2" Duct Silencer for HS Series Radon Fan

Duct silencers or duct mufflers are used to attenuate airborne noise through radon mitigation systems. The radon system silencers will attenuate noise levels by almost 10 dBA.

Please note that every 3 dBA in noise level reduction cuts your perception of noise by half.

Our radon reduction system mufflers will not affect airflow through your mitigation system because the open bore of the silencer has the same diameter as the duct in witch is installed.
