Gast 6AM-NRV-22A Reversible Flange Air Motor 4 Hp

Product Description

The GAST 6AM-NRV-22A is a 4 HP reversible flange-mount air-actuated motor designed for industrial and trade applications where compressed air is the preferred or required power source. Rated to 3,000 RPM maximum and 300 RPM minimum, it delivers 115 inch-pounds of torque at up to 100 psi working pressure. The keyed shaft measures 2.06 inches in length and 5/8 inch in diameter. A licensed industrial mechanic or maintenance technician typically installs this unit in pneumatic drive systems, conveyor lines, or equipment where variable speed and reversible rotation are required without electrical power at the point of use.

This motor suits industrial facilities, manufacturing environments, and hazardous locations where air-powered drive equipment is specified. The reversible shaft rotation makes it appropriate for applications requiring bidirectional operation such as winding equipment, hoists, mixers, and actuated assemblies. With a flange mount configuration and an overall diameter of 6.5 inches and overall length of 8.29 inches, it fits into standard flange-mount drive housings. Maximum air flow is rated at 128 CFM at full load.

Compatibility

Designed as an OEM-style replacement or direct installation air motor for industrial flange-mount pneumatic drive systems requiring a 4 HP reversible configuration at standard shop air pressures up to 100 psi.

Installation Notes

Installation should be performed by a qualified industrial mechanic or pneumatic systems technician. Isolate and bleed down the compressed air supply fully before mounting or servicing this motor. Verify that the supply line pressure does not exceed 100 psi and that the air supply is properly filtered, lubricated, and regulated per the system design. Secure all flange fasteners to the equipment manufacturer's specifications and confirm shaft alignment before returning the system to service.
