The compact piston air motors high torque is die t the power transmission of the pistons along the large external, diameter of the curve.

The friction connected with the travel along the curve is low due to the installation of rollers at the tip of the pistons. This results in high lifetime of the drive.

Because of the use of pistons, low internal friction and negligible internal air leakage the air consumption of the motor is extremely low.

When compared with a vane motor at the same speed and torque an air consumption reduction of 80 % is achieved.  125-l/min compact piston air motor to 600-l/min-vane motor.

High torque at low speed of rotation

Very low air consumption

Low noise emission

Long lifetime


Able to run without lubrication

Noise emissions are determined according to the noise measuring standards ISO 11202 and within the frame of the ISO 11200 standards.

The measured noise levels are 74dB for the RM015 and 76 dB for the RM025. The pneumatic drive this fulfills the noise regulations without requirement for ear protection devices.
