PTBSSFB
Steel Plenum Slot Diffuser (Factory Mounted Fixed Blade)
The PTBSS (or fire rated, PFTBS) series plenum slot diffuser features a curved blade that directs a horizontal discharge air pattern. The PTBSS blades are shipped loose for field installation or the factory can mount the blades (PTBSSFB). The plenum is an integral part of the diffuser and has a drawn inlet collar to prevent plenum air leakage and simplify installation of the diffuser. The fixed horizontal discharge air pattern makes Krueger’s PTBSS series diffuser an ideal choice for tenant areas that have short tenant life cycles and VAV cooling applications.
