Portable dust vacuum

The Pulse-Bac PB-550 from CDCLarue Industries is a portable compact dust vacuum for hand tools, designed to collect dust and debris generated by hand tools used to cut, grind or sand. Only 25 inches tall and 16 inches in diameter, the unit can generate more than 121 cubic feet per minute of air flow, with 74 inches of lift. The PB-550’s advanced filter filtration system uses a two-stage filtration process in compliance with 2010 EPA mandatory standards for dust control when using power tools to cut, grind or sand.
