The optimized design maintains pressure drop below 70Pa, reducing energy consumption and extending service life 1.5-2 times beyond standard cartridges. Detachable cartridges enable quick replacement without pipeline shutdown, significantly reducing maintenance labor costs.
Gas-Water Separator Systems
Engineered with advanced centrifugal separation technology, Yuanmei's separators achieve 99.9% liquid separation efficiency, removing water, oil mist, and solid contaminants from compressed air systems. The optimized internal flow channel design minimizes pressure loss while automatic drain valves eliminate manual maintenance requirements. Heavy-duty stainless steel or carbon steel construction withstands high working pressures and temperatures with exceptional corrosion resistance.
Stainless Steel Sterile Filter Line
Manufactured from food-grade 304/316L stainless steel with surface polish to Ra≤0.8μm, these filters meet GMP and FDA standards for pharmaceutical and biotech applications. Equipped with PTFE, PP, or hydrophilic polyethersulfone elements at 0.22μm/0.45μm precision, the filters achieve 99.999% sterilization rates. Precision-welded bodies eliminate dead corners, withstanding 1.0-1.6 MPa working pressures and temperatures from -10°C to 120°C.
