The medical vacuum system provides a sterile negative pressure source for surgical suction and sterilization equipment. The dry rotary vane pump emits no oil vapor and achieves microbial inactivation through HEPA/TiO ₂ filters, in compliance with YY/T0799 standards. In freeze-drying pharmaceuticals, the composite pump maintains a vacuum environment of -50 ℃ to preserve the activity of biological agents; The intelligent operation and maintenance system predicts bearing failures to ensure reliable 24/7 operation of ICU equipment.
