Review Fantech LD 10 Silencer 10" Duct

Fantech LD 10 Silencer for 10 inch Round Duct Tested out good so far. Review by Atto on 5/2/12. I haven't installed the silencer yet, but I did test it vs. a section of regular 10" duct, using my wife's hair

Galvanized Steel Silencer for use in Kitchen Range Hood Ventilation and Other Applications Were Noise is a Concern. A Fantech Silencer Can Typically Reduce the " Perceived" Sound Level of the System by More than 50%. Units Feature Rubber Seal On Inlet and Outlet. Feature and Specification Sound Data: 6 Suppression dB for 125 Hz
