This vent opener has been designed to control temperature and humidity levels and provide additional ventilation when needed, making gardening easier. As the air inside the greenhouse warms up, the vent gradually opens to allow the right amount of air into the greenhouse and closes as the temperature cools.
The vent arm was designed with a metal cylinder containing wax that expands when heated to push a piston, which raises the window as the air warms, then contracts as it cools, closing with a spring and resetting the piston. All you have to do is install it on your roof vent window and it automatically starts working.
The automatic vent opener works without the use of electricity and is compatible with all Palram - Canopia greenhouse models.
