The Heavy Duty HEPA Vac attaches to a 55-gallon open-top drum, turning it into a HEPA-quality, industrial vacuum cleaner. It filters contaminants to HEPA requirements in dusty environments that require frequent cleaning. Extremely quiet at 82 dBA, the vac’s prefilter stops larger particles, while the HEPA filter handles the smaller ones. All filters are tested for minimum 99.97% filtration at the 0.3-micron level. The system includes the Heavy Duty Dry Vac, lever-lock drum lid, shutoff valve, prefilter, HEPA filter, 10-ft (3-m) static-resistant hose, hose hanger, ½-NPT quick-connects coupling, 20-ft (6-m) compressed-air hose, pressure gage, and aluminum chip wand (drum not included).
