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.
