ASSEMBLY FOR DELIVERY OF AIR CONTAINING PARTICLES, AND FOR SEPARATION OF PARTICLES FROM AIR Russian patent published in 2015 - IPC A47L9/22 

FIELD: heating.

SUBSTANCE: assembly (2) for delivery of air containing particles (5) and for separation of particles (5) from air includes housing (10) having space (20) for intake and accumulation of particles (5), and air delivery device (30) arranged inside housing (10) and containing the primary fan (31) intended to deliver air from space (20) for accumulation of particles, and another fan (32) intended to separate particles (5) from air. There is gap (22) between the fan structure of air delivery device (30) and housing (10), and in order to avoid the air flow containing particles (5), through gap (22), at least the bigger portion of the primary fan (31) is not covered.

EFFECT: preventing relatively strong delivery action based on interaction of an outer surface of primary fan (31) with a fixed wall.
