Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5 Million – US$10 Million. Our Factory Tested Sintered Phenolic Resin Filter Cartridge is a premium filtration solution designed for demanding industrial applications. Each cartridge undergoes 100% quality check before shipment and is backed by a 1-year warranty, ensuring reliable performance and peace of mind. Available in micron ratings from 5 to 50 microns, this cartridge delivers consistent filtration efficiency for a wide range of liquids and gases.
Our sintered phenolic resin filter cartridges are manufactured using a proprietary process that bonds phenolic resin with high-quality fibers, creating a rigid, porous structure that resists collapse and chemical attack. The result is a durable, depth-type filter that provides high dirt-holding capacity and long service life. Below are the key features and technical specifications that make this product a preferred choice for engineers and procurement professionals worldwide.
Key Features & Benefits
- Sintered Construction – The phenolic resin is thermally fused to create a robust, seamless matrix that resists channeling and media migration, ensuring consistent filtration efficiency over the entire cartridge life.
- Wide Micron Range (5–50 µm) – Available in multiple nominal ratings to meet specific process requirements, from fine polishing to coarse pre-filtration.
- 100% Factory Tested – Every cartridge is individually inspected for integrity, flow rate, and pressure drop, guaranteeing that you receive only defect-free products.
- 1-Year Warranty – We stand behind our manufacturing quality with a comprehensive warranty, covering defects in materials and workmanship under normal use conditions.
- High Temperature & Pressure Tolerance – Suitable for operating temperatures up to 120°C (248°F) and differential pressures up to 4.2 bar (60 psi).
- Chemical Compatibility – The phenolic resin matrix offers excellent resistance to a wide range of chemicals, including acids, alkalis, solvents, and hydrocarbons.
- Low Migration & Clean Running – Minimal fiber or resin release during operation, protecting downstream equipment and processes.
- Customizable Dimensions – Available in standard lengths (10", 20", 30", 40") with outer diameters of 2.5" and inner diameters of 1" or 1.5". Non-standard sizes can be produced upon request.

Applications
- Process water filtration (cooling towers, boiler feed, RO pre-treatment)
- Chemical processing (acids, caustics, solvents, electroplating baths)
- Food & beverage (syrups, juices, edible oils, beer, wine)
- Pharmaceutical & cosmetic (intermediate and final product filtration)
- Petrochemical & refining (process streams, amine solutions, catalysts)
- Wastewater treatment (industrial effluent polishing)
The sintered phenolic resin structure provides a true depth filtration mechanism, trapping particles throughout the thickness of the cartridge. This results in higher dirt-holding capacity compared to surface-type filters, reducing the frequency of cartridge changes and lowering overall operating costs. Additionally, the rigid construction allows the cartridge to withstand high differential pressures without collapsing, making it ideal for high-viscosity fluids or applications with frequent pressure surges.
Our 100% quality check includes visual inspection, dimensional measurement, and flow/pressure testing on each cartridge. This rigorous process ensures that every unit meets our strict standards before being packed for shipment. We also offer custom packaging options, including bulk packing with poly bags, individual boxes, or export cartons, to suit your logistics needs.

Frequently Asked Questions
- What is the maximum temperature this cartridge can handle? The cartridge can operate continuously at temperatures up to 120°C (248°F). For higher temperatures, please consult our technical team for custom solutions.
- Can these cartridges be cleaned and reused? Sintered phenolic resin cartridges are typically single-use disposable items. However, they can be backwashed or cleaned in some applications to extend service life. We recommend testing under your specific conditions.
- What end cap configurations are available? Standard end caps include open-ended (DOE) with flat gaskets, 222 O-ring, 226 O-ring, and bayonet styles. Non-standard ends can be custom-made.
- How do I choose the correct micron rating for my application? The choice depends on the particle size you need to remove. For fine filtration, use 5–10 µm; for general polishing, 20–30 µm; for pre-filtration, 40–50 µm. Our sales team can help you select the right rating.
- What is the typical shelf life of these cartridges? When stored in a cool, dry place away from direct sunlight and extreme temperatures, the cartridges can be stored for up to 3 years without degradation. Each cartridge is individually sealed in a poly bag for protection.
- Do you offer free samples for testing? Yes, we are pleased to provide free samples for evaluation. Please contact us with your requirements and shipping details, and we will arrange a sample shipment.
- What is the minimum order quantity (MOQ)? Our standard MOQ is 50 pieces per micron size and length. For smaller quantities, please inquire about our stock availability.
- How long is the delivery time? For standard sizes, delivery is typically 15–25 working days after order confirmation. Custom sizes may require 30–45 working days, depending on quantity.
