The check valve can be used universally in all standard round ventilation pipes and flexible hoses according to DIN EN 1506. Stainless steel is weather and corrosion resistant. The aeration grille 100 is mounted on the outer wall of the air discharge system. When the fan stops, the slats automatically close and prevent the ingress of cold air and the ingress of dirt, insects and other objects. Due to the ease of movement, the flaps open at very low pressures, which is why they are also called floating flaps. Suitable for extractor hoods, workshops, basements, tumble dryers and much more.
