3M™ High Performance Liquid Filter Bag 525A incorporates a bypass and transport layer design that maximizes the amount of surface area in each bag.
3M™ High Performance Liquid Filter Bag 525A is designed to improve performance and help reduce operating costs. The filter contains up to 38 square feet of usable filter media. To make use of this entire surface area, 3M™ High Performance Liquid Filter Bag 525A is constructed using the bypass/transport concept, specially designed bypass holes are cut into certain areas of the filter media 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 of the filter provide a highly uniform barrier for final particle filtration. This construction results in very high dirt loading capacity, even at high flow rates. There are no sewn seams used in any of the filtering layers, thus allowing high filtration efficiencies for fine particles.
