MACO VENT ventilator

MACO window ventilation system

Revitalise your quality of life

Manual airing of a room is often not enough and leads to bad air, condensation or mould. The solution for this is the MACO Vent concealed window rebate valve. It ensures a minimum airing if there is no-one at home and thereby prevents any condensation problems. This intelligent component sits recessed in the window rebate and reacts automatically to wind, but can also be closed manually if needed. This window ventilation system also regulates the fresh air supply and prevents strong drafts. MACO Vent is thus an investment in well-being and at the same time protects the building itself.
