How to Maka a Quiet Exhaust System?

[Linda Tetreault]

We built a small shelter on the outside of the building, ran the duct work straight from the back of the laser to the dust collector, used about 6 ft of tubing, the cord from the blower comes in the same space so we can turn it on/off without going outside. It has worked great for us for 5 years & most of the noise stays outside.

I finished my exhaust system and used a 6" metal duct vs the 4". I also place my blower right next to my machine and the duct runs less than 8 feet to my vent. I wrapped the metal duct with a packing blanket and some carpet to reduce the amount of noise the air makes when it is vented out.
The blower I used was a Craftsman 3/4 HP rated at 650 CFM's. It seems like it is pretty strong and blows a lot of air - it is also super quiet which is the reason I bought it. My noise level with the machine, air compressor, and blower is very quiet - much less noise than my Rigid Shopvac
Thanks again for all the help
