AFA filters are intended for separation of the disperse admixtures from a gas phase at study or testing of an aero disperse system (aerosol).
The basic range of applications of AFA filters:
Studying and testing of the radioactive, toxic and bacterial aerosols presenting in air of a working zone of manufacturing premises, in near ground atmosphere layer;
Studying and testing of the radioactive, toxic and bacterial aerosols presenting in ventilation and technological air streams;
Studying and testing the performance of the gas cleaning devices, individual and collective protection aids for aerosols or other similar filtering devices;
Conducting research and development works in the field of aero disperse systems.

The filtering element of filters AFA - RSP, AFA - RMP, AFA - RGP, AFA - DP is fastened to a paper base ring with a flange, that construction is inserted into a paper protective ring. The filtering element of filters AFA-WP and AFA-CHP is inserted directly into a protective ring. A work surface of filters is 20 см2.
The warranty period for the storage of AFA filters from the moment of their fabrication is:
FPP-15-1.5 - 4 years;
LFS-2 - 2 years;
NEL-3 - 9 years.
