We have made these a standard item on our production line

Comments about Galvanized Steel Silencer for 6" Duct:

We have used these for years and have had great success damping the sound of up to 7.5HP blowers. The great thing about getting these from Supply House it the price and speed of shipping. I can get these quick elsewhere, but the cost is much higher. I can get these close to this price within 3 weeks other places, but Supply House is the Lowest price and I have them within 3 days. This has eliminated the need to stock these in our warehouse for the production of our Biomass Boiler systems. This set I bought is going to be floated 100+ miles down the Yukon River to heat a out lying river community in AK, and save them millions by burning local renewable wood chips, instead of diesel to heat their building in the AK winter.

Works well

Comments about Galvanized Steel Silencer for 6" Duct:

Installed on a commercial garage vehicle exhaust extraction system. Lowered the levels on my noise meter from 71db to 65db but perhaps even more in certain tonal ranges where the sound was especially annoying. Neighbors much happier. No report on longevity so only 4 stars.

Cuts fan noise by more than half

By Rick the fan man

from Davenport Fl.

Verified Buyer

Comments about Galvanized Steel Silencer for 6" Duct:

I mounted my Fantech exhaust fan about 15 feet downstream from my range hood. Airflow was great, noise was less than the original hood maounted fan, but the wife still made a face when I switched on the fan. Installing this silencer brought a big smile to her face, and ensured the fan would now be used while she creates another coronary delight.
