Gast 1UP-NRV-3A Reversible Hub Air Motor 1/2 Hp

Product Description

The GAST 1UP-NRV-3A is a reversible hub-mount air-actuated motor rated at 1/2 horsepower and designed for industrial and trade applications where pneumatic power is required. Driven entirely by compressed air, it operates without electrical power, making it well suited for hazardous or wet environments. The motor delivers up to 6,000 RPM with a minimum operating speed of 500 RPM, giving technicians a wide usable speed range. A flat-shaft output measures 3/8 inches in diameter and 1.14 inches in length. Maximum working pressure is 80 psi. Licensed millwrights, maintenance technicians, and industrial mechanics are the primary installers for this class of equipment.

This air motor is used in industrial process equipment, automation fixtures, and specialty tooling where reversible rotation is required and electrical motors are impractical. The hub mounting style allows direct integration into machine frames and custom assemblies. With a maximum air flow of 27 CFM and a torque output of 6 inch-pounds, the 1UP-NRV-3A fits light-duty continuous-duty pneumatic drive applications. It is appropriate for both OEM production builds and aftermarket maintenance replacement scenarios in manufacturing and process environments.

Compatibility

Designed as an OEM-style replacement or direct-drive component for hub-mount pneumatic motor applications requiring reversible rotation at 1/2 HP output.

Installation Notes

Installation should be performed by a qualified millwright or maintenance technician familiar with pneumatic drive systems. Shut off and bleed the compressed air supply before making or breaking any pneumatic connections. Verify that supply pressure does not exceed 80 psi and that air lines are clean and dry before connecting to the motor. Follow applicable OSHA lockout/tagout procedures whenever the motor is mounted in an energized machine or assembly.
