Grandio Auto-Louver Window Opener - Left Side Orientation for models purchased after September 2016
Automatically opens and closes the louver window when temperature changes. The opener has a metal cylinder containing a mineral which expands when heated. This pushes a piston that opens the window. 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.
