Hi, I have 3-4 ivac clippers going at any one time and each is attached to their own shopvac. the noise is getting unbearable. we have tried boxing/inclosing the shopvacs, moving them under/inside counters/closets, etc and it is still just way too noisy. I am interested in some sort of central vac system that I can run one main trunk line with taps for each of the ivac and have just one main suction/disposal site. What have other busy shops used? Do I have to go with the true "clipper vac" type system or have any of you "McGyver" types tried something else that has been successful? ie: dust collector system, actual central vac system, etc???? Any and all feedback would be way appreciated!!
