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.
- Rectangular sound attenuator
- Cleanable design
- Excellent attenuation qualities
- Efficient and aerodynamic internal dividers designed to achieve very low pressure drop
- Cleanable Therwoolin surface layer on the insulation
The casing is made of galvanized sheet steel. The sector panels are made of high quality absorption material, with laminated cleanable surfaces type Therwoolin.
