Gast 4AM-70C-CB20 Gear Motor

Gast 4AM-70C-CB20 Gear Motor the compact offers variable operating speeds and power output that can be adjusted to meet the precise needs of your application. Their 20:1 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.

Why use a Gast Air Motor?

Variable Speed
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.
Non-electrical Sparking
As a non-electrical device, the possibility of explosion from igniting flammable gases is greatly reduced.
Instantly Reversible
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.
