In order to prevent insects, sand or dust from passing through one of the seven exhaust canals, the automatic outlet fans are fitted with shutters. These shutters will only open when in operation thus preventing dust, sand or insects from entering the unit.

Located at places with temperature sensitive equipment, such as the batteries, the fridge and the freezer, the outlet fans are automatically activated when the temperature gets too high. The smart domotics system controls this operation. In the bathroom and lavatory outlet fans are installed with manual switches to avoid moisture and odours.
