- Unique Construction
- Key Features & Benefits
- Media Compatibility
- Applications
Each filter bag features a robust construction with a durable filtration media layer supported by either sewn or welded seams, depending on the performance requirement. A molded polypropylene collar or stainless steel ring ensures a secure fit inside housings, minimizing bypass and supporting leak-free operation. The multilayer felt or mesh structure enables high dirt-holding capacity while maintaining efficient flow, making them suitable for a wide range of particulate loads. Available in absolute or nominal retention ratings and optional depth-layer formats, these filters are optimized for quick change-outs and consistent filtration performance.
- Wide Filtration Range: Available in micron ratings from 1 to 1000 µm, supporting applications from coarse pre-filtration to fine particulate removal.
- Reliable Seam Integrity: Sewn or welded seams deliver strong mechanical durability, preventing bypass or media fatigue during operation.
- High-capacity Performance: The large surface area and deep filtration layers support excellent dirt retention and stable flow across long cycles.
- Versatile Contaminant Removal: Specialty bags available for oil removal and polymer absorption offer tailored solutions for targeted challenges.
- Easy System Integration: Designed to fit standard filter bag housings across multiple industries, allowing seamless implementation.
- Minimized Maintenance: Fast, clean change-outs reduce downtime and labor costs while maintaining hygiene and process uptime.
- Standardized Sizing: Offered in industry-standard diameters and lengths for universal compatibility with minimal customization.
- Polypropylene Needle Felt: A common choice for broad compatibility and general-purpose filtration in food, pharma, and chemical applications.
- Polypropylene Multilayer: Provides enhanced depth and higher dirt-holding capacity for demanding pre-filtration setups.
- Polyester Needle Felt: Used where higher mechanical strength or elevated temperature resistance is required.
- Nylon Needle Felt: Offers fine particulate control with excellent abrasion resistance and consistent retention.
- Polypropylene MO: Designed for oil-absorbent applications in hydrocarbon-rich or emulsified fluid systems.
- Nylon MO: Ideal for solvent or chemical processes where oil removal is a primary concern.
- Bulk Liquid Filtration: Frequently used in biotech, food, and pharmaceutical industries for high-volume pre-filtration or clarification.
- Chemical and Solvent Processing: Efficient in removing particulates from acids, bases, and organic solvents in manufacturing lines.
- Membrane Pre-filtration: Acts as a protective layer to reduce fouling and extend life of downstream fine or sterile filters.
- Water and Wastewater Treatment: Applies to utility and discharge water systems for removal of sediment, debris, and other solids.
- Paints, Coatings, and Inks: Ensures clarity and uniformity in viscous products by removing agglomerates, grit, or undispersed materials.
