    Details

    The 3M™ DF series filter element is a proven alternative to most conventional bag filters. Our filter is a true graded porosity media structure that provides a 62% increase in surface area compared to a standard #2 bag and up to 4 times more service life.

    The 3M™ DF series filter media consists of 2 layers with the first layer being “open” to remove the larger contaminants while the second layer is “tighter” to remove the smaller contaminants. Our graded porosity structure provides greater contaminant holding capacity and longer life than conventional single layer media. Compared to conventional felt filter bags, 3M DF series filter element provide up to 4 times the service life, superior contaminant reduction efficiency, enhanced flow per filter and reduced losses associated with frequent filter change-outs.

    Geometry

    The 3M DF series filter element consists of two cylinders bonded to a top plate and a lower seal plate. As fluid enters the top of the filter through flow channels in the top plate, it flows between the inner and outer media cylinders. Then it passes through the media and support basket and into the clean chamber of the filter housing. Our design incorporates an innovative geometry of both bag filter and restrainer basket, giving complete 3-dimensional support of the media. This eliminates the potential for bag filter rupture and the resulting gross contamination of the downstream effluent. The 3M DF series filter element design reduces hold-up fluid volume by 67% compared to conventional filter bags, which helps minimize worker exposure to process fluids due to less frequent bag change-outs.

    3M™ DF Series Filter Best Features



    100% downstream support of the filter element



    Eliminates filter rupture, contaminant bypass and unloading

    Allows operation to higher differential pressures before filter change-out


    Superior flow characteristics



    Maximizes utilization of filter surface area and maintains low operating pressure drop

    Reduces flow per unit area (flux) for improved effluent quality



    Greater media surface area



    Achieves up to four times the service life as compared to conventional filter bags

    Improves the retention efficiency of the bag filter



    Greater contaminant holding capacity



    Media layers of different porosities are combined to form a graded porosity structure

    Each nominally rated filter medium has been optimized to achieve the longest service life

    We use advanced thermal sealing processes to weld the side seams to form the bag and secure the sealing ring. Thermal-singe treatment of the exterior surface prevents material fibers from migrating into the clean filtered process media. Each grade of the 3M™ DF series filter element is manufactured from high performance fibers that are selected, based on extensive media performance testing. No adhesives, binders or silicone are used in the manufacturing processes.
