Take control of the air that comes into your house. By installing a supply air vent in the right place, you can, for example, get rid of unwanted floor drains. Always place the vent high up on the wall. If you have radiators under the windows, mount the vent above the windows. If you have underfloor heating, the vent should be placed about one meter away from the window.
We have both manually and thermostat controlled wall vents for Ø80 och Ø100mm.
