Verified through 4.0 MPa testing, the patented interface design guarantees secure sealing and easy maintenance. The ACF Series employs precision die-casting technology and patented drainage structures, making it ideal for semiconductors, laser cutting, medical equipment, and food processing.
Yuanmei ESP Filter with Internal Pleated Filter Cartridge: This flagship product delivers 99.9% particle interception rate with 3-5 times larger filtration area than conventional filters. Constructed from 304/316L stainless steel with PP/PTFE/stainless steel pleated cartridges, it achieves filtration precision from 0.1-60μm. The optimized design maintains pressure drop ≤70Pa, reducing system energy consumption by 15%-25%. The filter body withstands temperatures up to 200℃, while PTFE cartridges operate up to 250℃. Compliant with ISO 9001/FDA/GMP standards, the ESP Filter features detachable cartridges for quick replacement without pipeline shutdown, extending service life 1.5-2 times longer than ordinary cartridges.
Yuanmei Stainless Steel Sterile Filter: Engineered for pharmaceutical, food & beverage, and biotech industries, this filter uses food-grade 304/316L stainless steel with surface polished to Ra≤0.8μm, meeting GMP and FDA standards. Equipped with imported or high-quality domestic sterile filter elements (PTFE, PP, hydrophilic polyethersulfone) with filtration precision of 0.22μm/0.45μm, it achieves a sterilization rate of up to 99.999%. The integrally welded filter body eliminates dead corners, withstands working pressures up to 1.0-1.6MPa, and operates in temperatures from -10℃ to 120℃.
