Rack and Pinion Vents

Rack & Pinion Ventilation Systerm

a

The Rack & Pinion Ventilation System is often used for ventilation in multi-span greenhouse. The system has the character of steady performance, safty and reliablity.

In this system, the gear motor drives the pinion by its drive shaft, and the pinion meshes the rack to achieve its straight reciprocating movement.

One end of the rack connects to the supporter of the ventilation window to achieve the open and close of the ventilation window.
