NKTM

The NKTM pressure relief non-return dampers are used for automatic closing of HVAC ducts in case of fan shutdown. The NKTM pressure relief non-return dampers are designed either without rod (design .01) or with rod (design .01T). The NKTM non-return dampers prevent backflow of air in case of shutdown of a fan. The maximum flow speed is 12 m / s and the maximum overpressure in the damper is 1500 Pa.

The NKTM non-return dampers are designed for installation in HVAC ducting or for installation at its end. The pressure relief damper is designed for installation in vertical or horizontal ducts. If installed in horizontal ducts, the axis of damper blades must be horizontal. Damper bodies and blades are made of galvanized sheet metal without further surface treatment. Plain bearings are made of durable flame retardant nylon.
