Description
Square round fire damper is made by equipping two circular transition flange on both ends of rectangle damper channel. The damper body is square, of which the side length is equal to the diameter of circle damper. The thickness is ≤340mm. Square round fire damper possesses the advantage of rectangle damper, the rigidity and strength of blade is superior than the circular damper, good tightness and less leakage. Our suggestion is to use Square round fire damper in the pipe with diameter >Φ500mm. At ordinary times, it is normal open, in fire situation, closed to prevent fire and smoke.
