The SHRPLQ series square diffuser provides the building designer with the desired plaque diffuser appearance and superior throw performance. The 24”x24” SHRPLQ has one, two, or three slots with a square plaque face in the center. The removable core offers easy duct and damper access. They feature a 1/4” horizontal lip on the louvered core, resulting in a tight horizontal pattern at the ceiling and a higher discharge velocity at the face. This creates a high induction region just below the face of the diffuser, which makes them an excellent choice for variable air volume systems.
