I have an older craftsman 16 gallon, 6 HP shop vacuum that has an ear piercing sound to it. My vacuum is in good shape and has impressive suction but the sound is way too loud. I hate to replace it if it can be sileneced somewhat.
I have seen a muffler made for central house vacuum's that appears to be made from an innner and outer pvc pipe. The inner pipe has holes drilled in it and is wrapped with fiberglass insulation. It is then inserted into the outer pipe. It looks similar to a glasspack muffler design.
I am unable to find information on how many decibels the muffler would drop the overall "noise". Has anyone here tried a muffler of this style?
Otherwise I may buy the Rigid WD1450 due to the many positive comments I have read about it.
Thanks, Joe
