The Lenco window exhaust Fan is specifically manufactured for long life operation and can be installed quickly and economically in windows with a minimum glass thickness of 4mm. The grille is easy to remove for cleaning and the external cowl prevents wind and rain from entering.
It is recommended to achieve a minimum of 10 air changes per hour in a bathroom, toilet or laundry, to remove excess moisture.
To work this out, calculate the volume of air in the room ( length x width x height, all in meters) and multiply this by the number of air changes to get the required air volume of the fan. (This will be adequate in most normal situations. We recommend that those clients who have a lot of glass and prefer to have warmer showers should get a fan double or more the recommended capacity)
