Gast 6AM-ARV-55 Air Motor

A reversible, 4 HP (3 kW) rotary vane air motor featuring a 4-vane design and a Metric IEC D80 flange. It is an intrinsically safe, cool-running pneumatic motor designed for variable speed applications in international industrial markets.

Description

The 6AM-ARV-55 is the metric-spec variant of the 6AM family, utilizing 1/2″ BSP ports and a 19 mm keyed shaft. The 4-vane design is the standard for high-speed efficiency and reliable operation. Because it is powered by compressed air, it is inherently ATEX and CE certified for use in explosive atmospheres (Group II, Cat 2), as it generates no electrical sparks.

A unique benefit of this pneumatic motor is its ability to operate in high-ambient temperatures (up to 121°C / 250°F). As the compressed air expands through the motor, it absorbs heat, keeping the cast-iron housing cool even under heavy continuous loads.

Features

  • IEC #72 D80 Flange: Features a metric mounting interface, making it a “drop-in” replacement for metric electric motors or for bolting directly to European-standard gearboxes.
  • 4-Vane Configuration: Optimized for high-speed performance and efficient air consumption.
  • Variable Speed & Torque: RPM can be precision-controlled from 300 to 3,000 RPM by adjusting the air pressure or flow volume.
  • Explosion Proof: Non-electrical design is safe for chemical plants, refineries, and areas with combustible dust.
  • Instantly Reversible: A 4-way control valve allows the motor to switch rotation directions instantly, even under full load.
  • Stall-Safe: Will not burn out if overloaded; the motor simply stops and resumes once the load is removed.
