The first (internal) layer of the dispersing coating is made as a fibrilliform filament wound on the external surface of the air conduit with a surface density of 1.1-2.0 kg/sq m, the second (external) layer of the dispersing coating is a porous envelop made of material with chaotically laid fibers of a diameter from 6.times.10.sup.-5 to 21.times.10.sup.-5 m fused at the points of their intersection and applided to the internal layer with a density of 3.5.times.10.sup.2 to 6.0.times.10.sup.2 kg/cu m. The side wall of the air conduit at the point of each recess has a number of radial holes, each having a diameter (d) varying from 0.05 to 0.12 the inside diameter (D) of the tubular air conduit.
