Liquid Bag Filters

Liquid Bag Filters

Liquid bag filters help remove particulate from process liquids and protect downstream equipment. They are a highly effective solution for removing dirt, debris, and contaminants from process fluids. We offer many options for bag filters, from economical filter socks to high-efficiency pleated filter bags.

These filters directly protect downstream rotating equipment, reduce maintenance costs and ensure consistent fluid quality for demanding industrial applications such as aerospace, water, coolants, chemicals, fuel cells, paints or inks and general industrial liquid filtration. SC Industrial Sales offers liquid filtration bags to help you maintain the quality of process fluids.

Finding the Right Liquid Filter Bag Media Option for Your Process

Media options for liquid filter bags include polypropylene, polyester, Nomex and Teflon. By combining the proper fiber diameters, weights and thicknesses, you can achieve an economical depth filter media. The benefits of standard and high-efficiency options include:

  • Standard felt bags: Polyester and polypropylene felt bags are economical, versatile options for general-purpose depth filtration.
  • High-efficiency microfiber bags: These are ideal for applications requiring absolute-rated filtration, superior oil-absorbing capabilities and longer changeout intervals. The optional addition of a needle-punched felt layer provides a prefilter zone and extends life.
  • Extended surface pleat (ESP) bags: ESP bags maximize dirt-holding capacity and flow rates without modifying existing standard-size #2 housings.
  • Mesh bags: Mesh is typically considered a better option for coarser straining and surface filtration.

Materials, Micron Ratings and Custom Construction

The following specifications allow buyers to customize their filtration setup for compatibility and performance.

  • Available micron ratings: Micron ratings range from sub-micron up to 800+ microns, depending on whether you choose felt, microfiber or mesh.
  • Sealing and ring options: Fully welded seams reduce the risk of bypass and are available in polypropylene and polyester felt for #1, #2, #3, #4 and #5 bag sizes with plastic flanges. Steel rings or plastic flanges ensure a secure fit across various housing styles.
  • Strict compatibility requirements: Materials must meet compatibility requirements, including silicone-free construction and FDA compliance for food-contact applications (CFR 21, Section 177.1520).
