Automatic Roof Window Opener for Grandio Essence Wind MPH 56 ml/hrDESCRIPTION Automatically opens and closes the roof vent window when temperature changes. 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. SKU: AUTO ROOF SPEC Weight: 1. 0 LB
