ABSTRACT:
The air in which the oil particles are suspended is drawn from the environment through an air intake (4) as a result of the vacuum created by a centrifugal aspirator (11) and then passes along a substantially vertical duct (5) in which an internal helical element (6) causes the mechanical separation of the oil particles by centrifugal action due to the rotation of the air imparted by the helix, the oil particles collecting on the wall of the duct (5) from which they drain into a collecting hopper (2), after which the air is further filtered by an additional filter (9, 10) before reaching the delivery opening (13).
