Comfort and convenience The exchange of too dry or too humid air eliminates all the impurities and odours which may enter from the outside e.g. through an opened window. The work of the air handling unit allows to adjust the temperature and humidity level in the room through ensuring the constant inflow of fresh and clean air. Owing to the controller attached to the appliance, a user has a full control over the amount of the air exchanged, and a particularly user-friendly interface makes working with our air handling unit more than pleasant. Moreover, when we do not like uninvited guests such as insects or when a noise coming from the outside becomes a nuisance, we can now sleep tight. When our windows are closed, nothing and nobody disturbs us and the air handling unit will work constantly to provide us with fresh and clean air.
