The KDK 20WUD is an 8-inch glass-mounted ventilating fan with an auto-close outdoor shutter, delivering 212 CFM, for bathrooms and kitchens with a glass window or thin panel opening.
How is this installed?
The fan itself clips and screws into a pre-cut circular opening (usually cut by a glazier if your glass doesn't already have one) — fitting the fan into an existing hole is a straightforward job. The outdoor shutter closes automatically when the fan is off, keeping out insects, dust, and humid air.
