HEPA-filter "Folter", filters for vacuum cleaners, cell and cartridge: the principle of action, design features

One of the main elements of ventilation systems in living quarters, production plants and many types of equipment are filters, the variety of their constructions is explained by different cleaning methods and types of pollutants. HEPA filter "Folter" is one of the examples of widely used cleaning equipment produced by the domestic enterprise engaged in the creation of air filters and dust collectors for more than 60 years.

Filters from Folter

The research and production company "Folter" was registered on the basis of the laboratory of the Institute TSNIIPromzdaniy in 1995.

HEPA filter "Folter" is the final stage of air filtration in clean rooms of production shops, medical institutions, in pharmacy, electronics, food industry.

Types of HEPA filters: FAS, more powerful FAS-MP. Can be installed in air distribution models MV for the final cleaning of air in rooms or in sections of the FFS, for cleaning large volumes of air.

Cellular filters from "Folter" FyaS

Filters of type ФяС have a cell fold structure.

Purpose: finishing air cleaning with sterilizing effect. They are installed in medical institutions or in shops producing medical preparations, laboratories or other premises that require a high level of air purification.

The HEPA filter "Folter" FAS consists of:

• Housing.
• Filter material that is folded into the body.
• Separators from foil (aluminum) are laid between the filtering material to prevent it from sticking together.
• Instead of foil, special threads can be used that are glued to the material.

The material for the case is:

• Aluminum profile. The depth of the filter is 78, 150, 300 mm.
• Sheet of stainless steel or MDF.

After the filter material has been installed in the housing together with the threads or mesh, sealants are poured around the edges. The body forms a clamping surface with a thickness of:

• Aluminum - 15 mm;
• MDF - 12 mm;
• Stainless steel - 18 mm.

The rubber is adhered to the top and the decorative grating is installed.

Classes of the filter FcS: E10, E11, E12, E13, E14, the efficiency increases with the height of the class from 85 to 99.995%.

HEPA filter "Folter" FyaS-MP - cell folded, containing special miniplitsirovannyi packs Fyas-MP, are designed to handle large amounts of contaminated air at a high rate of filtration. Unlike FyA, it is suitable for installation directly into the air duct of the existing ventilation system.

Air filtration devices in vacuum cleaners

Filters for vacuum cleaners - household filter elements, which are the last barrier before air from the cleaner body back to the living room. Practical all modern models practice the use of one of two types of filtering systems:

• HEPA-filter - stands for "high-efficiency dust retainer" In addition to the basic HEPA filter, vacuum cleaners usually also include conventional foam foam filter elements.
• Water filter.

HEPA filters for vacuum cleaners can be of two types:

• Disposable paper in combination with fiberglass.
• Reusable, consisting of PTFE.

Most often in vacuum cleaners use disposable models of small sizes. They are quickly clogged with debris and reduce the performance of the vacuum cleaner, increasing the engine overheating.

The filter is designed for a delay of 0.1 to 1.0 μm. For HEPO filters, the entry of particles above the norm is highly undesirable, since they accelerate its clogging and reduce efficiency.

Types of water filters:

• Turbulent. The most common simple form. With air, dust and debris get into the water tank, where it remains. Disadvantage - incomplete absorption of dust and the installation of additional filter elements.
• Separator type. Dust with air enters the water in which the separator mechanism is placed, and the dust is safely drawn into the water and does not scatter. More expensive model.

Cartridge filters: types and features

Can be produced for both water and air purification.

Water filters - flow or bulb - are used both in the home for cleaning water for drinking or swimming pools, and in production conditions.

The criterion of choice is the volume of water transmission per hour and the degree of purification.

The degree of cleaning depends on the porosity of replaceable cartridges from 0.5 to 100 μm. Cleaning is not provided, only replacement.

Cartridge pleated dust filter is designed to separate dust particles from gas. Gas enters through the cartridge and exits through the inner hole already cleaned.

Conclusion

The role of filter elements in modern human life is difficult to overestimate. When operating it is necessary to remember the standard rule: a dirty and clogged filter can become an even greater source of contamination than the medium passing through it. Timely cleaning and replacement is a guarantee of obtaining a quality result guaranteed by the manufacturer.
