Replacement Filter Bag set of 14 fits the ARBE DC-800 dust collector (our 60B 854-1370) as well as the original 60U dust collectors.  These ultra-weave filter bags are manufactured with a unique entanglement process that blends their fibers, creating a more uniform material with a smaller pore size providing better surface loading of dust and preventing penetration deep into the media. The better surface loading, means these ultra-weave bags provide improved cleaning and a lower pressure drop, which results in greater energy savings and greater filtration efficiency.
