Air motors

The pneumatic motor, also called air motor, vane motor, rotary pneumatic motor or pneumatic rotary actuator, is a particular type of motor designed to create mechanical movement by exploiting the expansion of strongly compressed air.


The pneumatic motors / air motors / pneumatic rotary motor / pneumatic rotary actuator that we offer in our sales range are "vane".

The vane motors are composed of a grooved rotor, on which blades with spring compensation system are installed, which rotate eccentric inside a chamber having a pneumatic inlet and exhaust.

The thrust of compressed air on the vanes and the centrifugal force generated create a circular motion that is transmitted to the shaft; the exhausted air is continuously conveyed to the exhaust.

Our pneumatic motors / air motors / vane motors / pneumatic rotary motor / pneumatic rotary actuator develop an equivalent power between 0.35 ÷ 7.0 kW and can be substituted for electric motors of equal output ensuring a smaller footprint and weight.

Other advantages of air motors / air motors / vane motors / air rotary motor / pneumatic rotary actuator over electric ones are as follows:

  • Possibility of being blocked during operation or being subjected to overloads without overheating or suffering other damage;
  • Possibility of being started / stopped repeatedly in an unlimited manner;
  • Possibility of easily adjusting the rotation speed and the torque delivered, acting on the pressure and the flow rate of the compressed air supply;
  • Possibility of easily reversing the direction of rotation;
  • Possibility to work without problems in very hot (135 ° C) dusty and humid environments;
  • Possibility to work in potentially explosive atmospheres - ATEX ZONE 1 (Ex IIGD Ex IIC T6 Gb - Ex IIGD Ex h IIIC T85degC Db);
  • Ability to manage ramp starting using a proportional valve;
  • They require minimal maintenance;
  • Ability to be mounted in any position ;
  • Possibility of being made entirely of stainless steel;
  • Possibility of working and dry;

Pneumatic motors / air motors / vane motors / rotary pneumatic motor / pneumatic rotary actuator can be used to motorize any equipment that requires motion transmission, the main ones are listed below:

  • agitators and mixers;
  • hydraulic pumps;
  • tools (screwdrivers, core drills, miter saws, etc.);
  • conveyor belts; < / li>
  • hoists, winches and winches;
  • winders / unwinders of cables, ropes, tapes and pipes;
  • shredders;
  • packaging machines ;
  • tippers;
  • sieves and vibrating screens;
  • wheel balancers and tire disassemblers;
  • bulkheads and shutters;
  • < li> tensioners and strapping machines;
  • fans;

If it is necessary to reduce the speed, or to increase the torque of a pneumatic motor / air motor / vane motor / rotary pneumatic motor / pneumatic rotary actuator, it is possible to couple it to a reducer so as to obtain a pneumatic gearmotor.

There are many types of gearboxes but those most used in combination with pneumatic motors are coaxial, planetary and worm screw type.
