Greenhouse Vent Opener

The Automatic Vent Opener was designed to automatically control the temperature and humidity levels and offer additional ventilation when needed, making gardening easier. As the surroundings in the greenhouse warms, the vent gradually opens to allow the correct amount of air flow into the greenhouse and closes when the temperature cools. The vent arm was designed with a metal cylinder containing wax which expands when heated to press a piston, which raises the window, as the air gets warmer, then contracts as it cools, closing with the use of a spring and resetting the piston. All you have to to do is usually to install it on your own roof vent home window and it instantly starts working. The Automatic Vent Opener works without the use of electricity and is compatible with all Palram greenhouse versions only. The solar driven Vent Opener will start to open as temps inside your greenhouse reach 68 degrees F with full-open at 80 degrees. It installs quickly and easily and can provide care-free ventilation.
Ingenious temperature-delicate device that automatically opens and closes coldframe lids, greenhouse windows and even skylights. Works during the day and maintain a continuous interior climate, something not possible to achieve by manual adjustments.

Requires simply no batteries or electricity.
It could be adjusted to start opening between 60-77°F. Fully open at 86-90°F. Fully closed at 55°F.
Strongly recommended for every our glazed Greenhouse Vent Opener season extenders because it dramatically increases plant growth.
The hydraulic cylinder comes with a 1 year warranty. The average duration of the cylinder is certainly 5-10 years, even though some can last up to 20 years.
