Gast 1AM-NRV-60-GR11 Reversible Air Motor 0.32 Hp

Product Description

The GAST 1AM-NRV-60-GR11 is a reversible, face-mount air-actuated gear motor rated at 0.32 horsepower. It operates on compressed air and delivers a maximum of 350 RPM with a 15:1 gear ratio and a minimum speed of 30 RPM, making it well suited for applications that require variable-speed control without electrical power at the drive point. The motor accepts a maximum working pressure of 100 psi and a maximum air flow of 21 standard cubic feet per minute. The flat-keyed output shaft measures 0.5 inches in diameter and 1.38 inches in length. Licensed HVAC, industrial, and mechanical contractors install this class of pneumatic motor where spark-free or explosion-proof operation is required.

The 1AM-NRV-60-GR11 is designed for industrial and commercial pneumatic drive applications where shaft rotation must be reversible on demand. Typical installations include conveyor drives, valve actuators, agitators, and positioning systems that rely on plant air supply rather than electric motors. The face-mount configuration allows direct mounting to gearboxes, brackets, or equipment panels. Its compact envelope, at 2.93 inches in diameter and 6.87 inches in overall length, fits into tight mechanical assemblies. This motor is well suited for environments where moisture, dust, or flammable atmospheres make electric motors impractical.

Key Features

• Reversible shaft rotation for bidirectional drive applications
• 15:1 gear ratio with a speed range of 30 to 350 RPM
• Rated torque of 71 inch-pounds for moderate-load pneumatic drives
• Face-mount style for direct panel or gearbox attachment
• Operates at up to 100 psi working pressure with a maximum air flow of 21 SCFM
• Flat shaft type, 0.5 inches in diameter, simplifies coupling and sprocket installation

Compatibility

Designed as an OEM-style replacement or direct-application pneumatic gear motor for industrial face-mount air motor installations requiring reversible operation at 0.32 HP.

Installation Notes

Installation should be performed by a qualified mechanical or industrial technician. Isolate and bleed the compressed air supply line to zero pressure before removing or installing the motor. Verify that the supply air is clean and lubricated per the manufacturer service requirements for the air motor class. Confirm that the regulated inlet pressure does not exceed 100 psi during operation to avoid seal and gear damage.
