Designed for reliable pre-filtration, Spun Nominal filters feature multilayer fiber construction with high
dirt-holding capacity. These cost-effective filters are ideal for general clarification, membrane protection, and water pre-treatment in food, pharma, and chemical processes.
Explore the range
Built for more demanding applications, Spun Absolute filters are made from thermally bonded media with clearly defined removal ratings (β > 5000). Their zoned construction provides depth loading with precision retention - making them suitable for membrane pre-filtration and final protection steps.
- Unique Construction
- Key Features & Benefits
- Media Compatibility
- Applications
Spun Bonded filters are built using a graded fiber structure that allows progressive particle capture from the outer to the inner layers, enabling depth filtration with low pressure drop and longer service life. Spun Nominal versions provide economical and effective clarification, while the Spun Absolute design features multiple filtration zones that achieve precise retention and maintain high flow rates even under variable conditions. Thermally bonded construction prevents fiber shedding, ensuring media integrity and compatibility with a wide range of chemicals and cleaning agents. One-piece construction further improves mechanical stability, while optional internal cores provide added strength for demanding setups.
- High Dirt Holding Capacity: The multilayer fiber structure captures particles across the depth of the filter, which helps extend service life and reduces filter changeouts in particle-heavy applications.
- Tailored Retention Performance: Available in nominal or absolute-rated versions, the filters can be matched precisely to the needs of your system, whether for general pre-filtration or critical protection.
- Extended Service Life: The design enables low differential pressure throughout the operating cycle, which supports longer filtration runs and improves process uptime.
- Stable Flow with Viscous Fluids: Even in systems using thicker liquids like syrups, oils, or coatings, the filter delivers consistent and reliable throughput.
- Flexible Sizing Options: Available in standard and extended lengths up to 40", these filters can be integrated easily into existing housings across multiple industries.
- Validated Process Compatibility: COC documentation is available where required, making these filters suitable for use in validated or regulated production environments.
- Reinforced Construction Option: While filters are coreless by default, a rigid inner core can be added to enhance mechanical strength under pressure or temperature variation.
- Wide Chemical Resistance: The filters are compatible with a range of process fluids, including solvents, cleaning agents, and chemical intermediates.
- Base Materials: The filters are constructed from polypropylene or nylon fibers, chosen for their mechanical strength and chemical compatibility.
- Optional Variations: Configurations using PET (polyester), nylon blends, or enhanced polypropylene are available to meet higher temperature or chemical demands.
- Regulatory-grade Construction: All materials are FDA-listed and produced in a single-piece design, suitable for food contact and compliant with industry standards.
- Membrane Pre-filtration: Used ahead of final sterile filters to reduce bioburden and extend service life of critical downstream filtration.
- Biotech and Pharmaceutical Production: Ideal for buffer prep, ingredient filtration, or intermediate liquid purification in GMP-regulated operations.
- Process Water Clarification: Removes suspended solids from rinse water, cooling systems, or feed water used in production processes.
- Chemical and Solvent Filtration: Suitable for paints, detergents, surfactants, and low-viscosity chemical formulations requiring particle removal.
- Beverage Processing: Supports clarification of water, juice, or flavoring compounds before final treatment or packaging.
