We designed the 3M™ Series 500 High Performance Liquid Filter Bags to incorporate our proprietary bypass and transport layer design that maximizes the amount of surface area in each bag. The result is a unique filter designed to improve performance and reduce operating costs. The 3M filter contains up to 38 square feet of usable filter media.
Compare our 38 square feet of usable filter media with only 4.4 square feet for most competitive filter bags and 0.65 square feet for most competitive cartridges. To make use of this entire surface area, we constructed the Series 500 Liquid Filter Bag using the patented Bypass/Transport concept invented by our 3M researchers. We cut specially designed bypass holes into certain areas to prevent premature blinding of the filter. In conjunction with the bypass design, a second media, called a transport layer, helps to distribute fluid flow evenly through the filter. The outer layers provide a highly uniform barrier for final particle filtration. This construction results in very high dirt loading capacity, even at high flow rates. Welded Side Seams form the bag and secure the sealing ring. Because there are no sewn holes there is no particle by-pass through the seam. State-of-the-art procedures are then used to properly weld the seams and affix the media to the collar and form a complete, cohesive filter with no holes from sewing.
Filter Media
Meltblown polypropylene microfiber filter media provides high particle removal efficiency for high quality filtration with broad chemical compatibility. We use no silicone in materials of construction or in manufacturing these products.
