High capacity filter bags provide consistent filtration of fluids in a wide variety of applications. The random interlocking of micro-denier felt fibers provides efficient depth filtration at increased flow rates. Felt filter bags are best utilized in process streams with contaminants of a broad particle size distribution or where gels are present. Rigid internal quality control standards help to assure consistent and repeatable filtration performance over time.
Felt filter bags are available in four different materials of construction providing excellent compatibility with a wide range of process fluids. Various optional surface treatments are offered to reduce fiber migration and enhance filtration performance. An all thermally welded polypropylene felt bag is available for higher purity applications. Felt filter bags are manufactured in a wide range of sizes and configurations to fit most bag filter housings.
• High flow rates at low pressure drops.
• High contaminant holding capacity.
• Nominal retention ratings from 1 to 200 µm.
• Polyester, Nylon, Polypropylene, or Nomex ® filter media offered for use in a wide array of chemicals and operating temperatures.
• Bag sizes and sealing configurations available to fit most industry standard bag housings.
• Thermally welded polypropylene version for high purity applications.

High performance mesh liquid filter bags provide efficient and reliable filtration of fluids in a wide variety of applications. Filter bags are constructed with a proprietary range of woven filter media in two fiber grades: multi-filament bags and mono-filament bags.
Multi-filament bags are manufactured from fiber strands consisting of thousands of micro-denier interwoven fibers. The strands are woven in a specific pattern to create a very uniform pore structure across the filter bag. The result is an economical filter bag that provides consistent filtration performance.
Mono-filament filter bags provide an exceptional degree of uniformity and mechanical strength. The filter media is manufactured into a mesh in which each strand is a single fiber. The fibers are woven into a precise pattern and thermally bonded to enhance mechanical strength. As a result of their construction, these mesh filter bags are ideally suited for filtration applications that require sharp particle cut-offs for the sieving or classification of hard particles.
Mesh filter bags are available in a wide range of sizes and sealing configurations to fit most bag filter housings.
• Uniform filter media provide very consistent performance and high solids loading capacity.
• Multifilament mesh bags offer low cost, disposable filtration with woven media.
• Monofilament mesh bags provide precise filtration and exceptional strength.
Fibers will not shift or deform under pressure or in use with viscous fluids.
• High flow rates at low pressure drops with high solids loading capacity.
• Retention ratings available from 5 to 800 µm.
• Polyester, Nylon or Polypropylene filter media offered for use in a wide array of
chemicals and operating temperatures.
• Bag sizes and sealing configurations available to fit most industry standard bag
housings. Injection molded polypropylene flange with handles are standard on
mesh bags.
