FIELD: mechanical engineering. SUBSTANCE: front and rear tube plates air cleaner are made as part of housing. Front tube plate is mounting plate for filtering elements, each consisting of nozzle-diffuser and dust trap. This front tube plate is arranged between nozzle-diffusers and dust traps interconnected by thread. Filtering elements pass freely through holes in rear tube plate. Each element is sealed in rear tube plate by rubber ring enclosing conical surface of filtering element and adjoining the plane of rear tube plate. Housing is connected with main flow air ducts and suction flow air duct through edges located in one plane and resting against seals of air ducts.
