The Boris exhaust fans can be fitted into standard glass windows and wall panels, and are suitable for a range of domestic and commercial applications including toilets, bathrooms, washrooms, kitchens, offices and storerooms.

This fan wil normally run as an exhaust fan, extracting air from the room but it can also run in reverse, bringing air in from the outside.

These exhaust fans feature fast operating shutters at the back that eliminate backdraft by providing a barrier to the outside elements. The the shutters are operated when the fan runs and springs ensure minimal wind noise when the fan is not operating.

The fans are easily installed by one person from inside the building, eliminating the need for a second person and making multi-storey installations safer and more convenient.

Note this fan is best suited for installation on wall panels (thin) and glass windows.

A rubber seal is provided to go around the rim of the hole in the glass (or panel)
