Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with over 26 years of expertise in filtration solutions. Our Sintered Phenolic Resin Filter Cartridge, 5 Micron, 250°F Max Temp, 150 PSI Rated, 304 Stainless Steel Core is engineered to deliver exceptional performance in demanding industrial applications. Combining the chemical resistance of phenolic resin with the structural integrity of a 304 stainless steel core, this cartridge offers a reliable and cost-effective solution for removing particulates as small as 5 microns. Whether you need to filter water, chemicals, oils, or beverages, our cartridge ensures consistent flow rates and long service life, reducing downtime and maintenance costs.
As a manufacturer with annual export value between US$5 million and US$10 million, we serve markets across North America, South America, Europe, Asia, Africa, and Oceania. Our products are shipped from major ports including Tianjin, Qingdao, Shanghai, and Foshan, ensuring timely delivery to global customers. Below we detail the key features, technical specifications, and benefits of our sintered phenolic resin filter cartridge.
Product Features & Benefits
- High Filtration Efficiency: 5 micron absolute rating ensures removal of fine particles, including sand, silt, rust, and scale, providing clean output for sensitive processes.
- Temperature Resistance: Rated for continuous operation up to 250°F (121°C), suitable for hot water, steam condensate, and high-temperature chemical applications.
- Pressure Durability: Withstands up to 150 PSI (10.3 bar) differential pressure, making it robust for high-flow and high-pressure systems.
- 304 Stainless Steel Core: Provides excellent corrosion resistance and structural rigidity, preventing collapse under high pressure and extending cartridge lifespan.
- Sintered Phenolic Resin Construction: Offers superior chemical compatibility with acids, alkalis, solvents, and hydrocarbons, while maintaining low extractables and taste/odor neutrality.
- Deep Depth Filtration: The sintered structure creates a tortuous path for particles, capturing contaminants throughout the entire cross-section rather than just on the surface, leading to higher dirt-holding capacity and longer service intervals.
- Easy Installation & Replacement: Standard industry dimensions (available in 10, 20, 30, 40 inch lengths) with double open-end (DOE) or 222/226 O-ring configurations for compatibility with most housings.
- Cost-Effective: Reduced frequency of cartridge changes due to high dirt-holding capacity and robust construction, lowering overall operating costs.

Applications
- Water Treatment: Industrial process water, cooling tower water, reverse osmosis pre-filtration, and wastewater polishing.
- Chemical Processing: Filtration of acids, bases, solvents, and specialty chemicals where high chemical resistance is required.
- Petroleum & Oil: Crude oil, diesel, lubricants, and hydraulic fluids — the 304 SS core withstands aggressive fluids.
- Food & Beverage: Beverage clarification, edible oil filtration, and syrup processing — compliant with food-grade standards.
- Pharmaceutical: Pre-filtration for water for injection (WFI) and process intermediates where low extractables matter.
Why Choose Our Sintered Phenolic Resin Filter Cartridge?
Unlike traditional string-wound or melt-blown cartridges, our sintered phenolic resin construction provides a uniform pore structure that eliminates media migration and channeling. The 304 stainless steel core adds mechanical strength, allowing the cartridge to handle high differential pressure without collapsing. This combination results in a longer service life — up to 2–3 times longer than standard polypropylene cartridges in similar applications — reducing the frequency of changeouts and labor costs.
Additionally, the phenolic resin matrix is inherently hydrophobic, which helps resist bacterial growth and swelling in wet environments. This makes the cartridge especially suitable for humid or high-temperature operations where organic media would degrade quickly.

Frequently Asked Questions (FAQ)
Q1: What is the difference between sintered phenolic resin and melt-blown cartridges?
A: Sintered phenolic resin cartridges are made by compressing and heat-treating resin particles to form a rigid, porous structure. They offer higher chemical resistance, temperature tolerance, and mechanical strength compared to melt-blown polypropylene. They also have a deeper filtration depth, providing higher dirt-holding capacity.
Q2: Can this cartridge be used for hot water up to 250°F?
A: Yes, the cartridge is specifically rated for continuous operation up to 250°F (121°C). However, at higher temperatures, the pressure rating may be derated. Please consult our technical team for specific application conditions.
Q3: Is the 304 stainless steel core food-grade?
A: 304 stainless steel is a common food-grade material. Our cores are manufactured from high-quality 304 SS and are suitable for food and beverage applications. We can also provide 316L cores upon request for higher corrosion resistance.
Q4: What end cap configurations are available?
A: We offer Double Open End (DOE), 222 O-Ring, and 226 O-Ring configurations. Other custom end caps can be made to order. Please specify your housing requirements when ordering.
Q5: How often should the cartridge be replaced?
A: Replacement frequency depends on the contaminant load and flow rate. Typically, when the differential pressure across the cartridge reaches 30–40 PSI, or when the flow rate drops significantly, it is time to replace. Our cartridges have a high dirt-holding capacity, often lasting 6–12 months in moderate applications.
Q6: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard sizes is 50 pieces. For custom lengths or special end caps, we require a minimum of 100 pieces. Sample orders are available for evaluation.
Q7: Do you provide certifications or test reports?
A: We can provide material certificates, dimensional inspection reports, and pressure testing data upon request. Please note that we do not claim third-party certifications unless explicitly agreed.
Q8: What is the lead time for mass production?
A: For standard cartridges, lead time is 10–15 days after order confirmation. For custom orders, it may be 20–30 days depending on the complexity. We can expedite urgent orders upon request.
