Steel Plenum Slot Diffuser (Flat Blade, Adjustable)
The PTBS series plenum slot diffuser features a unique, gasketed aluminum blade that rotates for easy adjustment from horizontal flow to vertical flow. The PTBS blades can be locked into a discharge position by tightening the blade screws at each end of the diffuser to provide consistent performance after system balance. 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 fully adjustable discharge air pattern from horizontal to vertical and any point in between makes Krueger’s PTBS series diffuser an ideal choice for perimeter heating and VAV cooling applications.
