The RW 400 engine reducers are maintenance-free, compact drives for ventilation, screen and hoist systems in greenhouses or stables.

All RW400 engine reducers are equipped with a self-propelled worm gear. This transmission guarantees a locked position of the drive shaft when the drive is stopped. The combination of tandem gearboxes and worm gear transmission matched to a low-noise drive.

The RW400 engine reducers are equipped with the patented RSU linear end switch system with operating and security switches and high switching accuracy. The maximum switching range of the terminal switching system is 86 rotations of the drive shaft. With the optional RPU Positioning Unit, it is possible to accurately report the positions of a drive system to a (climate) computer. Recall of positions is also possible by using a potentiometer installation kit.

The RW400 engine reducers are made of graphite gray powder coating and comes with fastening bolts and spring rings.
