SORBTION FILTERING MATERIAL Russian patent published in 2008 - IPC B01D39/18 B01J20/20 

FIELD: process flows, filters.

SUBSTANCE: invention is related to sorbtion filtering materials used in safety equipment intended for filtering of air from gases, vapors and aerosols. The material consists of air-permeable base surfaces, layer of electrically charged ultrathin polymer fiber for air filtering from aerosols and sorbing layer that contains fixed particles of absorbent carbon consisting of mixture of coal - calalytic agent of the KT type and gas coal of SKT type of fineness 60-80 micron, distributed and fixed in the volume of pulp fibers at rate coal - calalytic agent of the KT type / gas coal of SKT type as 1.15-3.5:1; at that the layer of electrically charged ultrathin polymer fiber is applied in the high voltage field to sorbing layer.

EFFECT: provided possibility of all-purpose respiratory protection from hazardous gases, vapors and aerosols when the material is used in individual and shared air filtering equipment.
