Compressed air motors –

energy-efficient strength.

PTM compressed air motors are robust and high-performance drives. Thanks to the efficient radial piston principle on which their drive is based, they are very economical at the same time. The small piston volumes inside the motors need a minimum of compressed air and simultaneously extract the highest power through expansion. Thereby, we reduce the consumption of compressed air by up to 90% compared to vane motors.

The construction of our motors is entirely mechanical, no electronics, no sensors. On the one hand, this makes their operation extremely safe with regard to the environmental conditions at their operation site. On the other hand, they are easily connected and operable within just a few minutes, without having to use any additional devices or the need to hire a specialist like an electronics technician.
Despite their high torque, the motors are small and compact. They can be integrated space-savingly in every application.

To meet the requirements of different areas of application and sectors, we developed our motor in six different versions:
