Gast 6AM-FRV-5A Reversible Air Motor 4 Hp Foot Mount

Product Description

The GAST 6AM-FRV-5A is a reversible, foot-mounted air motor rated at 4 horsepower and designed for industrial and manufacturing applications where pneumatic power is required. Driven entirely by compressed air, it produces up to 115 inch-pounds of torque across a speed range of 300 to 3,000 RPM. The motor features a keyed 5/8-inch diameter shaft with a 1.39-inch shaft length and an overall length of 7.47 inches. Weighing 22 pounds, this unit is installed by industrial maintenance technicians, millwrights, and mechanical contractors in facilities where electric motors are not suitable due to hazardous or wet environments.

The 6AM-FRV-5A is used in applications requiring variable-speed or reversible rotation driven by plant air systems. Foot-mount configuration allows direct bolting to a base plate or structural support. The motor accepts a maximum working pressure of 100 psi and delivers a maximum air flow of 128 CFM. Typical installations include conveyor drives, hoists, agitators, winches, and other light-to-medium duty industrial machinery where compressed air is the preferred power source.

Compatibility

Designed as an OEM-style pneumatic air motor for industrial machinery and equipment requiring a foot-mounted, reversible 4 HP air-driven power source operating on standard plant compressed air supply.

Installation Notes

Installation is typically performed by licensed millwrights or industrial maintenance technicians. Isolate and depressurize the compressed air supply line before mounting or connecting the motor. Secure all air line fittings to the rated working pressure before operation, and verify that the supply pressure does not exceed 100 psi. Consult applicable OSHA and local machinery safety codes for guarding requirements on exposed rotating shafts and couplings.
