The Automatic Vent Opener was designed to automatically control the temperature and humidity amounts and provide additional ventilation when needed, making gardening easier. As the atmosphere inside the greenhouse warms, the vent gradually opens to allow 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 press a piston, which raises the home window, as the atmosphere gets warmer, then agreements as it cools, closing with the use of a springtime and resetting the piston. All you have to to do can be to install it on your roof vent screen and it instantly starts functioning. The Automatic Vent Opener works without the use of electricity and works with with all Palram greenhouse models only. The solar driven Vent Opener will start to open as temperatures inside your greenhouse reach 68 degrees F with full-open at 80 degrees. It installs quickly and easily and will provide care-free ventilation.

Note from the manufacturer: Suggested to lubricate the piston rod annual, this will help extend the duration of the hydraulic cylinder. Don’t use solid grease, as dirt particles “glues” quickly onto the piston rod and may damage the rubber. Also do not forget to unlock the vent in the winter if leaving the vent openers installed. A good weak winter sun can temperature the hydraulic cylinder sufficiently to create it start pressing the piston rod outwards.
