The Worm drive is a chain-driven unit ideal for operating ventilation systems and energy screens without electricity. It’s especially useful for elevated side vents that can’t be reached with a standard crank, and for small to medium greenhouse, barn, or hall installations.

Its rugged design with KST chain wheel and guide ensures durability and reliability. The 1:16 gear ratio delivers 70 Nm of torque, and the 2-meter chain provides ample reach.

Engineered to withstand greenhouse conditions, the system is low-maintenance and installs directly onto the drive shaft for quick setup.
