High Performance (HP) Liquid Filter Bags High Performance (HP) Liquid Filter Bags

HP Filter Bags are tested in severe filtration conditions to perform in the most demanding applications. If you need a maximum performance bag, the MHP Series offers you 96% to 99% efficiency, depending on model. Our high-efficiency filter bags address diverse applications requiring removal of solids from liquids. They offer high particle-holding capacity, and are easy to install and replace.

All seams are fully welded, producing strong, reliable joints with no by-pass or loose sewing thread. Seams are both strong and flexible, allowing the filter bag to form to the restrainer basket. The seam edges are heat sealed, eliminating possible loose fibers. This results in a filter bag with durable performance for the most demanding applications.
