FDF Series:  Fine Dust Filter The (FDF) Fine Dust Filter combines the coarse filtration capability of a cyclone with the high efficiency of a bag filter. Its two-stage separation results in a compact filter that can operate efficiently even with very high loading. Pressure drops across the media remains low and less compressed air is needed for cleaning. Energy requirements are significantly reduced. Simple, Low Maintenance Operation Dust laden air enters the unit through a tangential inlet. An inner cylinder induces cyclonic flow, causing larger particles to separate from the air stream and fall into the hopper. The remaining fine particles collect on the filter elements. Periodically, the elements are cleaned by back-pulsing compressed air through a high efficiency pulsing system to maintain desired P. The cleaning system uses only 0.014 ncm (0.5 SCF ) of standard plant air per pulse. Clean air from inside the filter elements exits out the top of the unit.   FDF  product bulletin PDF >   Can't view PDF file? Click here > Features and Benefits Greater than 99% filtration efficiency. Pulse cleaning manifold is hinged, allowing easy access for filter element replacement. If headroom is tight, manifold can be removed. Filter can be mounted on the floor or suspended from the ceiling. The unit may be arranged for manual or automatic removal of the collected dust. Weighted bag cages prevent premature bag wear. Flex-Pleet™ filter cartridges may be substituted for filter bags to improve efficiency or abrasion resistance. Optional duct discharge cover allows outside or negative installation. Applications The FDF is a versatile filter with broad application in many industries: Textiles-by separately collecting fine dust from your lint and dust control system, the quality and value of fibrous waste is increased. Process industries-as a receiver on a dust relay line. Fume control at welding stations. Wood Processing-high grain loading filter for small plants or for adding incremental capacity [ back to top ]
