Circular odour-proof check valves KPK

KPK circular odour-proof magnetic dampers are used to prevent air backflow through the air duct. KPK single-leaf self-closing dampers have a body made of ABS plastic, the diaphragm is made of silicone and there is a U-shaped seal around the perimeter of the damper to ensure the damper is tight in the duct. Long-term temperature resistance is +80 °C and short-term resistance is up to 85 °C. KPK leak-tight check valves are designed for direct insertion into ventilation ducts with diameters of 80 mm, 100 mm, 125 mm, 150 mm, 160 mm and 200 mm, for KG (orange) ducts 110 mm, 125 mm, 160 mm.
