Underfloor Swirl Diffuser (Polymeric Construction, Fire Rated)
Krueger’s FPDFR-R curved slot, fire rated, helical air pattern diffusers are designed for interior spaces where the environment requires a greater degree of flexibility to easily adapt to changing floor layouts in underfloor installations. The FPDFR-R comes with an integral dirt receptacle that catches debris from passing traffic and is easily removable for cleaning. The integral dirt receptacle also functions as a volume damper, which may be adjusted by rotating the face of the FPDFR-R giving the occupant greater (perceived) temperature control.
