Analytical aerosol filters AFA
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.
|Filter type||Application||Filter name by a method of analysis||Polymer in fibers|
|AFA-HP||Concentration, chemical and radiochemical composition test for aerosols||Chemical||Perchlorovinyl|
|AFA-RMP||Determination of volumetric activity of aerosols||Radiometrical||Perchlorovinyl|
|AFA-RSP||Determination of volumetric activity and isotope structure of aerosols||Radio spectrometrical||Perchlorovinyl|
|AFA-RGP||Determination of the size and activity of aerosol particles||Radiografrical||Perchlorovinyl|
|AFA-VP||Determination of so-many parts in the volume of aerosol||Mass analysis||Perchlorovinyl|
|AFA-DP||Definition of dispersity of aerosol using microscope||Dispersive||Perchlorovinyl|
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 cm2.
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.
