The air inlets are main elements of ventilating system assuring proper inflow of fresh air into rooms.

They are designed to use in rooms equipped with gravitational and mechanical ventilation.

Thanks to selfregulator of the air flow (reacting on difference of pressures), the quantity of blown air is solid, independently from atmospheric conditions (wind, cold).

Air inlets have a possibility of additionally hand regulation of the air flow, even to be closed.

They belong to the group of air inlets assembled in upper, horizontal constructional profiles of windows.

They consist of two elements – the air canal assembled outside and an internal regulator. These two elements are joined with the canal in the profile.
