Compressed air motors –

energy-efficient strength.

With our compressed air motors, the radial piston principle is used in the most economical way. The small piston volumes inside the motors need a minimum of compressed air and simultaneously extract the highest power from the energy through expansion. Thereby, we reduce the consumption of compressed air by up to 90% compared to vane motors. To meet the requirements of different areas of application and sectors, we developed our motor in five different versions:
