Air Vent 53830 Roof Mounted Power Attic Ventilator

Electric-powered attic vents use a thermostat and humidistat control to monitor heat and moisture buildup inside the attic. Featuring a low-profile dome, the power attic vent is unobtrusive when installed on the roof slanting away from the front of home. It's an efficient option to replace wind turbines or roof pots already in place.
