ABSTRACT:
A filtration apparatus for an industrial vacuum system which includes a source of vacuum pressure, a collection vessel having an opening at one end for the collection of solid particulate matter and liquid waste material, and a conduit extending between the source of vacuum pressure and a second end of the collection vessel to apply the vacuum pressure to the collection vessel. A filtration chamber forms part of the collection vessel and is located between the two ends of the collection vessel. A filter media array is disposed in the filtration chamber, wherein the filter media array includes a plurality of non-woven or spun-bound pleated filter cartridges in at least two linear columns in the filtration chamber. In a preferred embodiment, control elements provide a maximum pressure differential across the body of the filter cartridges by providing an in-rush of ambient air into the filtration chamber when the pressure differential reaches a pre-determined quantity.
