Our Price: $44.95
Vent openers do not require electricity. The opener has a metal cylinder containing a mineral which expands when heated. This pushes a piston that opens the vent. As the temperature cools, the mineral shrinks and a spring closes the vent and resets the piston. The opening and closing of the vent is gradual allowing just the right amount of air flow for cooling.This control allows solar-powered control of top or side mounted window vents. These window openers have an adjustable opening temperature of 60F to 75F and an 18" maximum opening which would be reached at approximately 90F.Lifting capacity is 15 lbs.
