The Automatic Vent Opener was made to automatically Greenhouse Vent Opener control the temperature and humidity levels and offer additional ventilation when needed, making gardening easier. As the atmosphere within the greenhouse warms, the vent gradually opens to allow the right amount of ventilation in to the greenhouse and closes when the temperature cools. The vent arm was designed with a metal cylinder containing wax which expands when heated to push a piston, which raises the windows, as the surroundings gets warmer, then contracts as it cools, closing with the utilization of a spring and resetting the piston. All you need to do is usually to install it on your roof vent window and it automatically starts operating. The Automatic Vent Opener operates without the utilization of electricity and works with with all Palram greenhouse models only. The solar powered 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 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 not possible to accomplish 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 all our glazed season extenders because it dramatically enhances plant growth.
The hydraulic cylinder includes a 1 year warranty. The average duration of the cylinder is certainly 5-10 years, even though some can last up to 20 years.

Screw directly into polycarbonate panels, wooden, or metal frames. The Standard Vent Opener can open up a hinged window or vent weighing just as much as 32 lb. For bigger panes use the more powerful Gigavent with all metallic construction, to lift up to 65 lbs.

Note from the manufacturer: Recommended to lubricate the piston rod annual, 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 can harm the rubber. Also do not forget to unlock the vent in the wintertime if departing the vent openers installed. Even a weak winter sunlight can warmth the hydraulic cylinder sufficiently to make it start pressing 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 is 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 completely opened for usage of the interior.
