Steel Plenum Slot Diffuser (Fixed Blade, Downblow)
The PTBSCDB series plenum slot diffuser features a curved blade that directs a horizontal discharge air pattern and a center down blow section that discharges air vertically. The PTBSCDB blades are shipped attached to the unit and are non-removable. The center down blow blades are “ice tong” blades that can be adjusted for vertical angled throw and vertical down blow dampening. The plenum is an integral part of the diffuser and has a drawn inlet collar to prevent plenum air leakage.
