Ventilation window vent PO 400

The window ventilator PO 400 is the air intake mechanism designed for permanent ventilation and continuous air supply to residential and public premises. This ventilator is suitable for installation into various sized window frames in flats, cottages and office premises. Proper air exchange is a fundamental prerequisite of occupant comfort in modern residential buildings. Unlike the old days when ventilation system designs were based on the assumption of outdoor air supply through numerous cracks in the window frames, today most windows are built to be air-tight forcing to seek other solutions. A window ventilator is a passive device which ensures natural flow of fresh air through the otherwise airtight window frames. Window ventilator PO 400 is a continuous supply unit designed to deliver fresh air into residential and non-residential spaces. Such ventilators can be integrated into frames of various sizes in flats, detached houses and office buildings. A supply air unit eliminates the need of opening windows ensuring a consistent flow of fresh air without creating drafts and letting in street noise. Due to a purpose design the ventilator is very user-friendly while the integral dust filter keeps the indoor air free from impurities. The following example illustrates ventilation of a flat in a multi-storey residential block. Mechanical exhaust ventilation systems with natural fresh air flow are designed to rely on exhaust fans installed in the kitchen and the bathroom. The fresh air is supplied to the habitable inner spaces (i.e. bedroom and living room) through the window frame ventilators.
