Gast 8AM-NRV-28A Air Motor 5 Hp Reversible Nema 145TC

Product Description

The GAST 8AM-NRV-28A is a 5 horsepower reversible air-actuated motor built to NEMA 145TC frame standards. It converts compressed air into rotational shaft output, making it suited for hazardous or washdown environments where electric motors are not appropriate. The motor delivers up to 2,500 RPM maximum speed with a minimum operating speed of 300 RPM, and produces 185 inch-pounds of torque. The keyed shaft measures 0.875 inches in diameter and 2.13 inches in length. Licensed HVAC technicians, industrial mechanics, and millwrights typically specify this motor for pneumatically driven equipment where variable speed and reversible rotation are required.

The 8AM-NRV-28A is designed for industrial and commercial pneumatic drive applications. Its reversible rotation capability allows the motor to change direction without additional mechanical components, which is useful in conveying, mixing, and positioning systems. The NEMA 145TC mount style provides a standardized footprint for direct-drive or coupled installations. The motor operates at a maximum working pressure of 100 psi and handles a maximum air flow of 175 cubic feet per minute, supporting consistent output across variable supply conditions.

Key Features

• Keyed shaft output at 0.875 inches diameter and 2.13 inches length
• NEMA 145TC mount for standardized, drop-in frame compatibility
• Operating speed range of 300 to 2,500 RPM for variable-speed applications
• 185 inch-pounds of torque at rated conditions
• 100 psi maximum working pressure with 175 CFM maximum air flow

Compatibility

Designed as an OEM-style replacement or direct installation air motor for equipment using NEMA 145TC frame-mount pneumatic drive assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with pneumatic drive systems. Shut off and lock out the compressed air supply before mounting or servicing the motor. Verify that supply air pressure does not exceed 100 psi and that the air supply is clean, dry, and lubricated per the manufacturer's requirements. Secure all fittings and confirm shaft alignment before restoring air pressure.
