Circular cross-section sound attenuator with 50mm insulator
Circular, straight sound attenuator with 100 mm mineral wool insulator. The outer cover of the duct is made of corroded, welded material and the inner cover is made of perforated material, so it can effectively withstand mechanical cleaning while maintaining sound attenuation.
