The Skylight/Window Exhaust Fan provides an effective alternative where a skylight has been fitted and other fans cannot easily be used.
With ball bearings for or long life, it can be installed quickly and economically in glass and acrylic skylights.

The Skylight exhaust fan is designed for kitchens, laundries and bathrooms, in which skylights have been fitted. While the fan helps circulate fresh air, it also enables keeping the walls and dome of the skylight in clean condition. The Skylight exhaust fan is installable in acrylic as well as glass skylights. The window model is very similar with just the "cowl" at the back being slightly less deep.
