GAST Motors

Start with the torque and speed your load needs, then check the air pressure and flow your compressor can deliver at the motor. GAST publishes performance curves for each frame size, so match the curve to your duty point rather than the peak rating, and allow margin for continuous running.

A rotary vane air motor delivers high speed at lower torque directly from the shaft. A GAST air gearmotor adds a gear reduction, trading speed for higher torque and better control at low rpm — often the better choice for conveyors, mixers and indexing drives.

Yes. Alongside complete motors, gearmotors and compressor/vacuum pump assemblies, we stock GAST replacement parts for air motors and gearmotors plus air motor mounting brackets. Share your model and serial details and we will confirm the correct item and lead time.
