AIR CLEANER Russian patent published in 2010 - IPC B01D50/00 F24F3/16 

FIELD: process engineering.

SUBSTANCE: proposed invention is intended for air treatment. Proposed air cleaner comprises first flow channel communicating intake hole with exhaust hole, first cleaning assembly arranged in said first channel and performing first cleaning of air passing there through from upstream side to downstream side, second flow channel communicating the space between first cleaning assembly and first channel exhaust hole with the space between first cleaning assembly and first channel intake hole, air blower arranged in first channel between first cleaning assembly and connecting section on downstream side. Said connecting section represents downstream side of connecting sections between first and second channels. Note here that aforesaid blower generates positive pressure nearby exhaust hole and connecting section of downstream side. It comprises also second cleaning assembly arranged in second flow channel and performing second cleaning function. Tail part of upstream side of second flow channel comprises at least a section passing to, in fact, the center of surface perpendicular to first flow section flow direction.

EFFECT: high cleaning efficiency.
