with a built-in pressure gauge, for example).

Honeywell filters are also highly durable and resistant to pressure changes, since the filter housing is made of durable brass (a feature of these Honeywell products). The only downside here can be the cost, that is, Honeywell filters are less affordable.

Filters for water purification from the company, according to the manufacturer, compete with European analogues and are used both in Russia and in European countries.

Under the Geyser brand, both individual types of filters for mechanical cleaning and entire systems for various purposes are produced ( comprehensive cleaning water for cottages and country houses, cleaning technology for enterprises).

As a result, several specialized Geyser solutions compete with more universal analogues. The Geyser company produces both mesh filters and filters that use a cartridge. A comparative advantage of Geyser is also its price (compared to the previous manufacturer).

Thus, Geyser products will be more budget option. Therefore, when choosing between Geyser and Honeywell, we will prefer Geyser in terms of cost, and Honeywell in terms of quality.

filters with pressure gauge in Moscow

A filter with a pressure gauge is a complex device that allows you to simultaneously purify water and control the pressure inside the pipeline. Devices of this class are installed on a straight section pipes, do not require the creation of additional bends - pipe fragments and the filter are connected in series.

Filters of this type belong to wash filters, that is, their principle of operation is based on the fact that water passes through a cleaning cartridge and then enters the pipeline already purified, that is, it bypasses the filter element directly along the route.

These filters already contain pressure gauge or have a special connector for connecting it. Using a pressure gauge allows you to monitor the pressure of the working medium inside the pipes in real time, and also allows you to indirectly control the degree of filter clogging. By the way, the flask of most filters of this type is self-cleaning: when you open a special valve at the bottom of the filter, all contaminant particles are washed out of it - and filter ready for effective water purification again.

Depending on the characteristics of the materials from which they are made, filters with pressure gauges are divided into universal ones and those that can only be used in cold water supply networks. Universal, as the name suggests, can be used in both cold and hot water supply networks, as well as in heating systems.

We will help you choose a filter with a pressure gauge that is best suited for your case. If you purchase a filter separately with a connection for a pressure gauge, we will help you choose a pressure gauge for it, and we are also ready to advise you on the choice
