A reversible, 5.2 HP (3.9 kW) rotary vane air motor featuring an 8-vane design and an IEC #72 (D90) metric flange mount. It is a rugged, non-electrical power source designed for variable speed applications in hazardous or high-temperature areas.
The 8AM-ARV-71 is the metric-spec variant of the 8AM family, utilizing 1/2″ BSP ports and an IEC D90 flange. The standout feature of this specific model is its 8-vane configuration. While 4-vane motors are standard, the 8-vane design provides better “inching” control, smoother low-speed operation, and more consistent torque output because there are more vanes capturing the air pressure at any given moment.
