Air intlet construction

	Automatic V40P Air Inlet Positioned in the top part of the frame. At a pressure difference of 10Pa air inlet capacity is up to 49m³/h depending upon the window width. The capacity rises up to the point where the optimum value is achieved. If the pressure difference continues to grow, the airflow capacity stays on the same stable level. The elastic, pneumatic flap deflects, limiting the amount of inflowing air by reducing the air inlet duct area.
	Air inlet V35 Positioned on the top part of the window frame. When fully opened this inlet supplies fresh air up to 41m³/h at a pressure difference of 10Pa depending upon the window width. As a result of this great efficiency, air humidity inside the room is effectively reduced, thereby reducing condensation. The V-35 air inlet can in part discharge air when normal gravitational ventilation isn’t working properly. Its excellent venting efficiency guarantees that a greater amount of stale and humid air is removed from the room.
	Air inlet V10 Positioned on the top part of the window frame, the V-10 has a manual adjustable air flow regulator. When fully opened this inlet supplies fresh air at 9m3/h at a pressure difference of 10Pa. The inlet’s construction provides excellent filtering and acoustic insulation. The air inlet V10 should be used solely in rooms where unassisted gravitational ventilation works well. Used in FTS-V windows
