These rotating vane mini vacuum pumps, when needed, can be used even for
compressing air. They are composed of a single-phase induction electric motor with
condenser, a sintered metal self-lubricating stator, a white metal rotor fitted onto
the motor shaft and slotted for housing the hardened steel vanes and a silencer on
the exhaust. The operation principle is the same as that of the larger series of vane
vacuum pumps. They are noiseless and lubrication-free and require no maintenance.
Thanks to their minimal overall dimensions and their reduced weight, they are
particularly suited for being installed on portable equipment.
They are suitable for discontinuous, non-intense use.
