Sidewall Displacement Diffuser
The Sidewall Displacement Diffuser (SDD) is a unique diffuser that supplies low velocity discharge air in a 1-way pattern into an occupied zone from relatively hidden locations. The SDD has an easy to install perforated face that is securely retained with mounting clips in a contractor supplied plenum. A mud frame is available for drywall applications. With no visible fasteners the SDD can be discreetly installed in stair risers, in a wall at floor level or in a toe kick, making it ideal for classrooms, theaters and lobbies.
