Welcome to Anping County Boli Hardware Wiremesh Products Factory — a trusted manufacturer since 1998, specializing in precision filtration solutions. Our Metal Powder Sintered Filter for Pharmaceutical Filtration 316L 0.5 Micron Sanitary Design is engineered to meet the rigorous demands of the pharmaceutical industry, where purity, reliability, and compliance are non-negotiable. With an annual export value of US$5–10 million and a global presence spanning North America, Europe, Asia, and beyond, we deliver high-performance filters that ensure consistent product quality and process efficiency. This filter combines advanced sintering technology with a sanitary design, making it an ideal choice for sterile applications, such as final filtration of injectables, biopharmaceuticals, and high-purity solvents.
Key Features and Benefits
- 0.5 Micron Precision Filtration: Achieves high retention of particles, bacteria, and contaminants, ensuring product purity and compliance with pharmacopoeia standards.
- 316L Stainless Steel Construction: Offers excellent corrosion resistance, withstands aggressive cleaning agents, and is compatible with steam sterilization (SIP) and autoclaving.
- Sanitary Design: Smooth, crevice-free surfaces and tri-clamp connections facilitate easy cleaning, prevent bacterial growth, and meet GMP and cGMP requirements.
- High Mechanical Strength: Sintered metal powder structure provides robust integrity, capable of handling high differential pressures and backwashing for extended service life.
- Thermal Stability: Operates effectively at temperatures up to 600°C (with suitable seals), making it suitable for hot filtration and sterilization cycles.
- Reusable and Cost-Effective: Can be cleaned and regenerated multiple times, reducing replacement costs and waste compared to disposable filters.

Frequently Asked Questions
Q1: Can this filter be steam-sterilized in place (SIP)?
Yes, the 316L construction and sanitary design allow repeated steam sterilization at temperatures up to 150°C (with appropriate seals).
Q2: What is the typical lifespan of the filter?
Lifespan depends on operating conditions and cleaning frequency. With proper backwashing and chemical cleaning, the element can last 1–3 years or more.
Q3: Is the filter compatible with organic solvents like ethanol or acetone?
Yes, 316L stainless steel is highly resistant to most organic solvents; however, seal compatibility should be verified (e.g., use PTFE or Viton seals).
Q4: What is the maximum differential pressure the element can withstand?
Typically, the maximum differential pressure is 30 bar for standard elements; higher values are available upon request.
Q5: Can you provide a custom size or connection?
Absolutely. We offer custom lengths, diameters, and connection types (tri-clamp, flange, threaded) to fit your housing.
Q6: What is the recommended cleaning method?
Ultrasonic cleaning, backwashing with clean water or solvent, and chemical cleaning (e.g., with nitric acid or caustic solution) are effective. Steam sterilization also helps.
Q7: Do you provide a certificate of compliance or material test report?
Yes, we can provide material certificates (3.1) and other documentation upon request.
Q8: Is the filter suitable for high-viscosity fluids?
For high-viscosity fluids, we recommend a larger surface area or pre-filtration to avoid excessive pressure drop; consult our engineers for a customized solution.
