Stainless Steel Micro-pore Microporous Multi-cartridge High Precision Sterile Micron Filter
 
Overview The Stainless Steel Micro-pore Microporous Multi-cartridge High Precision Sterile Micron Filter is a core precision filtration equipment for high-cleanliness production environments such as biopharmaceutical aseptic fluid processing, medical aesthetic preparation refining, high-end food and beverage terminal filtration, drinking water purification, and daily chemical fluid sterilization and impurity removal. It is specifically designed for quick-connect piping connections in Class A clean areas, online aseptic filtration, CIP/SIP in-situ cleaning and sterilization, and long-cycle continuous production. The Micro-pore Filter is made entirely of AISI 304/316L low-carbon pharmaceutical-grade stainless steel, precision molded in one piece. Its core features include a high-precision pleated microporous filter element, a quick-connect clamp locking structure, a sanitary-grade dead-angle-free flow channel, an FDA-certified aseptic sealing system, and a full-flow channel ultra-mirror electrolytic polishing. The straight-through cylinder eliminates stagnation, blind spots, and harmful substance release, achieving high-precision solid-liquid separation, sterilization, particle removal, and colloid removal from 0.1~100μm. It is a core upgrade equipment for high-cleanliness fluid production lines to achieve stable filtration, aseptic compliance, and efficient operation and maintenance.Multi-cartridge Filter

The Stainless Steel Micro-pore Microporous Multi-cartridge High Precision Sterile Micron Filter represents a comprehensive upgrade in filtration accuracy, aseptic protection, ease of installation and disassembly, and cleanability.
Ordinary pipeline filters: low accuracy, only capable of coarse filtration, unable to remove bacteria or particles, lacking sanitary design;
Non-standard welded filters: numerous welds, many dead angles, prone to material accumulation and bacterial contamination, not suitable for quick installation and disassembly;
Non-quick-connect structure: flange connections are cumbersome to install and disassemble, filter element replacement is time-consuming, unsuitable for batch production;
Ordinary material filters: not resistant to acids and alkalis, not resistant to high-temperature sterilization, prone to corrosion and leaching, not compliant with GMP/FDA;
Non-compliant design: no polishing standards, no sealing certification, untraceable, unable to pass cleanroom audits.
 
Working Principle
TheStainless Steel Micro-pore Microporous Multi-cartridge High Precision Sterile Micron Filter consists of six main modules: quick-connect cylinder, clamp locking, inlet and outlet quick-connect interfaces, microporous pleated filter element, filter element socket, sealing components, and support feet/lifting rings. During operation, the fluid to be filtered enters the cylinder through the side/top inlet and, under pressure, passes evenly through the multi-layered pleated microporous filter element. Through a triple action of deep interception, surface sieving, and adsorption capture, particles, impurities, colloids, and microorganisms in the fluid are removed. The clean fluid flows out from the bottom inlet, while contaminants are trapped on the surface and inside of the filter element. For maintenance during shutdown, the quick-release clamps can be released with a single button, the top end cap can be quickly opened, and the filter element can be directly removed for replacement or cleaning. The entire flow path is smooth and straight, enabling CIP/SIP online cleaning and sterilization, with no dead corners, no residue, and a completely sealed and sterile process.
