Gast 2AM-NCW-7B Air Motor

Description

the 2AM-NCW-7B is built for reliability. by utilizing a single-direction (non-reversible) internal porting design, it typically achieves better air consumption efficiency and a simpler plumbing setup than reversible models. because it is powered entirely by compressed air, it is inherently atex certified for hazardous locations, as it cannot produce an electrical spark.

a major technical advantage is its thermal profile. as compressed air expands through the motor to create motion, it naturally absorbs heat. this allows the motor to run cool to the touch even in ambient temperatures up to 121°c (250°f), making it far more resilient than electric motors in high-heat zones.

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

hub mounting: features a precision-machined hub and a 1/2″ (0.50 in) keyed shaft, allowing for flexible mounting via a simple clamp or custom bracket.
4-vane configuration: the industrial standard for balanced performance, providing high-speed stability and efficient air consumption.
clockwise rotation: optimized for one-way applications, ensuring simplified operation and air-line plumbing.
variable speed: speed can be precisely controlled from 300 to 3,000 rpm by simply adjusting the air pressure or flow volume via a regulator.
explosion proof: non-electrical design is safe for chemical plants, refineries, and areas with combustible dust or vapors.
stall-safe: unlike electric motors, the 2AM-NCW-7B can be stalled indefinitely without damage, overheating, or risk of fire.
