Air Filter

What is bag filter?

Bag filters, made of synthetic fiber material, have high dust holding capacity and superior performance. Bag filters are manufactured with 500 mm and 600 mm depths are manufactured with special dimensions. Synthetic fiber bag filters are utilized in air-conditioning systems. In hygienic air conditioning systems they are assembled in the air handling unit with a view to keep the large particles and protect the HEPA filters. Synthetic fiber bag filters perform filtration in the “G3 (EU4) – G4 (EU4) – F5 (EU5) – F6 (EU6) – F7 (F7) – F8 (EU8 ) – F9 (EU9)” classes.

What is activated carbon filter?

Active carbon filters have the ability to capture and keep gas molecules. The surface of the active carbon filter consists of millions of tiny pores. Odor-emitting toxic gases are captured thanks to cited pores. Activated carbon filters should be replaced depending on pollution of the media air where they are used and frequency of use. For example activated carbon filters should be replaced every 3 to 6 months, in a smoking environment. Activated granular carbon filters are used as odor eliminator filters in places where heavy odors occur. When the filter gets dirty in activated granular carbon filters only granular carbons are replaced. There is no need to change the cells of the filters.

What is Cassette Filter?

Cassette panel filters are made ​​of specially blended fiber raw materials with controllable and renewable and have an extremely durable structure. The protection cage around it is placed with an eye to protect the filtering feature from impacts. Cartridge panel filters are “G2 (EU2) – G3 (EU3) – G4 (EU4) – F5 (EU5) “class filters. Cartridge filters are produced as cellulose based and fiber glass based.

When should the filters be replaced?

The resistance that the filter shows against the airflow when it is clean is called initial resistance or pressure drop. The unit of pressure measurement incident to foregoing is called as Pa (Pascal) value. This value increases as the filters get dirty. The filters whose resistance value reaches the recommended final resistance must be replaced.

The last resistance values ​​determined for prefilters and bag filters are recommended according to EN 779 European standards and you can examine these technical values ​​ on our website at www.alpfiltre.com.

What is the life of filters?

The answer to this question depends on the air pollution where the filters are installed. Factors such as elimination or addition of the air pollutants, and seasons have impact on the life of the filter.

Based on our experience we can say that the life of the cassette filters are 2 to 3 months while that of bag filters are 4 to 6 months and life of HEPA filters are 6 to 12 months.

Which filters are washable?

Prefilters that have polyurethane or metal internal structure are washable. Bag, HEPA and ULPA filters filter invisible particles by attracting and attaching them to the fibers of the filter on the basis of molecular attraction. These types of filters cannot be cleaned, repaired or replaced.
