Air and Gear Motors

Known industry wide for their rugged construction and reliability, Gast Air Motors and air powered Gearmotors are available in both lubricated and oilless models.

These air motors and gearmotors are used in many industrial applications, from mixing equipment to running pump drives.

• Self-sealing vanes take up their own wear, ensuring consistent output for thousands of hours of use

• Variable speed capabilities allow flexibility and versatility in any number of applications

• Cool-running operation means air motors can be used in ambient temperatures of up to 250° F (120° C)

• Non-electrical operation reduces the possibility of explosion from igniting flammable gases
