Camfil Farr Air Pollution Control’s pulse-cleaned industrial vacuum with dual-stage HEPA filtration drastically minimizes clogs, preventing the problems that result from loss of suction during cleaning, according to the manufacturer. Called the FarrVac Junior, it uses a patented pulse-cleaning technology that works without compressed air. Filters are cleaned every 10 seconds, preventing clogging. The unit may be used for everyday shop cleanup or as an accessory to an installed dust collector when replacing or emptying dust drawers or drums. The FarrVac Junior vacuum comes equipped with durable spun bond polyester filters that last up to 10 times longer than conventional filters. Two primary HEPA filters provide 99.97 percent efficiency on dust particles to 0.3 micron. The unit has a 120 cfm motor and operates on 120VAC, 50/60 Hz power. It comes equipped with an 8-gallon tank, hose, hard floor wand kit and optional aluminum wand and floor sweep. A cyclonic housing design minimizes filter exposure to debris.
