Model Series DW Wall Mounted Displacement Diffusers maximize floor space by seamlessly integrating into the wall, supplying conditioned air to the space perpendicular to the diffuser face. The design features a flat perforated face that creates a low velocity air pattern. The series includes an internal wall mounted type that has a removable face, a flangeless style that can be easily recessed in a low-wall or stair riser and a flanged grille type that easily mounts to a sidewall.
