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.

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.

"The bracket on the vent arm was different to the one depicted in your advice email. I needed to remove the existing bracket on the window to attach the vent bracket."
