The Automatic Vent Opener was designed to automatically control the temperature and humidity amounts and offer additional ventilation when needed, making gardening easier. As the air flow in the greenhouse warms, the vent gradually opens to allow the correct amount of air flow in to the greenhouse and closes when the temperature cools. The vent arm was designed with a metallic cylinder that contains wax which expands when heated to drive a piston, which raises the home window, as the surroundings gets warmer, then contracts since it cools, closing with the Automatic Greenhouse Vent utilization of a springtime and resetting the piston. All you need to do is certainly to install it on your own roof vent windowpane and it automatically starts operating. The Automatic Vent Opener functions without the use of electricity and works with with all Palram greenhouse models only. The solar run Vent Opener will start to open as temps within your greenhouse reach 68 degrees F with full-open at 80 degrees. It installs efficiently and will provide care-free ventilation.

Requires no batteries or electricity.
It can be adjusted to begin opening between 60-77°F. Fully open at 86-90°F. Fully closed at 55°F.

Note from the maker: Recommended to lubricate the piston rod yearly, this will help extend the lifetime of the hydraulic cylinder. Avoid solid grease, as dust particles “glues” quickly onto the piston rod and can harm the rubber. Also do not forget to unlock the vent in the wintertime if leaving the vent openers installed. Even a weak winter sun can warmth the hydraulic cylinder sufficiently to create it start pressing the piston rod outwards.
