A resin bonded filter engineered for rigid, non-shedding performance and high dirt-holding capacity — protects downstream membranes and precision equipment while extending service intervals in demanding industrial liquids filtration applications.
Unlike filters that are simply wound or melt-blown, our resin bonded filters are built through a proprietary process where the depth filtration media is impregnated and permanently bonded with a thermosetting epoxy resin. This creates a monolithic, porous matrix that cannot delaminate or compress, even under cyclic pressure loads. The result is predictable, consistent performance throughout the entire service life, with no risk of media shedding to compromise sensitive equipment like membrane elements or precision nozzles.

✅ Structural stability that prevents media migration
The thermoset resin locks media fibers into a single, non-delaminating matrix. In practice this means no fiber shedding during CIP, pressure spikes or when upstream conditions vary - a critical risk reduction when protecting membranes or dosing equipment.
✅ High usable dirt-holding
A gradient pore profile captures large particles deep inside the cartridge and finer particles further downstream. That uses the full media volume (not just the surface), extending run-time and reducing change-out frequency.
✅ Maintains flow under load
High void volume (>85%) plus rigid pore structure gives a stable pressure drop profile as the cartridge loads. The result: predictable flow rates and fewer emergency interventions.
✅ Broad chemical resilience
The epoxy-bonded acrylic/polyester matrix is compatible with many aqueous acids/alkalis and with a range of oils and solvents (select grade and seals appropriate to the fluid).
Beta ratio: βx ≥ 1000 at the rated micron (production validated).
Initial pressure drop: < 0.35 bar at 10 L/min (10" cartridge, water, 20 °C).
Dirt holding: > 55 g standardized dust per 10" cartridge (ISO 2941 protocol, representative grade).
Temperature & pressure: Rated to 121 °C and 4.8 bar continuous ΔP; short-term allowances at higher ΔP available per grade.
