The function of a Louvers/curtain Fire Damper is to close automatically upon detection of heat, in order to protect the integrity of a fire CAD Forum – Block External Curtain type Fire Damper. And the Louvers/curtain type fire damper roll forming machine could be used to make the curtain type fire damper in batch by roll forming principle. From the decoiler to roll forming and then shearing, all are full automatic, no need person to interface the work. The working speed could reach 20m/min.
The fire damper roll forming machine working process:
Decoiler leveling system roll forming machine shearing system runout table
