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 atmosphere inside the greenhouse warms, the vent steadily opens to allow the correct amount of ventilation in to the greenhouse and closes when the temperature cools. The vent arm was designed with a steel cylinder that contains wax which expands when heated to force a piston, which raises the window, as the surroundings gets warmer, then agreements since it cools, closing with the use of a spring and resetting the piston. All you need to do is definitely to install it on your roof vent windowpane and it automatically starts operating. The Automatic Vent Opener functions without the usage of electricity and works with with all Palram greenhouse versions only. The solar driven 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-sensitive device that automatically opens and closes coldframe lids, greenhouse windows and actually skylights. Works during the day and maintain a continuous interior Greenhouse Vent Opener climate, something unattainable 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 almost all our glazed season extenders because 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 twenty years.

Screw straight into polycarbonate panels, wood, or metal frames. THE TYPICAL Vent Opener can open a hinged home window 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 annual, this will help extend the lifetime of the hydraulic cylinder. Avoid solid grease, as dust particles “glues” very easily onto the piston rod and can harm the rubber. Also don’t forget to unlock the vent in the winter if departing the vent openers set up. A good weak winter sun can heat 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 strength. The solar vent opener is the only solar-powered control with a quick-release mounting bracket. Simply grasp the “clutch” arm and squeeze for easy detachment. This enables vent to be completely opened for access to the interior.
