PLQLT - Steel Diffuser

The Krueger PLQLT is a 24”x24” steel diffuser designed for architectural integration and optimal performance in low temperature HVAC applications. Featuring a unique one-piece, non-folded square faceplate, the PLQLT ensures a streamlined aesthetic without compromising airflow. The faceplate is backed by a 3/8” thick cellular liner, providing insulation from cold supply air and contributing to the diffuser’s quiet operation and reduced pressure drop. Easily removable, the faceplate allows for convenient access to ductwork and damper systems during maintenance.

Engineered for durability and lasting performance, the PLQLT diffuser boasts a one-piece, stamped backpan that guarantees smooth corners, precise dimensions, and reliable performance tolerances. To prevent condensation and enhance energy efficiency, the backpan is covered with a foil-faced R-6 formed fiberglass backing. Available in a variety of frame styles to complement any architectural design, the PLQLT integrates seamlessly into any space.

The PLQLT diffuser is available with round inlet sizes ranging from 6” to 15” to accommodate a range of airflow requirements (for the 24”x24” panel size). Its steel construction ensures long-term durability while the standard British White finish provides a clean, professional appearance. The Krueger PLQLT is categorized under Masterformat Division: 23 37 13 Diffusers, Registers and Grilles, meeting industry standards for HVAC projects.
