In these times of rising costs, companies are increasingly reliant on pre-processing in automation. Even in the food industry automated production processes have gained in significance - hygiene is of equal importance as efficiency for the mechanical processing of foodstuffs. Whether for the production of fruit juice drinks or the preparation of kebab skewers, the handling of flour, the cutting of dough or the use of packaging machines, air motors are the perfect solution for all these varied drive applications.

High quality stainless steel air vane motors are especially suited to these challenging applications. DEPRAG SCHULZ GMBH u. CO. is an international leading supplier of air motors, automation, screwdriving technology and air tools. The DEPRAG engineers have spent decades developing and continuously improving their pneumatic motors.

Their ADVANCED LINE motor series provides systems engineers with quality stainless steel drives which combine many beneficial features. The robust, sealed design of their external parts in non-corrosive top quality stainless steel means that the vane motors are predestined for use in the food industry. The smooth surfaces are easy to clean and the drives repel steam and cleaning agents. The air motors are completely sealed, air cannot leak out and dirt cannot penetrate. The seal is so good that the air motor can even be used underwater. The motor does not even need a special housing. The motor spindle also withstands chemical cleaning agents and has a particularly long-life radial shaft sealant ring.

There are many advantages in using this pneumatic motor as a drive. The main benefit is the power density. Depending on the version it has a fifth of the mass of a normal electric motor or a third of its size. The air motor provides almost constant power over wide torque ranges.

The motor works along a simple principle. The compressed air generated by a compressor rotates the air motor. This functions in a vane motor by the rotor running within an off-centre cylinder. There are vanes in the slots of the rotor which are pressed against the outer cylinder wall by centrifugal force. Working chambers are created for the expanding compressed air. It is this expansion of the compressed air which is changed into kinetic energy and the rotation begins.
