Air Vent 1500 CFM Mill Finish Galvanized Steel Electric Powered Attic Fan with Built-in Humidistat

Electric-powered attic vents use a pre-wired Humidistat/Thermostat to monitor heat and moisture build-up 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 your home. Roof-Mount Power Fans are a type of motor-driven attic exhaust vent that make up half of a balanced attic ventilation system for each roof. Intake vents make up the other half of the system. Together they help remove any built-up heat and moisture inside the attic for year-round ventilation. Use the Home Depot calculator to determine how many Roof-Mount Power Fans are needed per roof.
