KD-TC Non Return Damper

ASLI Non Return Damper (KD-TC) is designed for automatic shut off of individual section of air conditioning system. Contemporary styling features blades that overlap the frame for optimum leakage proof. The counterbalance arm provides the flexibility to increase or reduce the pressure drop across the damper; hence KD-TC can serve as a pressure relief damper as well. The damper’s aesthetical appearance is maintained by sturdy, corrosion resistant aluminum and galvanized steel construction. Two models available, KD-TC1 and KD-TC2 for heavy duty usage.

Spring-loaded or gravity-operated blades close automatically when airflow stops.
