INERTIAL FILTER Russian patent published in 2007 - IPC B60H3/06 B61D27/00 B01D45/08 

FIELD: mechanical engineering; ventilation systems.

SUBSTANCE: invention is designed for ventilation systems of passenger cars and other vehicles. Proposed inertial filter contains air intake screen 1 mating with air channel inside which filtering unit is placed in housing 2. Filtering unit consists of distributed rows of converging tubes 3 and ellipsoid-section dust trap tubes 4 whose lower part is connected with dust collector 5. Space of dust collector is connected by tube 6 with aerodynamic clearance 7. Distributed rows of converging tubes and dust trap tubes, their geometry and arrangement provide high degree of air cleaning and reduction of aerodynamic resistance.

EFFECT: improved cleaning of air in ventilation system.
