The EP-45 motor gearboxes are maintenance-free, compact drive units for operating ventilation, display and flap MOTOR WORM GEARBOXES FOR GREENHOUSE GW80 CHAIN COUPLING ventilation systems in greenhouses and livestock houses. The EP-45 electric motor gearboxes are created to work at ambient temperature ranges between 0 and 60 °C.
All EP-45 engine gearboxes feature a self-braking worm equipment transmission. The EP- motor gearbox’s self-braking worm gear transmission ensures that the result shaft is certainly braked when the drive device is stopped. The mixture of carefully matched 
pinion and worm reductions results in a very quiet mechanical transmission.
The EP-45 motor gearboxes include a patented integrated linear limit-switch system with duty and safety switches having excellent switching precision. The utmost switching range of the limit-switch program compatible 97 revolutions of the drive shaft. The optional RPU PositioningUnit accurately monitors the current placement of a drive program and transmits this data back again to your climate computer or controller. This position feedback may also be achieved using an installation set with a potentiometer.
