Features

  • Gast air motors operate pneumatically and hence do not produce electric sparks for operating in hazardous locations or extreme temperatures.
  • They feature a gear reducer assembly for operation in high torque & low-speed applications.
  • These units come with a variable speed drive for adjusting the motor power output and operating speed to meet the application requirements.
  • They offer no-load speeds up to 3000 rpm and are available in shaft diameters ranging between 3/8 and 1 inches.
  • These units have aluminium or cast iron housing with a steel (selected models) output shaft for enhanced strength.
  • They also come with a gear reducer for high torque and resisting damages when stalled or overloaded for a long time.
  • These motors allow CCW or REV rotation and are available in power outputs ranging from 0.33 to 9 hp.

Frequently Asked Questions

What size air line is recommended for Gast air motors?

It is recommended that the size of the air line should be one size larger or the same size as the port.

How often should the air filter be checked for Gast rotary vane motors?

It is recommended that the filters should be cleaned, inspected and / or replaced after 500 hours of operation.

Can Gast air motors be mounted in any position?

They offer a C-face, foot or hub mounting design that allows the user to install it in these positions, depending upon the application requirement, for enhanced stability.

What type of oil should be used for lubricating Gast air motors?

A 10 wt detergent oil is suitable to lubricate Gast air motors. However, a 10w30 detergent oil can also be used as a substitute.
