Greenhouse Window Auto Vent Opener

Be sure to keep your greenhouse at the right temperature even when you are not around.

Try the Greenhouse Window Auto Vent Opener. Rest assured that your greenhouse will get ventilated properly when you are away. It makes greenhouse keeping so much easier!

DURABILITY & FUNCTIONALITY - The cylinder and vent opener apparatus are constructed from sturdy aluminum alloy. The vent opener mechanism operates smoothly and easily to open or close windows in response to temperature changes. It is engineered to open windows by up to 45 cm. Please ensure that the windows are not forcibly shut by a lock or cover.

SOLAR-POWERED OPERATION - No electricity is required. After assembly and placement, the window opener will operate hands-free. When heat increases in the greenhouse environment, the cylinder responds and expands, causing the vent opener apparatus to spring upward, pushing the window open. This will ensure that your greenhouse receives proper ventilation automatically, keeping it from overheating.

EASY TO ASSEMBLE - The mechanism can be put together with ease. You need to screw two small plates onto the vent opener apparatus. Each one has to be screwed onto the large contact plates on the upper and lower arms of the opener. Then the cylinder has to be screwed into the valve opening and secured in place by inserting the cotter pin into the central valve. Then you can attach the opener to the window by pinching the window frame using the contact plates. Tighten the screws to keep the plates from slipping. The process only takes a few minutes to complete.
