Products Description
Need a durable, chemically compatible filter for high-pressure or high-temperature applications?
Guanjiang's Stainless Steel Filters are filtration devices manufactured from 304/316L stainless steel, utilizing filter elements such as sintered mesh, woven wire mesh, or filter felt to achieve solid-liquid or solid-gas separation. Their core value lies in providing a mechanically stable, chemically compatible, and easily maintainable filtration solution — widely used in applications requiring hygiene, corrosion resistance, or high-temperature capability. With filtration precision from 0.5 to 500μm and operating temperatures up to 500°C, these filters are ideal for chemical, pharmaceutical, and industrial processing.
Key Advantages
Resists various acids, alkalis, solvents, and aqueous media. Surfaces electropolished to Ra≤0.5μm — complies with GMP and FDA standards. No leaching, no contamination.
Withstands pressure fluctuations with maximum working pressures up to 10 MPa. Integrated support and filter layers provide resistance to mechanical shock — suitable for high-pressure pipeline systems.
Filtration ratings from 0.5 to 500μm. Supports online backpulsing, ultrasonic cleaning, and chemical soaking — reusable, significantly reducing consumable costs.
Operates from -196°C to 500°C. Low thermal expansion coefficient — suitable for high-temperature sterilization, hot air conveyance, and melt filtration.
Available in various forms: filter cartridges, filter discs, filter plates, filter tubes. Supports standard connections: clamp, threaded, flange. Custom designs available.

Frequently Asked Questions
Q1: What is the difference between sintered mesh and woven wire mesh filters?
A: Sintered mesh consists of multiple layers diffusion-bonded together — offers higher mechanical strength, precise pore size control, and excellent backflush capability. Woven wire mesh is a single-layer weave — lower pressure drop but less robust. Sintered mesh is preferred for high-pressure, high-temperature, and frequent cleaning applications.
Q2: How do I clean and regenerate the stainless steel filter?
A: The filter supports multiple regeneration methods: Online backpulsing (reverse flow of gas/liquid), Ultrasonic cleaning (in suitable solvent), Chemical soaking (dissolving trapped particles), or Thermal regeneration (burning off organic residues). Proper regeneration extends service life significantly.
Q3: What is the maximum operating pressure?
A: Standard stainless steel filters withstand up to 10 MPa (100 bar / 1450 PSI) depending on configuration. High-pressure versions are available for specialized applications. The integrated support layer prevents filter collapse under pressure differentials.
Q4: Is the filter suitable for food/pharmaceutical applications?
A: Yes. With SS316L construction and electropolished surfaces (Ra≤0.5μm), the filter meets GMP and FDA requirements. No media migration or particle shedding ensures product purity. Full material traceability documentation available.
Q5: What connection types are available?
A: We offer threaded (NPT/BSPT/G threads), universal filter connections (215/220/222/226/flat-seated), and flange connections. Custom connections available upon request. The 226 card-in type is most common for standard filter housings.
