PTBSCDB - Steel Plenum Slot Diffuser (Fixed Blade, Downblow)

The Krueger PTBSCDB is a steel plenum slot diffuser designed for lay-in T-bar ceiling systems. This combination diffuser features a fixed blade design with a curved blade that delivers a horizontal discharge air pattern, ideal for achieving optimal air distribution in HVAC projects. A unique feature of the PTBSCDB is its center down blow section, which utilizes adjustable “ice tong” blades to provide a focused vertical air stream. This combination of horizontal and vertical air discharge makes it highly effective for a variety of spaces within the construction industry.

Engineered for efficiency and performance, the PTBSCDB series comes with a plenum that is an integral part of the diffuser unit. This integrated design, coupled with a drawn inlet collar, effectively eliminates plenum air leakage. The diffuser is available in a range of sizes, with supply slots in 24”, 36”, 48”, and 60” lengths to accommodate diverse project needs. Customization options include factory-installed T-bars, external insulation, and a quadrant damper.

The Krueger PTBSCDB diffuser arrives with a standard black finish on the face and deflectors. Its robust steel construction ensures durability and long-lasting performance, making it a suitable choice for demanding commercial and industrial applications. Classified under Masterformat Division 23 37 13 for Diffusers, Registers, and Grilles, the PTBSCDB is a reliable solution for achieving balanced and effective air diffusion in any commercial HVAC system.
