The RBR sound attenuator was designed to fit rectangular duct connections, and to reduce sound levels in duct systems. The attenuator was developed in a cleanable design, with removable internal baffles. The RBR attenuator is sector panel designed, and comes in a wide range of configurations and materials, and is available for either exterior or interior applications.
