Filtering units

Active air filter AFP


The AFP active air filter is a suitable solution for filtering the air from dust and gas contaminations formed at production processes. It absorbs the vapours of hazardous chemical compounds as: styrene, xylene, toluene, benzene, alcohols, phenol, acetone, petrol, turpentine, acetates, esters, acrylonitrile, chloride derivative, chloroform and other. It is used in different applications as: pharmaceuticals, chemical and plastic industry, food production and similar. Simple use, ergonomic solution and high efficiency in capturing gaseous contaminations as well as vapours of hazardous compounds are its general advantages.

The active air filter consists of:

  • radial fan
  • housing displacing on castors
  • filters:
    a) needled fabric filter
    b) pocket filter
    c) carbon (2 cassettes with activated carbon)
  • control unit
  • hour-meter to measure the work time

The dust pollutants are captured by the needled fabric filter and pocket filter, whereas gases and vapours are absorbed by the carbon filtering layer. The device is equipped with a pressostat indicating the pollution degree state of the dust filters. Absorbtivity of the active filter ranges in 20–30 % of the activated carbon weight. This enables to capture 6.6–11 lbs (AFP-1) and 14–22 lbs of gases (AFP-3) and furthermore it gives approximately 120 or 200 work hours respectively (measured by the hour meter). After these values are exceeded, replace the activated carbon cassette.
