Curtain Fire Dampers
Nailor manufactures a variety of curtain type fire dampers to suit a wide array of applications that may require protection of openings with fire resistance ratings of either 1 ½ or 3 hours. Dampers are UL 555 rated for static and dynamic systems, with extended airflow velocity and pressure ratings available.
Nailor D0100 and D0500 Series Dynamic Curtain Fire Dampers are UL 555 tested and approved. Classified for use in dynamic "fans on" systems where the HVAC system remains operative in the event of a fire. Damper closure under airflow is assured.
Nailor 0100, 0200, 0300, and 0500 Series Static Curtain Fire Dampers, for use in static "fans off" systems where the HVAC system shuts down in the event of a fire, are UL approved to provide 1 ½ or 3 hour protection of HVAC ductwork penetrations in walls, partitions or floors.
