Automatic Greenhouse Window Opener Replacement Cylinder

This automatic window opener replacement cylinder is designed to replace the inner mechanism of our greenhouse window vent. It provides reliable temperature control by using heat expansion to push the piston and open the vent, then contracting again as the greenhouse cools to close the window. This replacement cylinder is supplied with a 2 year warranty and fits only our automatic greenhouse window vent.

Automatic Greenhouse Window Opener Replacement Cylinder Sizes

The black cylinder measures 20cm in length. When the piston is fully contracted the total length is 28.5cm, and when fully extended the length is 33cm. The piston has a 2mm diameter hole, a thread length of 25mm and a piston rod diameter of around 5mm. These exact sizes ensure the replacement fits correctly into our greenhouse vent system.

How The Automatic Greenhouse Window Opener Replacement Cylinder Works

The cylinder operates with a special heat reactive substance inside the piston chamber. As the temperature inside the greenhouse rises, the substance expands and pushes the piston rod forward, opening the vent to release heat. When the temperature drops, the substance contracts and the piston retracts, allowing the vent to close. This process happens gradually without electricity, keeping the greenhouse at a steady environment.
