Automatic window opener
Avoid diseases and pests in your plants by airing out. Many plants do not tolerate high temperatures and high humidity. Ventomax is an automatic window opener in black galvanised-steel.
Best suited for glass. Can be set to open and close between 16°C and 25°C. The heat causes the oil in the cylinder to expand, so the window opener automatically opens the window. Read more about window openers and choosing the right window opener for your greenhouse.
