The EP PolyGearbox (RPG) is a compact and lightweight reduction gearbox with a limit switch system that is ideal for assembly of a locally available electric motor. The PolyGearbox is utilized in manually-managed or climate-controlled ventilation and screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is certainly rainproof and windproof. The PolyGearbox includes a high protection course (IP65) and can be utilized within 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 tranny means that the drive shaft is locked when the reduction gearbox is not running. The completely sealed reduction gearbox comes with an growth chamber with a diaphragm to keep carefully the gear oil at a low pressure under all circumstances, even at high temperature ranges. Thanks to the use of an growth chamber, the PolyGearbox can be installed in any placement. There are no limitations, since there is no need for a bleed connect. The sealed decrease gearbox keeps the apparatus oil of the PolyGearbox in optimum condition for its entire operating lifetime. The PolyGearbox is ideal for discontinuous use, operating course s3-30%, with a maximum Gear motors for Greenhouse activation time of 25 minutes.
The PolyGearbox reduction gearbox comes with an FT85 motor assembly flange, to which the right IEC standard engine 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 change system is installed in an integrated chamber and is enclosed by an impact-resistant plastic material cover. The limit change system is obtainable and easy to adjust. The limit switch system’s maximum switching range can be 40 or 64 revolutions of the drive shaft. The cabling is linked in spring-clip connections. The PolyGearbox has an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
