Lacewing™ Deluxe Automatic Vent Arm Window Opener / Autovent

The automatic vent opener is a popular choice for greenhouse venting systems. The vent arm automatically opens the window at warm temperatures for air circulation and heat relief, preventing build-ups of excessive heat. When the temperature cools down, it closes the window. This great item maintains optimal temperature even when you aren't at home, and doesn't cost anything to run.

Features

  • Automatically opens window at preset temperature and closes when temperature drops
  • Fully adjustable to open between 15°-23°C
  • Opens up to 35cm wide
  • Mechanical system activated by heat - no electricity needed, which means no running costs
  • Perfect for windows that weigh up to 7kg
  • Automatic response to weather changes - controls the temperature without requiring your attention
  • Chrome coated metal for increased corrosion resistance
  • Easy to install using instructions included
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 25°C to suit your individual needs. Simply install the vent opener by using the instructions and let it do its job.

"We have been unable to decifer the very poor instructions on how to fit it so it is still sitting on the side in the garage. Really feel these need to be much more explicit n larger and more step by step diagrams would be most useful."
