Series 500

High Performance Liquid Filter Bags

The 3M™ Series 500 High Performance Liquid Filter Bag which incorporates the patented 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 ft2 of usable filter media. Compare this with only 4.4 ft2 for most competitive filter bags and 0.65 ft2 for most competitive cartridges.

To make use of this entire surface area, the Series 500 Liquid Filter Bag is constructed using the patented Bypass/Transport concept invented by 3M researchers. 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.
