FAQ's

Will this work on a flat roof home, or a garage with not attic space above? No, the SWGF-14 (garage/workshop without attic access) instead.

Garage door or wall intake vents – which do I need? That’s a personal preference on whether you’d prefer your cool, fresh outside air to enter through the garage door or exterior wall of the garage. Both are HOA compliant.

How loud is it while running?  55 decibels. About the same as a builder’s grade bathroom exhaust fan, or the equivalent of the road noise you here in your car with your windows up traveling at 65 MPH.
