Material Excellence: Constructed from food-grade 304/316L stainless steel with surface polishing to Ra≤0.8μm, meeting GMP and FDA standards. The non-toxic, odorless material resists acid, alkali, and organic solvent erosion, ensuring zero secondary contamination.
Sterilization Performance: Equipped with imported or high-quality domestic sterile filter elements (PTFE, PP, hydrophilic polyethersulfone) with filtration precision of 0.22μm/0.45μm. Achieves sterilization rates up to 99.999%, effectively intercepting bacteria, spores, microorganisms, and solid particles.
Structural Integrity: Integrally formed by precision welding with no dead corners in internal structure, preventing medium retention and bacterial breeding. Withstands working pressures up to 1.0-1.6MPa and temperatures from -10℃ to 120℃.
Maintenance Efficiency: Flange-type or clamp-type connection design allows quick disassembly and replacement of filter elements, saving maintenance time and labor costs.
ESP Filter Innovation: The company's proprietary ESP Filter with internal pleated cartridge delivers 3-5 times larger filtration area than conventional designs, with pressure drop ≤70Pa for exceptional energy-saving performance. This technology complies with ISO, FDA, and GMP standards, making it ideal for pharmaceutical liquid filtration and compressed air sterilization.
