Product Details

The compact 1UP-NRV (GM) series offers variable operating speeds and power output that can be adjusted to meet the precise needs of your application. Their 15:1 gear reducer is not only ideal for lower speed and higher torque applications, but they also can be stalled or overloaded for long periods without damaging the motor. In addition to being a non-electrical device and cool running, Gast air motors are ideal for use in hazardous and extreme ambient temperature locations.
