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 air flow within the greenhouse warms, the vent steadily opens to enable the correct amount of ventilation into the greenhouse and closes when the temperature cools. The vent arm was designed with a metallic cylinder containing wax which expands when heated to push a piston, which raises the windowpane, as the air gets warmer, then agreements as it cools, closing with the use of a springtime and resetting the piston. All you need to do is definitely to install it on your roof vent home window and it immediately starts working. The Automatic Vent Opener works without the usage of electricity and works with with all Palram greenhouse versions only.

It installs efficiently and will provide care-free ventilation.
