The air polluted by oil mist or coolant is channeled inside the centrifugal filter crossing the inlet providing a grid so as to prevent the suction of solid material.

A conic diffuser guarantees the uniform distribution inside the drum of the mist and vapor that are centrifuged at high speed and then pushed towards the filtering panels. While crossing the panels, the particles undergo a coalescence effect turning into droplets and then discharged through a drainpipe.
