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 motor. The PolyGearbox is used in manually-managed or climate-managed ventilation and display systems in poly Gear motors for Greenhouse greenhouses. The quick and easy-to-installEP PolyGearbox is rainproof and windproof. The PolyGearbox has a high protection class (IP65) and can be used in an ambient temperature of 0-60 °C.
The low-noise PolyGearbox includes a gearwheel transmission and a worm wheel transmission, which are integrated within an aluminium precision housing. The self-braking worm wheel transmission ensures that the drive shaft is certainly locked when the decrease gearbox is not running. The fully sealed reduction gearbox has an growth chamber with a diaphragm to keep the gear essential oil at a minimal pressure under all conditions, even at high temperatures. Thanks to the use of an expansion chamber, the PolyGearbox can be installed in any placement. There are no restrictions, 
because there is no need for a bleed plug. The sealed decrease gearbox keeps the apparatus oil of the PolyGearbox in ideal condition because of its entire operating lifetime. The PolyGearbox is ideal for discontinuous use, operating course s3-30%, with a maximum activation time of 25 minutes.
The PolyGearbox reduction gearbox has an FT85 motor assembly flange, on to which the right IEC standard motor can easily 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 change system is installed within an built-in chamber and is certainly enclosed by an impact-resistant plastic cover. The limit switch system is obtainable and simple to adjust. The limit change system’s maximum switching range is certainly 40 or 64 revolutions of the drive shaft. The cabling is connected 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.
