Wall exhaust fans eliminate humid air, fumes and odors, primarily in commercial facilities. These fans work wonders to remove humid air from laundry areas, tobacco-filled recreational rooms, fumes from car body shops or garages, and odors and heat from the kitchen. Shop online or at your local hardware or home improvement store to compare brands, styles, features and prices.
Place the fan’s housing on the wall and trace around the inner part of the fan housing with a marker or make a template using a piece of cardboard and the fan housing. Drill a starter hole in each corner of the outline you made on the wall. Place the coarse saw into one of the starter holes and cut from hole to hole until the cutting is complete for the interior wall.
Drill a starter hole in each corner of the exterior wall template. Place the saw in one of the corner holes and cut from hole to hole to make the opening for the damper door housing. Place the fan in the hole and attach the damper door housing using the fasteners provided. Turn the power off at the main circuit breaker or fuse box located in the basement or utility room. Test the hot wire (black) with a voltage tester to make sure there is no electrical current.
