FIELD: the invention is designed for filtration. ^ SUBSTANCE: the unit of an air filter has a body with an air inlet and an air outlet openings; a partition dividing the body into a filtering chamber and a chamber of clean air; a filter construction including a packet of goffered filtering medium and communicating with the chamber of clean air. At that the packet of goffered filtering medium includes a sublayer, at least partially covered with a layer of a thin fiber holding polymer of condensation distinguishing from copolymer shaped from cyclical lactams and monomer diamine C6-10 or two acide monomer C6-10 and a gummy addition including an aromatic oligomer having molecular weight in the order of approximately from 500 till 3000 in which the addition is mixed with the polymer of condensation. The mode of filtration includes passing of the air through the proposed unit of the air filter. ^ EFFECT: provides high effectiveness of filtration of flows at high temperatures, high humidity, high expenditures. ^ 12 cl, 27 dwg, 2 tbl, 18 ex |
