Juliana Univent Automatic Greenhouse Window Opener

The "Univent" automatic window opener opens by itself in automatic mode, ensuring your greenhouse always receives adequate ventilation. The robust aluminium system features two springs and attaches to the greenhouse window. At temperatures between 16 ºC and 25 ºC, the oil inside the cylinder expands, causing the window to open automatically. An ideal solution for preventing excessively high temperatures and humidity levels.
