Product Details:
The compact and portable Gast 4AM series air motor provides operating speed and power output that can be adjusted to meet the precise needs of any application. The Gast 4AM-ARV-119 motor features air throttling and pressure control that are not only cost effective over electric motor controls, but they also can be stalled or overloaded for long periods without causing any damage. In addition, it is cool running and have no electrical sparks, which make it ideal for use in hazardous locations. The ability to instantly start, stop and reverse (RV models) eliminates the operational delays associated with electric motor speed up and slow-down periods.
