Gast 4AM-NRV-54A Air Motor the compact and portable 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.
Why use a Gast Air Motor?
You can vary air motor speed between 300 and 10,000 rpm (depending on model selection) with a simple valve put in between
the air source and air motor.
A four-way valve in the air line enables a Gast Air Motor to be instantly reversed. A turn of the valve causes a complete reversal
of rotation, even when the motor is running at full speed.
