FIELD: sorption type filters for purifying of air from toxic substances including radioactive dust, biological aerosols, toxicants, in particular, destruction of chemical weapons, absorption of hazardous admixtures from process air of industrial premises, as well as for purifying of ventilation waste. ^ SUBSTANCE: filter has cylindrical casing with bottom, inlet and outlet branch pipes, cover, and also filtering member and sorption unit, which are located within casing in axially aligned relation therewith. Filtering member is fixed on pin connected to casing bottom, and sorption unit is biased by detachable cover. Ratio of sorption unit height, its outer and inner diameters is 1:(0.97-0.99):(0.76-0.77). Filter of such design allows operational life to be increased by 2-3 times. ^ EFFECT: wider operational capabilities, increased efficiency, reduced air flow resistance, and provision for replacement of used filtering member and sorption unit. ^ 1 dwg |
