That is a good company and unit. It is true you need vac also. Made my own system. Can't just use a shop vac IMO. You also need a big capacity compressor. 80 gal, 2 stage belt drive. Which will need 220V, 30A. More or less what Tim already said. I have a good blast cabinet and also blast big stuff outside.
