About Bayliss Solar-Powered Vent Controls
These "top of the line" solar vent controls will open and close greenhouse vents automatically without electricity. Bayliss vent openers convert energy from the warmth of the sun into mechanical energy to open vents. The hotter it gets, the wider the vents are opened.
Bayliss solar vent openers are made from the best corrosion-resistant materials: brass, stainless steel, and satin anodized aluminum. They are designed to give many years of service, and can be repaired should the need arise.
