Ruwac Little Red WNS 2220 vacuumThe Ruwac Little Red WNS 2220 vacuum, aimed specifically at the concrete industry, is designed for picking up chips and fine dust, but can be adapted for use with vacuum-assist tools and pre-separation systems, as well as for point-of-source extraction. The vacuum uses a MicroClean filter rated at 99.9 percent efficiency at 0.5 microns. Large quantities of fine dust can be captured, says Ruwac, without loss of suction, and loose debris is dropped out of the filter to extend filter life and to reduce downtime. A large drop-down dustpan is foot-lever-operated to simplify debris removal.
