Gast 2AM-NCC-43A Air Motor

A clockwise-rotation, 0.5 HP (0.37 kW) rotary vane air motor featuring a 4-vane design and a standard Hub Mount. It is an intrinsically safe, cool-running power source optimized for North American OEM machinery and specialized laboratory equipment.

Description

The 2AM-NCC-43A is engineered for simplicity and efficiency. By utilizing a single-direction (Non-reversible) internal porting design, it often achieves slightly better air consumption metrics than reversible models. Because it is powered entirely by compressed air, it is inherently ATEX and CE certified for use in explosive atmospheres (Group II, Cat 2), as it cannot produce an electrical spark.

A major technical advantage of this motor is its thermal resilience. As compressed air expands through the motor to create motion, it naturally absorbs heat. This allows the 2AM-NCC-43A to operate in ambient temperatures as high as 121°C (250°F), which would cause standard electric motor insulation to fail.

Features

  • Standard Hub Mount: Features a precision-machined hub and a 1/2″ (0.500 in) keyed shaft, allowing for easy mounting via a simple clamp or bracket.
  • 4-Vane Configuration: The industrial standard for balanced performance, providing high-speed stability and efficient air consumption.
  • Clockwise Rotation: Optimized for applications where reversal is not required, ensuring simplified plumbing and operation.
  • Variable Speed: RPM can be precisely controlled from 300 to 3,000 RPM by simply adjusting the air pressure or flow volume.
  • Explosion Proof: Non-electrical design is safe for chemical plants, refineries, and areas with combustible dust.
  • Stall-Safe: Unlike electric motors, the 2AM-NCC-43A can be stalled indefinitely without damage, overheating, or risk of fire.
