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