Automatic Vent Opener for Greenhouse
The Automatic Vent Opener was designed to automatically control the temperature and humidity levels. It provides additional ventilation for all Palram – Canopia Greenhouses, making gardening easier. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of airflow into the greenhouse until the optimal temperature is reached. The vent arm was designed with the use of wax that expands with heat and contracts when it cools. The Automatic Vent Opener operates without the use of electricity.
- Opens roof vent automatically as temperature warms for air circulation and heat relief,
closes when temperature cools. - Solar powered, heat activated – start opening point: 12°-15° C
- Mechanic system – no electricity is needed.
- Suitable for all Palram – Canopia greenhouses with roof vents.
- Easy to install.

Works great, just don't lose the locking pin....
The Automatic Vent opener works great. Lost one of the locking pins while installing, and was hoping to get some replacement "locking pins". After multiple e-mails and a reminder to give them the part number, I have been told that the locking pins are not available separately unless we get the complete Automatic Vent Opener...Functions very well , good product for its money
Really interesting gadget.Great vent
It operates efficiently without requiring power.
