I have a couple of iVac Pro Modules that run 110 volt shop vacs and they work great. They are tied to router tables, chop saws, and etc. I would like to bump up the dust collector size to a 220 volt system. I just discovered that the manufacturer makes a switch for heavier wiring. When I search out the re-sellers for the 220 volt system nobody seems to have inventory. Either this is the neatest thing since sliced bread and they can't keep them in stock or else there are too many warranty issues to resolve and they no longer carry them. Does anybody have any experience with the 220 volt version and/or does anybody know where to buy these?
From Contributor B:
You could get the best info from an electrician. I have a 3ph 5 hp collector. There is a main switch that actually turns the collector on. Throughout the shop are door bell-type push button switches that tell the main switch to come on. They are not automatic but they can be put everyway at low cost and with low voltage wire.
