Just The Right Accessory For You!
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
60°F to 75°F and an 18" maximum opening which would be reached
at approximately 90°F.
