The Automatic Vent Opener was made to automatically control the temperature and humidity amounts and provide additional ventilation when needed, making gardening easier. As the atmosphere inside the greenhouse warms, the vent steadily opens to enable the correct amount of air flow 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 drive a piston, which raises the windows, 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 certainly to install it on your own roof vent home window and it immediately starts functioning. The Automatic Vent Opener functions without the usage of electricity and is compatible with all Palram greenhouse versions only. The solar powered Vent Opener will start to open as temps within your greenhouse reach 68 degrees F with full-open at 80 degrees. It installs efficiently and can provide care-free ventilation.
Ingenious temperature-delicate device that automatically opens and closes Greenhouse Vent Opener coldframe lids, greenhouse windows and even skylights. Works throughout the day and maintain a constant interior climate, something unattainable to accomplish by manual adjustments.
Requires simply no batteries or electricity.
It could be adjusted to begin 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 improves plant growth.
The hydraulic cylinder comes with a 1 year warranty. The common lifetime of the cylinder is certainly 5-10 years, although some can last up to twenty years.
Screw directly 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 bigger panes use the more powerful Gigavent with all metal building, to lift up to 65 lbs.
Note from the maker: Recommended to lubricate the piston rod annual, this can help extend the lifetime of the hydraulic cylinder. Avoid solid grease, as dirt particles “glues” quickly onto the piston rod and will harm the rubber. Also don’t forget to unlock the vent in the winter if leaving the vent openers installed. Even a weak winter sun can warmth the hydraulic cylinder sufficiently to create 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 may be the only solar-driven 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.
