The Pro 311 is an industrial grade vacuum designed to collect, capture and control dust and debris generated by surface preparation equipment and manufacturing machinery. Our revolutionary design in vacuum filtration automatically flushes the filters clear while you work, using only ambient air and vacuum.

Just turn it on and go to work, Pulse-Bac® technology does the rest.
