Steel Plenum Slot Diffuser (Dual Curved Blade, Adjustable)
The PTBA series plenum slot diffuser features “ice tong” blades that allow for adjustment from horizontal flow to vertical flow. The “ice tong” blades allow the occupant to easily adjust the airflow pattern depending on airflow requirements. 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 PTBA series diffuser an ideal choice for perimeter heating and VAV cooling applications.
