Gear Motor for Greenhouse Ventilation

The LG 120 is a compact, high-quality gear motor, specially designed for greenhouse and glasshouse conditions. The design of the gear motor makes it ideal for either rack and pinion systems for ventilation, or automatic screen systems. The LG 120 is relatively easy to install because of its compact size and unique design of having the input shaft parallel to the electric motor.

• Self-locking worm gear secures the vent or screen when the power is cut off.
• Standard torque of 120 N-m and 3.45 RPM. (at 44 W)
• Models available from 0.28 RPM to 69 RPM.
• "Right" or "Left" models available.
• Ball bearings minimize noise.
• Electric motor conforms to the DIN standard.
• The closed, maintenance-free gearbox is made from cast light alloy, which gives the LG 120 a low net weight relative to its performance.
