The Automatic Vent Opener was made to automatically control the temperature and humidity levels and offer additional ventilation when needed, making gardening easier. As the atmosphere in 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 steel cylinder that contains wax which expands when heated to press a piston, which raises the window, as the air flow gets warmer, then contracts as it cools, closing with the utilization of a spring and resetting the piston. All you have to to do is to install it on your own roof vent screen and it immediately starts working. The Automatic Vent Opener operates without the utilization of electricity and is compatible with all Palram greenhouse versions only. The solar driven Vent Opener will begin 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-sensitive device that automatically opens and closes coldframe lids, greenhouse windows and even skylights. Works during the day and maintain a continuous interior climate, something impossible to accomplish by manual adjustments.
