Trusted Filtration Solutions Since 1998
Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a reliable manufacturer of high-performance filtration products. Our 30-40 Micron Phenolic Resin Fiber Filter Cartridge (4.5" OD, 20" Length, 60 GPM, 250 PSI) is engineered to deliver consistent, high-quality filtration for demanding industrial applications. With an annual export value exceeding US$5 million and a global presence across North America, South America, Europe, Asia, and Africa, we bring decades of expertise to every cartridge we produce.
Product Overview
This depth-type filter cartridge is constructed from phenolic resin-impregnated cellulose fibers, providing a rigid, high-strength structure that resists collapse under high differential pressure. The 30-40 micron nominal rating effectively captures suspended solids, sediments, and particulates, while maintaining a high flow rate of 60 GPM and a maximum operating pressure of 250 PSI. It is ideal for use in water treatment, chemical processing, food and beverage production, and oil/gas applications.
Key Features & Benefits
- Consistent Micron Retention: The 30-40 micron graded density structure ensures reliable particle capture from 30 to 40 microns, reducing the risk of downstream contamination.
- High Flow Capacity: Designed for 60 GPM, this cartridge minimizes pressure drop and supports high-volume processes without frequent replacements.
- Robust Construction: Phenolic resin bonding provides excellent mechanical strength and thermal stability, suitable for temperatures up to 180°F (82°C).
- Wide Chemical Compatibility: Resistant to most acids, alkalis, and organic solvents, making it compatible with a broad range of fluids.
- Easy Installation: Standard double open end (DOE) design fits most 4.5" OD housings; optional gasket end caps are available for sealed applications.
- Cost-Effective: Long service life and high dirt-holding capacity reduce replacement frequency and operational costs.

Detailed Product Description
Our phenolic resin fiber filter cartridges are manufactured using a controlled process that bonds cellulose fibers with phenolic resin under heat and pressure. This creates a rigid, deep-filtering matrix that traps particles throughout the entire cross-section of the cartridge, rather than just on the surface. The graded density design allows larger particles to be captured in the outer layers while smaller particles are retained deeper, maximizing dirt-holding capacity and extending service life.
The 30-40 micron range is ideal for pre-filtration and general purpose filtration where a balance between low pressure drop and fine particle removal is required. The cartridge can handle flow rates up to 60 GPM with a pressure drop of less than 2 PSI when clean, ensuring efficient operation in high-flow systems. With a maximum pressure rating of 250 PSI, it is suitable for use in pressurized lines and variable flow applications.
Applications
- Water Treatment: Municipal water, well water, RO pre-filtration, and wastewater.
- Chemical Processing: Acids, alkalis, solvents, and intermediate chemicals.
- Food & Beverage: Process water, beverages, syrups, and edible oils.
- Oil & Gas: Produced water, injection water, and fuel filtration.
- Industrial Manufacturing: Coolants, lubricants, and wash water.

Frequently Asked Questions (FAQ)
Q1: What is the typical lifespan of this cartridge?
A: The lifespan depends on the influent water quality and operating conditions. Under normal conditions (turbidity
Q2: Can this cartridge be used with hot water or steam?
A: Standard cartridges are rated for up to 180°F (82°C). For higher temperature applications (up to 250°F), we can customize the resin formulation. Please contact our sales team with your specific temperature requirements.
Q3: What end cap options are available?
A: We offer standard double open end (DOE) without gaskets. We also provide end caps with Buna-N, EPDM, or Viton gaskets for sealed applications. The gasket material should be selected based on chemical compatibility.
Q4: Is this cartridge suitable for drinking water?
A: Yes, the materials used are compliant with food-grade standards. The phenolic resin and cellulose fibers are safe for potable water filtration. However, we recommend confirming with local regulations; we can provide material safety data sheets upon request.
Q5: What is the recommended housing for this cartridge?
A: This cartridge fits standard 4.5" OD housings with a 20" length. Many commercial filter housings (e.g., those with 1" NPT connections) are compatible. We can recommend specific housings or provide a universal adapter if needed.
Q6: How do I dispose of a used cartridge?
A: Used cartridges may contain captured contaminants. Disposal should follow local regulations for industrial waste. The cartridge itself is primarily cellulose and resin, which can be incinerated in approved facilities. Check with your local waste management authority.
Q7: Can I get a sample before bulk order?
A: Yes, we offer samples for evaluation. Please contact us with your shipping details and any specific testing requirements. Sample lead time is typically 5-7 working days.
