Rotary vacuum pumps

Gast rotary vane air motors use compressed air to create rotary motion of the shaft. Rotary vane jet engines have axial vanes embedded in a slotted rotor, which is mounted eccentrically with respect to the engine housing opening. The vanes extend to seal against the housing opening by means of springs, cam action, or air pressure, depending on the engine design. Torque is developed from the pressure of compressed air acting on one side of the blade, causing the rotor to turn.

Gast offers a complete line of air actuation products in a wide range of pressure and vacuum types and sizes.
