Greenhouse Vent Opener

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 surroundings inside the greenhouse warms, the vent gradually opens to enable the right amount of air flow in to the greenhouse and closes when the temperature cools. The vent arm was designed with a metal cylinder that contains wax which expands when heated to press a piston, which raises the screen, as the air flow gets warmer, then agreements as it cools, closing with the use of a spring and resetting the piston. All you have to to do is usually to install it on your roof vent windows and it immediately starts operating. The Automatic Vent Opener functions without the utilization of electricity and works with with all Palram greenhouse versions only. The solar driven Vent Opener will begin to open as temperatures 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 Greenhouse Vent Opener device that automatically opens and closes coldframe lids, greenhouse windows and actually skylights. Works throughout the day and maintain a continuous 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 every our glazed season extenders since it dramatically increases plant growth.
The hydraulic cylinder has 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, wooden, or metal frames. The Standard Vent Opener can open up a hinged screen or vent weighing as much as 32 lb. For larger panes use the more powerful Gigavent with all metal structure, to lift up to 65 lbs.

Note from the manufacturer: Suggested to lubricate the piston rod yearly, this can help extend the lifetime of the hydraulic cylinder. Avoid solid grease, as dirt 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 leaving the vent openers installed. Even a weak winter sun can 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 is the only solar-operate control with a quick-release mounting bracket. Simply grasp the “clutch” arm and squeeze for easy detachment. This allows vent to be fully opened for usage of the interior.
