Recommendations for noise reduction include using PVC instead of metal for ducting, having a few short sections of flex hose to isolate the cyclone, and adding a muffler to the exhaust. One installation suggests these steps help lower noise from 92 dB to 73 dB, which is about what a vacuum cleaner makes. My intention is to install my cyclone in my garage, which is adjacent to my shop and exhausting outside in back of my shop - that should lower the noise quite a bit also. I am concerned about bothering my neighbors though because their back porch and pool are right next to my garage. I was thinking if the garage gets too noisy, I might enclose the cyclone with some sound-deadening material and put a small fan in there to keep the motor cool - I don't know exactly how that will all work out, I'll just have to wait and see.</FONT></DIV> <DIV><FONT face="Verdana Ref" size=3></FONT> </DIV> <DIV><FONT face="Verdana Ref" size=3>I'm expecting to hear something akin to a freight train when I turn the thing on for the first time.</FONT></DIV> <DIV><FONT face="Verdana Ref" size=3></FONT> </DIV> <DIV><FONT face="Verdana Ref" size=3>As for the existing dust - I think the first step has to be to vacuum everything - many areas have a fairly thick layer of dust.

Moving that much air HAS to have a noise factor, IMO. As for clearing out the existing dust: Open all the doors & windows. Put a good mask on and have at it with the air compressor - every shelf - every nook and cranny. Mine gets that every 10 years or so.<G></DIV> <DIV>High ceilings help to keep the dust out of your face, BTW.</DIV> <DIV>Best Regards,</DIV> <DIV> </DIV> <DIV> </DIV> <DIV>Joe Garrett, R.P.T.
