Palram Auto Vent Opener
The Palram Auto Vent Opener was designed to automatically control the temperature and humidity levels and provide additional ventilation when needed, making gardening easier. The Palram Auto Vent Opener is easy to install and no electricity is required. There is a liquid in the cylinder that expands as the temperature nears 70 degrees causing the vent to gradually open to allow the correct amount of air flow into the greenhouse and close when the temperature cools.
The vent arm was designed with a metal cylinder containing wax which expands when heated 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 and resetting the piston. All you need to do is to install it on your roof vent window and it automatically starts working. The Automatic Vent Opener operates without the use of electricity and is compatible with all Palram greenhouse models only.
