ATEX certification supports motor use in explosive environments

The P1V-A Series of reversible air motors from Parker Hannifin has been expanded with additional power ratings, including models with ATEX certification that is well suited for use in explosive environment applications.

The new extended family of P1V-A Series of air motors features painted cast iron motor housings and sealed components to enable reliable operation in challenging, damp, dirty environments. The range contains six different sizes with power ratings ranging from 1,600-18,000W.

The motors can be supplied either in basic form or with built-in gearboxes. Three types of gearboxes - planetary, helical or worm gears - are available for selection depending on the type of rotation and torque required in the application. A combination of face and base mounting options offer additional flexibility to system designers.

All of Parker’s P1V-A pneumatic air motors are equipped with spring loaded vanes as standard - this supports very good starting and low speed running characteristics. The simple, rugged construction of the motors makes them vibration, heat and impact resistant as well as enhancing reliability, speed and ease of servicing.

Air motors are better suited to some rotary power transmission applications than electric motors, especially when operating in harsh industrial environments. With their comparatively small dimensions and fewer moving parts, air motors are self-cooling and do not pose a sparking hazard. Unlike their electrical counterparts, they can be stopped and started repeatedly and even loaded until they stall without incurring any damage.

ATEX-certified versions for use in environments with an explosive atmosphere are available for four basic models without gearboxes – 1,600, 3,200, 5,000 and 6,000W. The ATEX certified motors can operate at ambient temperatures in explosive environments ranging from -20°C to +40°C and can withstand pressures spanning four to six bar.
