Gast 4AM-FRV-13C Reversible Air Motor 1.5 Hp Foot Mount

Product Description

The GAST 4AM-FRV-13C is a 1.5 HP reversible, foot-mounted air motor designed for industrial and trade applications where pneumatic power is required in place of electric drive. Powered by compressed air, it delivers a maximum speed of 3,000 RPM and a minimum operating speed of 300 RPM, with a maximum working pressure of 100 psi and a torque output of 56 inch-pounds. The keyed shaft measures 0.5 inches in diameter and 1.12 inches in length. Weighing 9 pounds, this motor is sized for bench, machine, or frame mounting in production, maintenance, and process environments.

The 4AM-FRV-13C suits applications requiring variable-direction shaft rotation without electrical hazard exposure — common in paint mixing, conveyor drives, agitation systems, and automated assembly equipment. The foot mount style allows rigid base mounting to a flat surface or machine frame. The reversible air-actuated design makes it well suited for use in environments where explosion-proof or spark-free operation is required. It is installed by millwrights, industrial mechanics, and experienced maintenance technicians in light to medium industrial settings.

Key Features

• Reversible shaft rotation, air-actuated — no electrical connections required
• 1.5 HP output with operating range of 300 to 3,000 RPM
• Maximum working pressure of 100 psi
• 56 inch-pounds of torque for moderate load applications
• Keyed shaft, 0.5 inches diameter, for secure coupling to driven components
• Foot mount style for rigid base installation on flat surfaces or machine frames

Compatibility

Designed as an OEM-style pneumatic air motor for foot-mount installations requiring a 1.5 HP reversible drive at standard industrial compressed-air supply pressures up to 100 psi.

Installation Notes

Installation is performed by qualified millwrights or industrial maintenance technicians. Shut off and lock out the compressed air supply before mounting, coupling the shaft, or servicing the motor. Verify that supply air pressure does not exceed the 100 psi maximum working pressure rating. Ensure the keyed coupling and driven shaft are properly aligned before applying air pressure to prevent premature bearing wear.
