The Automatic Vent Opener was designed to automatically control the temperature and humidity levels and provide additional ventilation when needed, making gardening easier. As the air in the greenhouse warms, the vent gradually 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 press a piston, which raises the windows, as the surroundings gets warmer, then agreements as it cools, closing with the usage of a springtime and resetting the piston. All you need to do is usually to install it on your own roof vent home window and it instantly starts operating. The Automatic Vent Opener operates without the use of electricity and is compatible with all Palram greenhouse versions only. The solar powered Vent Opener will start to open as temperature ranges inside your greenhouse reach 68 degrees F with full-open at 80 degrees. It installs quickly and easily and will provide care-free ventilation.
Ingenious temperature-delicate device that automatically opens and closes coldframe lids, greenhouse windows and actually skylights. Works throughout the day and maintain a constant interior climate, something not possible to accomplish by manual adjustments.
Requires no batteries or electricity.
It can be adjusted to start opening between 60-77°F. Fully open at 86-90°F. Fully closed at 55°F.
Strongly recommended for almost all our glazed season extenders since it dramatically increases plant growth.
The hydraulic cylinder includes a 1 year warranty. The common duration of the cylinder is certainly 5-10 years, although some can last up to 20 years.
Screw straight into polycarbonate panels, wood, or metal frames. THE TYPICAL Vent Opener can open a hinged windowpane or vent weighing just as much as 32 lb. For larger panes use the stronger Gigavent with all metal building, to lift up to 65 lbs.
Note from the manufacturer: Recommended to lubricate the piston rod yearly, this will help extend the lifetime of the hydraulic cylinder. Don’t use solid grease, as dust particles “glues” quickly onto the piston rod and can harm the rubber. Also don’t forget to unlock the vent in the wintertime if Automatic Greenhouse Vent leaving the vent openers installed. Even a weak winter sun can temperature the hydraulic cylinder sufficiently to create it start pressing the piston rod outwards.
