HEPA high-performance filters type FyaS-MP

Filters can also be used to clean exhaust air from dangerous microorganisms and radioactive aerosols in
biological laboratories, nuclear power plants, etc. When cleaning large volumes of air, the filters are installed in a section of pleated filters of the SSF type (see the catalog of NPP Folter LLC).

The temperature of the cleaned air should be in the range – 40C to + 70C and relative humidity no more than 95%.
The environment and filtered air must not contain aggressive gases and vapors. The filter must reach operating mode (reach the required efficiency) in no more than 2 hours from the start of purging. Upon request it is possible to produce filters of other dimensions.

General design of high-performance HEPA filters (FyaS-MP)

FyaS-MP filters consist of a housing, inside of which mini-pleated filter bags are installed in a W-shape,
which is sealed in the housing with a special sealant. The filter housing can be made of a special aluminum profile, galvanized, stainless steel sheet or MDF. The body has a flange (pressing surface) around the perimeter on both sides, the size of which for an aluminum profile is 15mm, for plywood 12mm, and for a body made of stainless steel 18mm, for MDF 10mm. A rubber seal is glued to this flange (on one or both sides).

Maintenance of high-performance HEPA filters (FyaS-MP)

During operation of the filter, its aerodynamic resistance should be monitored using pressure gauge readings. When the pressure drop reaches the value specified in the passport, selected in the project, or based on the available pressure in the ventilation system, the filter must be replaced.
