As a manufacturer with over 25 years of expertise in metal filtration solutions, Anping County Boli Hardware Wiremesh Products Factory (established 1998) proudly presents our Sintered Metal Powder Filter Element designed specifically for pharmaceutical liquid filtration. This 10 micron 316L stainless steel filter cartridge combines high dirt-holding capacity with exceptional chemical resistance, ensuring consistent purity in critical drug manufacturing processes. Our factory, located in Hengshui, Hebei, China, exports to major markets worldwide with annual export value exceeding US$5 million, and we are committed to delivering reliable filtration components that meet the stringent demands of the pharmaceutical industry.
The filter element is manufactured from high-quality 316L metal powder through a controlled sintering process, creating a rigid, porous structure with uniform pore distribution. The 10 micron rating provides effective removal of particulate contaminants while maintaining high flow rates, making it ideal for applications such as sterile filtration, polishing, and catalyst recovery in pharmaceutical liquid processing. Below are the key technical specifications and features:

| Surface Finish | Electropolished, acid washed, or as sintered |
Key Features & Benefits
- High porosity & uniform pore structure: The sintering process creates consistent pore distribution, ensuring reliable filtration efficiency and negligible media migration.
- Excellent chemical compatibility: 316L stainless steel resists corrosion from a wide range of pharmaceutical chemicals, solvents, and cleaning agents.
- Thermal stability: Suitable for high-temperature applications such as hot water sterilization (CIP/SIP) and steam sterilization up to 200°C.
- High mechanical strength: The rigid sintered matrix withstands high differential pressure without deformation, extending service life.
- Cleanability & reusability: Can be backwashed or chemically cleaned multiple times, reducing replacement costs and waste.
- Low pressure drop: Optimized porosity ensures high flow rates with minimal energy consumption.
- Compliance with pharmaceutical standards: Manufactured in a controlled environment; materials are traceable and suitable for cGMP applications.
- Customizable dimensions: Available in various lengths, diameters, and end cap configurations to fit existing housings.
Typical Applications in Pharmaceutical Liquid Filtration
- Active pharmaceutical ingredient (API) purification
- Final sterile filtration of injectables and ophthalmic solutions
- Filtration of solvents, buffers, and intermediates
- Catalyst recovery in chemical synthesis
- Pre-filtration before membrane filters to extend membrane life
- Filtration of cleaning solutions (CIP) and rinse water

Frequently Asked Questions
-
Q: What is the difference between nominal and absolute filtration rating for this filter element?
A: The nominal 10 micron rating indicates that the filter retains a majority of particles ≥10 microns under standard test conditions. For absolute rating (typically 25 micron), please contact our sales team for specific bubble point data. -
Q: Can this filter element be used for steam sterilization?
A: Yes, the 316L sintered metal filter can withstand repeated steam sterilization cycles up to 200°C (392°F). Ensure proper support and avoid rapid temperature changes to prevent thermal shock. -
Q: What end cap configurations are available?
A: Standard options include DOE (Double Open End), 222 (flat gasket), 226 (flat gasket with O-ring), and 215 (with O-ring). Custom configurations can be made to match your housing. -
Q: How do I clean and reuse the filter element?
A: Backwashing with clean water or compatible solvent, followed by ultrasonic cleaning, is effective. Chemical cleaning with mild acids or alkalis is also possible. Avoid using abrasive tools that may damage the porous structure. -
Q: What is the typical pressure drop across a 10 micron 316L filter element at a given flow rate?
A: Pressure drop depends on fluid viscosity, temperature, and element dimensions. For water at 20°C, a 10″ element with 60mm OD typically has ~0.2 bar drop at 10 L/min. Please request a detailed calculation for your specific conditions. -
Q: Do you provide material certification for the 316L stainless steel?
A: Yes, we can provide a mill test certificate (MTC) for the raw material and a certificate of compliance (CoC) for the finished filter element upon request. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is typically 10 pieces. For custom dimensions, MOQ may be higher depending on complexity. Please contact us for a quote. -
Q: Can the filter element be used for high-viscosity liquids like oils or syrups?
A: Yes, but the flow rate will be reduced compared to water. We recommend selecting a larger filtration area or a coarser pre-filter to optimize performance. Our team can help with sizing.
Contact us today for a quotation or technical consultation. We ship from Tianjin, Qingdao, Shanghai, and Foshan ports, with lead times typically 15-25 working days. Let us support your pharmaceutical filtration needs with reliable, high-quality sintered metal powder filter elements.
