Automatic Greenhouse Window Opener The Automatic Vent Opener was designed to automatically control the temperature and provide additional ventilation for all our Greenhouses. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of air flow into the greenhouse and closes when the optimal temperature is reached. The vent arm was designed with the use of wax that expands with heat to push a piston, which raises the window, as the air gets warmer then contracts as it cools, closing with the use of a spring. The Automatic Vent Opener operates solar energy – it’s FREE to run!Warm tips: -Do not use this opener anywhere the temperature will exceed 60° (140f) -Please ensure your greenhouse window can be opened freely by at least 45cm (18″) -Get the very best from your greenhouse plants and veggies – don’t leave it to chance!Package included: 1 x Automatic window opener 1 x Step-by-step assembly instructions
