Abstract

The particles remover comprises a transparent box (1) with claws (2) to permit locking to the motor casing (3) of a suction pump comprising a motor (5) and turbine (4). At the other end of the box is a nozzle (6) attached by a rim (7). A cylindrical receiver (8) with several compartments is of slightly greater diameter than the rim and is supported (9) at the entry to the box. The support comprises a centralising disc (10) adjacent to the large opening which has a supporting ring (12) under the receiver. The receiver (8) is sterilised before insertion in the collector and collects particles suspended in the air.
