FD-111-PB PARALLEL BLADE DYNAMIC FIRE DAMPER
The FD-111-PB Parallel Blade Dynamic Fire Damper is a multi-blade dynamic fire damper approved for use in walls, floors and partitions with fire resistance ratings less than 2 hours. The FD-111-PB Dynamic Fire Damper carries a 1-1/2 hour UL fire damper label. UL 555 classifies dynamic rated fire dampers for use in HVAC systems. This is the style of fire damper that is used in the manufacture of FSD (Fire and smoke dampers) and Smoke dampers. It is available with or without sleeves, with round or oval connectors, and in stainless steel. Fairly rarely specified, it used less often than curtain style fire dampers because it costs more.FD-111-PB Dynamic Fire Damper Technical Specifications
