The EP PolyGearbox (RPG) is a concise and lightweight reduction gearbox with a limit switch system that is ideal for assembly of a locally available electric engine. The PolyGearbox can be used in manually-managed or Gear motors for Greenhouse climate-controlled ventilation and screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is usually rainproof and windproof. The PolyGearbox has a high protection class (IP65) and can be utilized 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 housing. The self-braking worm wheel tranny means that the drive shaft is certainly locked when the reduction gearbox isn’t running. The completely sealed reduction gearbox comes with an growth chamber with a diaphragm to keep the gear oil at a minimal pressure under all conditions, even at high temperature ranges. Thanks to the usage of an expansion chamber, the PolyGearbox could be installed in any placement. There are no restrictions, 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 suitable for discontinuous use, operating class s3-30%, with a maximum activation time of 25 minutes.

The PolyGearbox reduction gearbox has an FT85 motor assembly flange, to which the right IEC standard electric 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 switch system is installed within an built-in chamber and is definitely enclosed by an impact-resistant plastic-type material cover. The limit switch system is obtainable and simple to adjust. The limit change system’s maximum switching range can be 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.
