The EP PolyGearbox (RPG) is a concise and lightweight reduction gearbox with a built-in limit switch system that is ideal for assembly of a locally available electric electric motor. The PolyGearbox is utilized in manually-managed or climate-controlled ventilation and display 
screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox can be rainproof and windproof. The PolyGearbox has a high protection course (IP65) and can be used in an ambient temperature of 0-60 °C.
The low-noise PolyGearbox has a gearwheel transmission and a worm wheel transmission, which are integrated in an aluminium precision Gear motors for Greenhouse housing. The self-braking worm wheel tranny means that the drive shaft is locked when the reduction gearbox is not running. The completely sealed reduction gearbox has an growth chamber with a diaphragm to keep the gear essential oil at a low pressure under all conditions, even at high temps. Thanks to the use of an growth chamber, the PolyGearbox could be installed in any placement. There are no limitations, since there is no dependence on a bleed plug. The sealed decrease gearbox keeps the gear essential oil of the PolyGearbox in ideal condition because of its entire operating life time. The PolyGearbox is ideal for discontinuous use, working class s3-30%, with a maximum activation period of 25 minutes.
The PolyGearbox reduction gearbox has an FT85 motor assembly flange, to which the right IEC standard motor can certainly be installed (EN 50347).
The PolyGearbox includes a rotating limit switch system with operating switches and circuit breakers (NC contacts) for turning off at the end positions. The limit switch system is installed within an included chamber and can be enclosed by an impact-resistant plastic material cover. The limit change system is accessible and simple to adjust. The limit change system’s optimum switching range is certainly 40 or 64 revolutions of the drive shaft. The cabling is linked in spring-clip connections. The PolyGearbox comes with an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
