Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with annual export value of US$5-10 million, proudly presents our 20 Inch Sintered Phenolic Resin Filter Cartridge 1 Micron 222 O-Ring High Pressure 0.6 MPa. This cartridge is engineered for demanding filtration applications where high dirt-holding capacity, superior chemical resistance, and consistent performance under high pressure are required. Made from advanced sintered phenolic resin, it offers a robust structure that withstands repeated cleaning and harsh operating conditions, making it a cost-effective solution for industries ranging from water treatment to petrochemical processing.
Key Features & Technical Specifications
- High Precision Filtration: 1 micron absolute rating ensures removal of fine particles, sand, silt, and sediment, delivering clean output for critical processes.
- Robust Sintered Construction: The phenolic resin matrix is thermally bonded, creating a rigid, depth-type filter medium with high porosity and mechanical strength.
- High Pressure Capability: Rated for 0.6 MPa (6 bar) continuous operation, suitable for high-flow and high-pressure systems without deformation or collapse.
- 222 O-Ring Connection: Standard 2-inch (222) O-ring seal ensures leak-free installation in most housings and compatibility with global filter systems.
- Chemical Resistance: Resistant to a wide range of chemicals including acids, alkalis, and organic solvents, ideal for industrial process filtration.
- Long Service Life: The sintered structure allows for backwashing and repeated cleaning, significantly reducing replacement frequency and operational costs.
- Temperature Stability: Operates reliably up to 60°C, suitable for hot water and moderate temperature applications.

Advantages Over Competing Technologies
- Compared to string-wound or melt-blown cartridges, the sintered phenolic resin structure offers higher dirt-holding capacity (up to 3-5x more) and better resistance to channeling.
- Unlike pleated or membrane filters, this depth-type cartridge can be backwashed and reused multiple times, lowering total cost of ownership.
- Excellent tolerance to pressure surges and water hammer due to rigid monolithic design.
- Compatible with aggressive chemicals where polypropylene or nylon filters would degrade.
- Available with various end cap configurations (222 O-Ring, 226 O-Ring, flat cap, etc.) to fit most commercial housings.
Typical Applications
- Municipal and industrial water treatment – pre-filtration for RO systems, iron removal, sand filtration.
- Chemical processing – filtration of acids, alkalis, solvents, and plating solutions.
- Oil & gas – produced water filtration, injection water treatment.
- Food & beverage – process water, syrup, and edible oil filtration.
- Pharmaceutical – high-purity water and intermediate filtration.
- Cooling tower water and wastewater reuse.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum operating temperature of this cartridge?
A: The recommended maximum continuous operating temperature is 60°C (140°F). Brief exposure up to 80°C may be acceptable but is not recommended for prolonged use. -
Q: Can this cartridge be cleaned and reused?
A: Yes, the sintered phenolic resin structure allows for backwashing with clean water or a mild chemical cleaning solution. Typically, 3-5 regeneration cycles are possible before replacement is needed. -
Q: What is the difference between 222 O-Ring and 226 O-Ring?
A: The 222 O-Ring is a standard 2-inch diameter seal with a flat face, while the 226 O-Ring has a bayonet-style lock. Our cartridge is 222 O-Ring; other configurations are available upon request. -
Q: Is this cartridge suitable for potable water?
A: Yes, the materials used are food-grade and comply with FDA and NSF standards for drinking water applications. Please contact us for specific certifying documents. -
Q: What is the pressure drop at 1 micron filtration?
A: The initial clean pressure drop is approximately 0.2-0.3 bar (20-30 kPa) at 1 m³/h flow rate for a 20-inch cartridge. The actual pressure drop depends on water viscosity and flow rate. -
Q: Do you offer custom lengths or diameters?
A: Yes, we can customize the length (e.g., 10, 30, 40 inches) and outer diameter (up to 4 inches) according to your housing specifications. Minimum order quantity may apply. -
Q: How should I store the cartridges?
A: Store in a cool, dry place away from direct sunlight. Keep the original packaging or sealed plastic bags to prevent contamination. Shelf life is at least 3 years. -
Q: What is the minimum order quantity (MOQ) for this product?
A: For stock standard sizes, MOQ is 50 pieces. For custom specifications, MOQ may be 200-500 pieces. Samples are available for testing with a small fee.
