Anping County Boli Hardware Wiremesh Products Factory, a professional manufacturer established in 1998, proudly presents our 20 Inch Sintered Phenolic Resin Filter Cartridge with a 1 micron rating and a 304 SS inner core, capable of withstanding 220°C thermal resistance. Engineered for demanding filtration applications, this cartridge combines high-temperature stability with exceptional chemical resistance, making it an ideal choice for aggressive fluid filtration in industries such as petrochemical, pharmaceutical, and industrial water treatment. Our decades of manufacturing experience ensure consistent quality and reliable performance that meets the rigorous standards of global buyers.
This filter cartridge is constructed from sintered phenolic resin, a material known for its excellent flexibility, high dirt-holding capacity, and resistance to a wide range of chemicals including acids, alkalis, and organic solvents. The 304 stainless steel inner core provides robust structural integrity, preventing collapse under high differential pressure and ensuring long service life. The 1 micron filtration grade offers fine particle removal, suitable for polishing and clarification processes. With a maximum operating temperature of 220°C, it outperforms many standard polypropylene or nylon cartridges in high-temperature environments.
Key Features & Benefits
- High Temperature Resistance: Operates continuously up to 220°C (428°F), ideal for hot oil, steam condensate, and high-temperature chemical filtration.
- Chemical Compatibility: Resistant to most acids, alkalis, and solvents, ensuring compatibility with aggressive media.
- Robust Mechanical Strength: 304 SS inner core prevents deformation and collapse, maintaining consistent filtration efficiency even under high differential pressure.
- High Dirt-Holding Capacity: Sintered phenolic resin structure provides deep filtration with large void volume, extending service life and reducing replacement frequency.
- Low Abrasion & No Media Migration: Bonded fibers minimize particle shedding, delivering clean filtrate.
- Standard 20-inch Length: Compatible with most standard filter housings; custom lengths available upon request.
- Easy Installation: Double Open End (DOE) design fits standard 2.5-inch outer diameter housings.

Compared to traditional melt-blown or string-wound cartridges, our sintered phenolic resin cartridge offers superior performance in high-temperature and chemically aggressive environments. The 304 SS inner core not only adds mechanical strength but also eliminates the risk of core corrosion or collapse, common with plastic cores. This design ensures consistent filtration efficiency and long-term reliability, reducing downtime and maintenance costs for your operations.
We understand that every application has unique requirements. Therefore, we offer customization options including various micron ratings (0.5-100 µm), different lengths (10", 30", 40", etc.), and alternative end cap styles (flat gasket, spear, etc.). Our experienced engineering team can help you select the optimal configuration for your specific process.

Frequently Asked Questions
Q1: What is the maximum temperature this cartridge can withstand?
A: The cartridge is rated for continuous operation up to 220°C (428°F). Brief exposure to slightly higher temperatures may be acceptable, but we recommend staying within the rated limit for optimal performance.
Q2: Is the 1 micron rating absolute or nominal?
A: The 1 micron rating is nominal. For absolute filtration requirements, we can provide cartridges with a specified beta ratio (e.g., β1000 ≥ 1 µm). Please contact our sales team for detailed specifications.
Q3: Can this cartridge be used with organic solvents?
A: Yes, the sintered phenolic resin material is resistant to many organic solvents, including alcohols, ketones, and aromatic hydrocarbons. However, we recommend testing compatibility with your specific solvent or consulting our technical team.
Q4: What is the advantage of a 304 stainless steel inner core over a plastic core?
A: A 304 SS core provides superior mechanical strength, preventing collapse under high differential pressure or during backwashing. It also resists corrosion and is compatible with high-temperature and aggressive chemical environments, ensuring longer service life and consistent performance.
Q5: What are the available end cap configurations?
A: Standard is Double Open End (DOE) with a 2.5-inch outer diameter. We also offer options such as flat gaskets, spear ends, and custom adapters to fit various housings. Please specify your housing type when ordering.
Q6: How do I install this cartridge?
A: The cartridge is designed for easy installation in standard 2.5-inch OD filter housings. Simply remove the old cartridge, insert the new one ensuring the open ends align with the housing seals, and tighten the housing. No special tools are required.
Q7: What is the typical lifespan of this cartridge?
A: Lifespan depends on the contaminant load and operating conditions. Thanks to the high dirt-holding capacity of the sintered phenolic resin, the cartridge often lasts 1.5 to 3 times longer than standard melt-blown cartridges in similar applications. We recommend monitoring differential pressure for replacement timing.
Q8: Do you offer custom lengths or micron ratings?
A: Yes, we can manufacture cartridges in lengths from 10 to 40 inches and micron ratings from 0.5 to 100 µm. Custom end caps and core materials are also available upon request. Contact us with your requirements for a tailored solution.
