Gast 2AM-ACC-88 Air Motor

A reversible, 0.5 HP (0.37 kW) rotary vane air motor featuring an 8-vane design and a standard Hub Mount. It is an intrinsically safe, cool-running power source optimized for precision mixing, dosing, and steady-speed laboratory drives.

Description

The 2AM-ACC-88 is the “smooth-running” specialist of the 2AM family. By doubling the number of vanes from four to eight, the motor significantly reduces “torque ripple” (the pulsing effect common in pneumatic motors). This allows the motor to maintain consistent power delivery and higher starting torque, even when operating at the lower end of its speed range.

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 safely in ambient temperatures up to 121°C (250°F) where electric motor insulation would fail.

Features

  • 8-Vane Smoothness: Provides superior “inching” control and smoother rotation at low RPM (300–800 range) compared to 4-vane models.
  • Standard Hub Mounting: Features a precision-machined hub and a 1/2″ (0.500 in) keyed shaft, making it easy to mount via a simple clamp or bracket.
  • 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.
  • Compact Power: Delivers a robust half-horsepower in a frame weighing only 5 lbs (2.3 kg).

Applications

  • Precision Agitators: Ideal for mixing paints, inks, or chemical solutions where a steady, non-pulsing rotation is required.
  • Laboratory Stirrers: Used in automated testing rigs and centrifuges where precise speed control is mandatory.
  • Dosing & Metering: Powering small pumps in refineries or chemical processing plants where spark-free operation is a requirement.
  • Medical & Pharmaceutical Equipment: Integrated into devices where pneumatic safety and a compact hub-mount are required.
  • High-Heat Material Handling: Operating near industrial ovens or furnaces where electronic components would be destroyed by heat.
