Good things come to those who wait, but time costs money – especially concerning maintenance work, where in fact simple solutions can be employed to speed things up. The engineers at DEPRAG SCHULZ GMBH u. CO. have therefore developed the BASIC LINE air vane motor with a particularly attractive price to performance ratio. Their patented vane exchange system is unique throughout the world and is an enormous time-saver. In just a few movements the vanes can be replaced. Long periods where the system is out of action are completely avoided as vane exchange on the service friendly BASIC LINE air motors can be carried out in situ directly on the machine without the need for disassembly.

Even untrained personnel can quickly replace worn vanes using only a screwdriver and tweezers. Once the cylinder screws on the rear bearing cover have been loosened and the rollers removed, replacement is easy. The complete maintenance is finished in a few minutes, much quicker than exchanging the whole motor in the system. The patented vane exchange system considerable reduces not only the maintenance time compared to previously popular air motors but also saves production time.

Wear on the vanes is a result of the working principle of the motors, the rotor turning in the off-centre cylinder. The vanes, situated in slots in the rotor, are pressed against the wall of the rotor by centrifugal force and build working chambers. The expansion of compressed supply air changes pressure energy into kinetic energy and the motor rotates. Friction is therefore created between the vanes and the rotor cylinder walls and after many hours of operation vanes become worn.

Lubricated operation improves the total lifespan of an air motor. To reach the optimum level of power and lifespan use 1-2 drops of oil per 1m³ air consumption. The supply air quality should correspond with the standard ISO 8573-1 (see image). However all BASIC LINE motors can also be operated oil-free. Unlubricated operation means shorter maintenance intervals and also a 10-20% loss of power must be calculated for the motor.
