Dustless Technologies expands its line of dust control systems to include industrial grade HEPA vacuums for large-scale concrete construction and wood flooring applications. The new line of vacuums includes three models: the Pro Series 200, Pro Series 300 and Pro Series 600. Each model number reflects the cfm of the vacuum. The cyclone design captures 98-percent of dust particles before they reach the HEPA filter, greatly extending cleaning intervals.
