Lacewing™ Essential Automatic Vent Arm Window Opener / Autovent

The autovent window opener is an all-in-one solution for greenhouse temperature control. Using a cleverly designed pressure system, the arm opens the window if the greenhouse is over a preset temperature, and closes the window below this temperature. Care for your greenhouse plants, even when you're not at home.

Features
  • Automatically opens and closes window at preset temperature - increases air flow and relieves your plants in hot temperatures
  • Fully adjustable to open between 15°-20°C - set the temperature the window will open and close at to care for your specific plants and climate
  • Opens up to 35cm wide - opens wide to encourage air circulation
  • Mechanical system activated by heat - no electricity needed, which means no running costs
  • Perfect for windows that weigh up to 7kg - opens nearly all greenhouse windows
  • Chrome coated metal - increased corrosion resistance
All greenhouses need to be well ventilated on hot and sunny days to keep plants in optimum growing conditions. The automatic vent arm uses captured gas which expands in hot temperatures, opening the window without any running costs. The simple but smart mechanism will maintain optimal temperatures at all times, whether you are or aren't at home. You can adjust the opening temperature between 15° and 20°C to suit your individual needs. Simply install the vent opener by using the instructions and let it do its job.

"Good design but in the lacewings green house, it needs a small packing piece on the fixed arm to give enough clearance for the moving arm to close completely. I made one out of an old white plastic chopping board.
The other thing is, if this is made for lacewings greenhouses, why don't the screw holes on the swing arm match the predrilled holes in the green house window frame?

"Although this should be a direct replacement for the manual vent I found that the bracket holes did not align with thos in the greenhouse so had to make a small modification to get it to fit (spacing across the two holes was different. Otherwise seems of good quality but with recent weather not had chance to see if it works by itself yet."

"Service excellent. Unfortunately delivery came in two drops, but the driver was a pleasure to deal with. Greenhouse took two men about six hours to put up and it was in use immediately. Very good value"
