Our 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 four times more service life.

Our 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 Our 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 minimise 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 • Maximises utilisation 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
