5050

Application

Series 5050 is a combination fire & smoke damper with a 1 1/2 Hour UL555 firerating available with your choice of Class I, II, or III UL555S Leakage rating. Thisdamper utilizes a thermally responsive electric switch to allow for the return springof the specified actuator to close the damper upon elevated temperature. Thedamper may be installed vertically or horizontally for use in barriers requiring bothfire and leakage protection. This damper has been evaluated with bi-directional air-flow, and is rated to 2000 FPM and 4" static pressure in compliance with UL555 6thedition and UL555S 4th edition.
