Gast 1AM-NCW-14 Air Motor

A clockwise-rotation, 0.33 HP (0.25 kW) rotary vane air motor featuring a 4-vane design and a NEMA 42C flange mount. It is an intrinsically safe, high-speed power source optimized for North American OEM machinery and specialized laboratory equipment where reversal is not required.

Description

The 1AM-NCW-14 is built for high-RPM applications, capable of reaching speeds up to 10,000 RPM. By utilizing a single-direction (Non-reversible) internal porting design, it achieves better air consumption efficiency and simplified plumbing compared to reversible models. Because it is powered entirely by compressed air, it is inherently ATEX and CE certified for hazardous locations (Group II, Cat 2), as it cannot produce an electrical spark.

A major technical advantage of the 1AM series is its thermal resilience. As compressed air expands through the motor to create motion, it naturally absorbs heat, keeping the cast-iron housing cool to the touch even in ambient temperatures up to 121°C (250°F).

Features

  • NEMA 42C Mounting: Features a compact C-face flange and a 3/8″ (0.375 in) keyed shaft, allowing it to bolt directly to small-frame gear reducers or precision pumps.
  • 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 operation and air-line setup.
  • Variable Speed: RPM can be precisely controlled from 500 to 10,000 RPM by simply adjusting the air pressure or flow volume.
  • Explosion Proof: Non-electrical design is safe for chemical plants, laboratories, and areas with combustible dust or vapors.
  • Stall-Safe: Unlike electric motors, the 1AM-NCW-14 can be stalled indefinitely without damage, overheating, or risk of fire.
