Our powerful pneumatic motors offer interesting alternatives for drive- and control tasks for all industry areas. Click here to learn more about the functionality of a vane motor. DEPRAG also offers customized air motors for individual applications; those air motors are based on a modular construction system and a comprehensive standard catalog.
This modern and compact BASIC LINE air motor offers an especially attractive price-to-performance ratio due to his modular design and further advantages such as; high power density, small size, robustness, ATEX-certification for the use in explosion-proof areas.
When used in a dry environment and under standard stationary production operation, then the pneumatic motor made from cast-iron material is the best choice. Get advice from our engineers now.
This air motor series is available in 3 power classes:
200 W – 400 W – 600 W – 900 W – 1.2 kW
The pneumatic motor remains where it is installed. This feature is an enormous time saver.
Low Maintenance: After loosening the cap-screws and removing the rollers, the vanes may be removed using a tweezers. Afterwards the new vanes may be installed in reverse order.
All air motors can be operated oil-free, without special measures.

ADVANCED LINE air motors
The ADVANCED LINE air motor made from stainless steel is used in areas where high hygiene requirements are necessary. This air motor is especially suited for the use in the food industry, medical industry, pharmaceutical industry and chemical industry, etc.
The ADVANCED LINE air motor is fully sealed and steam-resistant. It is even possible to operate this air motor under water (completely submerged).
All air motors are made from stainless steel and can also be used without lubrication with only a slight power loss of approx. 15%. Because of our flexible and modular system, we can offer a multitude of variation possibilities (for example differently designed drive spindles, etc.), at a very attractive cost-benefit ratio.
For the use in agitators or mixers, which have a very stringent hygiene requirement, we can offer our air motors with a high-torque gearing that is made from stainless steel as well.
Stainless steel air motor with integrated planetary gear
The vane motors of the ADVANCED LINE are especially compact drives for integration into handheld devices or industrial facilities. These high quality stainless steel motors are especially suitable for the Paper and Food Industries, for Chemical and Pharmaceutical Industries and also for application in Medical Technology. The ADVANCED LINE airmotor is fully sealed and can be operated without lubrication.
Available power classes:
20 W to 1.6 kW
High-torque air motor made from stainless steel
Our high torque air motors are stall-proof; for example the stall-torque of the motor 67X-517 is 600 Nm. This drive is especially well-suited for the use in industrial mixer and agitator facilities of the paint industry, the food industry of the pharmaceutical industry.
Available power classes:
285 W – 570 W – 860 W
Stainless steel air motor with integrated holding brake
DEPRAG stainless steel air motors with integrated holding brake are suitable for use in any application area due to their optimal size and design in which safety plays an important role. The integrated brake equipment can be controlled either via a separate control line or directly via the airmotor exhaust. If pressure drops in the line the brake is automatically activated.

Design and functional principle of a vane motor
Vane motors consist essentially of a rotor which revolves in an eccentrically offset perforation of the rotor cylinder. The vanes form working chambers, the volume of which increases in the turn direction. As the compressed air expands, the pressure energy subsequently transforms into kinetic energy, thereby producing the rotary motion.
Air motors that are designed to rotate in one direction only, have more rotational angle for the air to relax. Therefore the non-reversible vane motors reach a higher power output and higher speeds than reversible air motors.
