Circular odour-proof check valves KPK2

KPK2 circular odour-proof magnetic dampers are used to prevent air backflow through the air duct. KPK2 double leaf self-closing dampers have a body made of ABS plastic, the diaphragm is made of silicone. Long-term temperature resistance is +80 °C, short-term up to 85 °C. KPK2 butterfly valves are designed for direct insertion into ventilation ducts with a diameter of 80 mm, 100 mm, 125 mm, 150 mm, 160 mm and 200 mm, for KG (orange duct) 110 mm, 125 mm and 160 mm. Thanks to two magnets and a pair of wings with a stronger construction and better adhesion, better sealing of the check damper is ensured.
