LOCAL AIR CLEANER Russian patent published in 2016 - IPC F24F7/06 

FIELD: ventilation.

SUBSTANCE: claimed cleaner comprises a plenum filtering blower with the surface for the airflow to force the cleaned uniform airflow out and an air duct arranged from the side from the said airflow surface extending therefrom to the airflow exit to make the through surface at the discharge end. The said blower is arranged to make the said uniform airflow ejected from the airflow surface flow into the air duct. The said uniform airflow, then, collides with an airflow collision surface arranged downstream of the said through surface. The said air duct makes it possible to form an exposed area between the through surface and collision surface by spacing the former opposite and apart from the collision surface. The said uniform cleaned airflow ejected from the airflow surface collides with the collision surface to flow outward from said exposed area. This allows the air cleanliness to be higher inside the air duct than that in the other areas.

EFFECT: simplified design.
