Gast 2AM-NRV-90 Air Motor

Description

The 2AM-NRV-90 is the “smooth-running” specialist of the 2AM NEMA family. By doubling the number of vanes from four to eight, the motor minimizes the “pulsing” effect (torque ripple) common in pneumatic motors. This results in more consistent power delivery and higher starting torque, which is critical when the motor must begin rotating under a heavy load or at very low RPM.

Like all Gast air motors, it is inherently Explosion Proof. The expansion of compressed air through the motor naturally cools the cast-iron housing, allowing it to operate in ambient temperatures up to 121°C (250°F) where electric motor insulation would fail.

GAST

Since 1921, Gast Manufacturing, Inc. has been a leader in the design and manufacturing of quality air-moving products. We specialize in offering cost effective solutions for a wide variety of industries including industrial manufacturing, healthcare, and environmental cleanup applications.

Features

8-Vane Smoothness: Provides superior control and smoother rotation at low RPM (300–800 range) compared to 4-vane models.
NEMA 56C Mounting: Features a standard C-face flange and a 5/8″ (0.625 in) keyed shaft, making it a “drop-in” replacement for standard small-frame electric motors.
Reversible Operation: A 4-way control valve allows for instant reversal of rotation, even while the motor is under load.
Variable Speed: Easily adjusted from 300 to 3,000 RPM by regulating the air pressure or flow volume.
Stall-Safe: Unlike electric motors, this unit can be stalled indefinitely without damage, overheating, or risk of fire.
ATEX & CE Certified: Approved for use in Group II, Category 2 (Gas & Dust) hazardous environments.

Applications

Precision Agitators: Ideal for mixing paints, inks, or chemical solutions where a steady, non-pulsing rotation is required.
Hazardous Area Winches: Providing reliable, smooth pulling power for small loads in refineries or mines.
Conveyor & Feed Drives: Powering small transport lines that require frequent starts/stops or very slow, consistent travel speeds.
High-Heat Material Handling: Operating near industrial ovens or furnaces where electronic components would melt.
Laboratory Equipment: Used in automated testing rigs where pneumatic safety and precise speed control are required.
