Greenhouse Vent Opener

The Automatic Vent Opener was made to automatically control the temperature and humidity amounts and offer additional ventilation when needed, making gardening easier. As the air flow within the greenhouse warms, the vent steadily opens to allow the right amount of ventilation into the greenhouse and closes when the temperature cools. The vent arm was made with a metal Greenhouse Vent Opener cylinder containing wax which expands when heated to push a piston, which raises the windows, as the surroundings gets warmer, then agreements since it cools, closing with the use of a springtime and resetting the piston. All you have to to do is to install it on your roof vent window and it automatically starts operating. The Automatic Vent Opener functions without the utilization of electricity and is compatible with all Palram greenhouse models 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 can provide care-free ventilation.
Ingenious temperature-delicate device that automatically opens and closes coldframe lids, greenhouse windows and even skylights. Works during the day and maintain a continuous interior climate, something difficult to accomplish by manual adjustments.

Requires no batteries or electricity.
It could be adjusted to start opening between 60-77°F. Fully open up at 86-90°F. Fully closed at 55°F.
Strongly recommended for most our glazed season extenders since it dramatically boosts plant growth.
The hydraulic cylinder includes a 1 year warranty. The common duration of the cylinder is certainly 5-10 years, even though some can last up to 20 years.

Screw straight into polycarbonate panels, wood, or metal frames. THE TYPICAL Vent Opener can open a hinged home window or vent weighing just as much as 32 lb. For larger panes use the stronger Gigavent with all metal structure, to lift up to 65 lbs.

Note from the maker: Suggested to lubricate the piston rod yearly, this can help extend the duration of the hydraulic cylinder. Avoid solid grease, as dust particles “glues” easily onto the piston rod and will damage the rubber. Also don’t forget to unlock the vent in the wintertime if leaving the vent openers set up. A good weak winter sun can high temperature the hydraulic cylinder sufficiently to create 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 strength. The solar vent opener may be the only solar-driven control with a quick-release mounting bracket. Simply grasp the “clutch” arm and squeeze for easy detachment. This enables vent to be fully opened for usage of the interior.
