Gast Air Motor 4AM series offers air motor operating speed and power output that can be adjusted to meet the precise needs of your application. Their air throttling and pressure control is not only cost-effective over electric motor controls, but they also can be stalled or overloaded for long periods without damaging the motor. In addition, these Gast air motors are cool running and have no electrical spark, which makes them ideal for use in hazardous locations.
