This Halls Autovent is a really useful, time saving device that attaches to any vents in your Halls greenhouse.

This is an automatic vent system that attaches to the window that is to open, providing vital ventilation to your plants. The sun heats up the auto vent cylinder, causing it to expand, and open your window, and should the temperature go down then this handy device will automatically close the window, making sure your prize plants get the perfect temperature all the time.

  • Easy fitting.
  • Automatically opens and closes greenhouse window.
  • Ideal for hot spells and holidays.

The beauty of this device is that once you have fitted it then you don’t have to remember about opening the windows in your greenhouse – it is done for you.

Operating temperature: Between 15 and 25 degrees Celsius

Weight capacity: Will lift a window weighing 7kg
