Tuthill Kinney

Kinney vacuum boosters are lobe type, positive displacement units, designed with extra heavy shafts and bearings to permit high power input. They incorporate a unique rotor profile in which all gas joints or mating surfaces are sealed vacuum tight.

Unit construction consists of two figure-eight shaped rotors enclosed in a precision machined housing supported at each end by precision bearings. The power drive turns the drive rotor directly and rotates the driven rotor by means of specially forged, heat treated, crowned and ground precision helical gears.

Efficient and effective vacuum pumping is accomplished by trapping a volume of gas at the booster inlet and between each rotor and the booster housing. This volume of gas is quickly and cleanly evacuated by the fast revolving rotors which carry the air to the exhaust side of the booster where the air is then discharged to the backing pump.
