2.3 Air flow
Air drawn through the air intake filter (optional), the inlet protection screen and the inlet non-return
valve is displaced by the vacuum pump element towards the air end exhaust valve. This valve ejects a
mixture of air and oil into the exhaust filter element. After passing the exhaust filter element, clean air -
conditioned to a few parts per million - is discharged through the outlet.
The vacuum pump is driven by an electric motor.
