Gast 1AM-NRV-39A Reversible Hub Air Motor 0.32 Hp

Product Description

The GAST 1AM-NRV-39A is a reversible hub-mount air motor rated at 0.32 horsepower and capable of reaching up to 10,000 RPM at a maximum working pressure of 100 psi. Designed for compressed-air-driven applications where reversible shaft rotation is required, this motor uses a round shaft measuring 1.13 inches in length and 3/8 inch in diameter. The overall body diameter is 1.75 inches with an overall length of 4.25 inches. It produces up to 71 in-lb of torque and operates at a minimum speed of 400 RPM. Licensed HVAC, industrial, and mechanical technicians install this type of air motor in pneumatically powered equipment and tooling systems.

The 1AM-NRV-39A fits applications that require a compact, hub-mounted pneumatic drive with bi-directional rotation capability. Typical use cases include industrial automation, pneumatic tooling, and light-duty conveyor or actuator systems where electric motors are impractical or hazardous. The motor accepts air flow up to 20.5 SCFM and is suited for installations in facilities with existing compressed-air infrastructure. Its small footprint makes it adaptable to confined mounting arrangements in both production and service environments.

Key Features

• Reversible shaft rotation for bi-directional drive applications
• 0.32 HP output with a maximum speed of 10,000 RPM and minimum of 400 RPM
• Maximum working pressure of 100 psi
• Up to 71 in-lb of torque output
• Compact hub-mount design at 1.75 inches overall diameter and 4.25 inches overall length
• Round 3/8 inch diameter shaft, 1.13 inches long, for straightforward coupling

Compatibility

Designed as a direct OEM-style replacement air motor for hub-mount pneumatic drive systems requiring a reversible 0.32 HP motor with a 3/8 inch round shaft.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with pneumatic systems. Depressurize and lock out the compressed-air supply before removing the existing motor or making any connections. Verify that the supply pressure does not exceed 100 psi and that air flow is within the rated 20.5 SCFM maximum before startup. Confirm shaft coupling alignment prior to resuming operation to avoid premature bearing wear.
