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.

Gigavent Vent Opener Installation Manual

Overall Customer Rating of 1 Reviews:

Best Vent Opener on the Market

Rating:
Just installed 2 Gigavent openers in my greenhouse. Both vents are 2 ft x 8 ft. The Gigavent has worked well. Installation was a bit of a chalenge but with a piece of 2.5 in angle aluminum I was able to make brackets that made installation easier. It appears that the Gigavent requires 2 surfaces to mount on which are 90 degrees from the opening direction of the vent as shown in the instructions. It would be nice to have installation on at least one surface which is along the surface of the vent. The aluminum angle piece solves this problem. Overall I am pleased with the Gigavent. It replaced a Bayliss unit which is a little more than half the price but basically a piece of junk. The Bayliss worked for a couple of years then gave out and even a cylinder replacement only allowed 1 more year of spotty performance. The action of the Gigavent is much smoother and opening and closing is silent, unlike the Bayliss.
