Circular duct silencers are designed and manufactured for installation in ducts and fans with circular cross-sections. These devices are specially engineered to reduce noise levels in specific octave bands within HVAC systems. Circular silencers are available in two models: without internal baffles (non-baffled) and with sound-absorbing baffles (baffled). Our company manufactures a wide range of duct silencers in various sizes and dimensions.
