This non-electric roof vent opener is simple to install and is completely automated. A threaded adjuster bolt can set the Bayliss to start opening the vent at approximately 55 degrees Fahrenheit. This vent opener uses a very simple principal - Special waxes have an expansion rate of about 18% when heated by the sun. As the air in the greenhouse heats up it also heats the powertube in the vent opener. As the wax expands it pushes out a stainless steel piston that slowly opens the vent up to 12 inches. The hotter the temperature the wider the opening. When the temperature cools the weight of the vent and a 6 1/2 pound stainless steel spring closes the vent and holds it closed.
Key Features:
- Fully automated and non-electric vent opener
- Adjustable opening point, typically around 55°F
- Uses solar-activated wax that expands to open the vent up to 12 inches
- Stainless steel piston and spring ensure smooth opening and reliable closing
