The CPS CAT 5 Electric Dust Extractor is a 480 volt 400 CFM full-sized industrial dust extractor. Its primary filter, with non-stick coatings, help to prevent filter blinding and motor overheating. It also has a unique backwash system where 100% of backwash goes directly to the bag. The OSHA compliant HEPA filter has three times more usable surface area than standard industry dust extractors. It also utilizes Longopac continuous bagging system for zero airborne dust change changing bags. The CAT 5 has an optional distribution box allowing the grinder to be connected to the dust extractor and the dust extractor connected to the power source, allowing for better cord management.
