This is the strongest vent opener we offer. It has a hydraulic cylinder which provides superior protection in windy areas. Opening temperature can be adjusted from 63° F to 77° F and maximum opening of 18" is reached at approximately 20° F above opening temperature. Gigavent cylinder can be installed in many different positions for maximum mounting flexibility. This model is too large for use with all of our greenhouses except some of the Cross Country models.

How does a Greenhouse Autovent work?
A strong metal tube contains a mineral wax which expands with heat. This pushes a piston which opens the auto vent via a balanced linkage. As the temperature drops, the wax shrinks and a strong spring closes the vent and resets the piston.
