Anping County Boli Hardware Wiremesh Products Factory is proud to present our Sintered Stainless Steel Filter Cartridge for Chemical Processing — 304 grade, 1μm filtration, rated for 300°C. As a dedicated manufacturer with over two decades of experience (since 1998), we specialize in producing high-performance filtration solutions that meet the demanding requirements of the chemical industry. Our sintered stainless steel filter cartridges are engineered to provide exceptional durability, precise particle retention, and resistance to high temperatures and corrosive environments. With an annual export value of US$5–10 million and serving global markets across North America, South America, Europe, Asia, Africa, and Oceania, we ensure every cartridge delivers consistent quality and reliable performance. Whether you need to remove particulates from aggressive chemicals, polymer melts, or high-temperature gas streams, this filter cartridge is a robust choice.
Key Features & Technical Specifications
- Material: Made from premium SS304 stainless steel powder, sintered into a rigid porous structure for excellent mechanical strength and corrosion resistance.
- Filtration Precision: 1 micron (1μm) absolute rating ensures reliable removal of fine particles, suitable for critical chemical processes.
- High Temperature Resistance: Capable of continuous operation up to 300°C (572°F), ideal for hot gas filtration, polymer filtration, and steam applications.
- Chemical Compatibility: Resistant to a wide range of acids, alkalis, and organic solvents (except strong chlorides and certain reducing acids — consult our technical team for specific media).
- Reusable & Cleanable: The sintered metal matrix can be cleaned via backwashing, ultrasonic cleaning, or chemical cleaning, offering long service life.
- Customizable Dimensions: Available in standard lengths (10", 20", 30", 40") and diameters (2.5", 4.5", etc.), with custom sizes upon request.
- Connection Options: Various end cap configurations: flat gasket, 2" tri-clamp, 1" NPT, flanged, or threaded — adaptable to your housing.

Frequently Asked Questions (FAQ)
-
Q: Can this filter cartridge be used for polymer filtration?
A: Yes, the 1μm rating and 300°C temperature resistance make it suitable for many polymer melt filtration applications. However, we recommend confirming the specific polymer type and viscosity with our technical team. -
Q: How do I clean the cartridge?
A: The cartridge can be cleaned by backwashing with a compatible solvent, ultrasonic cleaning, or thermal treatment (e.g., burning off organic residues). Avoid using strong acids that may attack SS304. -
Q: What is the expected lifespan?
A: Lifespan depends on the operating conditions (temperature, pressure, contamination level). With proper cleaning, the cartridge can last several years. We provide a typical service life estimate based on your application parameters. -
Q: Is the cartridge certified for food-grade or pharmaceutical use?
A: Our SS304 sintered cartridges meet general industrial standards. For specific food or pharmaceutical compliance, please contact us with your requirements so we can recommend appropriate materials and certifications. -
Q: Can you provide custom lengths or diameters?
A: Yes, we offer custom dimensions. Please provide your housing dimensions and desired filtration area, and we will manufacture accordingly. -
Q: What is the maximum pressure drop allowed?
A: The maximum differential pressure is 3.0 MPa at room temperature. At elevated temperatures, the allowable pressure drop decreases; consult our engineering team for guidance. -
Q: Do you offer samples before bulk order?
A: Yes, we can provide samples for evaluation. Please contact our sales team to discuss sample size and shipping terms. -
Q: How is the cartridge sealed in the housing?
A: We offer multiple end cap options: flat gasket, tri-clamp, NPT thread, flanged, etc. The sealing method depends on the housing design. We can advise the best choice for your system.
