The Automatic Vent Opener was made to automatically control the temperature and humidity levels and provide additional ventilation when needed, making gardening easier. As the air within the greenhouse warms, the vent steadily opens to enable the correct amount of air flow into the greenhouse and closes when the temperature cools. The vent arm was made with a steel cylinder containing wax which expands when heated to drive a piston, which raises the screen, as the air gets warmer, then contracts since it cools, closing with the utilization of a springtime and resetting the piston. All you have to to do is certainly to install it on your own roof vent screen and it instantly starts functioning. The Automatic Vent Opener functions without the usage of electricity and works with with all Palram greenhouse versions only. The solar powered Vent Opener will begin to open as temperature ranges within 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 actually skylights. Works during the day and maintain a continuous interior climate, something impossible to attain by manual adjustments.

Requires no batteries or electricity.
It could be adjusted to start opening between 60-77°F. Fully open at 86-90°F. Fully closed at 55°F.
Strongly recommended for most our glazed season extenders since it dramatically increases plant growth.
The hydraulic cylinder includes a 1 year warranty. The average duration of the cylinder is definitely 5-10 years, even though some can last up to twenty years.

Screw straight into polycarbonate panels, wooden, or metal frames. THE TYPICAL Vent Opener can open a hinged windowpane or vent weighing as much as 32 lb. For larger panes use the more powerful Gigavent with all steel construction, to lift up to 65 lbs.

Note from the maker: Suggested 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” very easily onto the piston rod and will harm the rubber. Also do not forget to unlock the vent in the winter if leaving the vent Automatic Greenhouse Vent openers set up. A good weak winter sun can warmth the hydraulic cylinder sufficiently to make it start pushing the piston rod outwards.
This solar vent control will open and close vents, in your solar gem greenhouse. It features two closing springs for extra power. The solar vent opener may be the only solar-powered control with a quick-release mounting bracket. Just grasp the “clutch” arm and squeeze for easy detachment. This allows vent to be fully opened for usage of the interior.
