VENTAIR II TRDn and VENTAIR II differential pressure-controlled ventilators are used to supply a constant, proper amount of fresh air to rooms. Automatic pressure control stabilizes the efficiency of the supply, protects against excessive air exchange during cold and windy periods, allows the implementation of the concept of controlled ventilation providing comfort and healthy indoor climate while saving thermal energy. They are used in rooms equipped with gravitational or mechanical exhaust ventilation.
