Products Description
The phenolic resin filter element is a thermoset-bonded depth cartridge engineered for consistent particulate control in aggressive, hot or viscous process fluids. Designed for predictable pressure behavior and minimal downstream contamination, it combines tailor-made porosity profiling with a mechanically robust resin backbone.
Technical parameters
| Media | Extended-length synthetic fibers bonded with a thermoset phenolic matrix (single-piece element). |
| Available nominal ratings | 1 µm - 200 µm (custom ratings available). |
| Standard lengths | 10″ (254 mm), 20″ (508 mm), 30″ (762 mm), 40″ (1016 mm) - other lengths on request. |
| Diameters | OD ~63–66 mm; ID options to suit industry housings. |
| Max continuous service temperature | up to 150 °C for high-temp variants. |
| Differential pressure | recommended change-out 2.5–4.0 bar (36–58 psi) depending on grade and temperature. |
| End options & seals | wide compatibility (flat cap, 222/226 o-ring, SOE/DOE) and seal materials including EPDM, Viton, PTFE. |

Selection & installation guidance
- Pick the right micron: Use coarser grades (25–150 µm) for bulk debris removal; use fine grades (1–10 µm) for final polishing.
- Match materials to chemistry: For aggressive solvents or elevated temperatures, specify high-temp resin grade and compatible gasket (e.g., Viton).
- Confirm flow vs ΔP: Provide target flow per cartridge and fluid viscosity so we can supply ΔP curves and predict service life.
- Housing compatibility: Confirm DOE/SOE configuration and any core-extender requirements before ordering.
FAQ
Q: How often should these filters be replaced?
A: Replacement frequency depends on contaminant load and operating conditions. Typically, filters should be replaced when differential pressure reaches 4 bar (58 psi).
Q: Can these filters be cleaned and reused?
A: While primarily designed as disposable filters, they can be cleaned using appropriate solvents for limited reuse in non-critical applications.
Q: What housing compatibility do you offer?
A: Standard 2.5" OD cartridges fit most industrial housings. Custom end configurations available for specific housing requirements.
