The Mercator Cosmo Duo 2 exhaust fan is usually hardwired by an electrician to a switch. The installer can wire it so the fan and light work separately, from separate switches, or together from a single switch. This Cosmo Duo model has a very high capacity of 500m3/hr.
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 out the recommended capacity needed for your room, 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 install in a bathroom who have a lot of glass and prefer to have warmer showers should get a fan double or more the recommended capacity.)
Note: If you install an exhaust fan with ducting, there will be a loss in capacity resulting in fewer air changes per hour.
