The spray‑disinfection air shower adopts high‑pressure silent atomization technology. Its core working principle: after pressurization by a high‑pressure pump, liquid disinfectant is shattered into micron‑scale ultra‑fine droplets through precision micro‑orifice nozzles, which is different from conventional sprinkling or spraying modes. The qualified industry‑standard atomized droplet size ranges from 10 ~ 20 μm. Droplets within this size range feature good suspension performance and uniform coverage without water accumulation or residual liquid. They can fully contact microorganisms for sterilization while avoiding liquid residue on human bodies, materials and equipment surfaces.
Core bactericidal mechanism: Ultra‑fine droplets penetrate clothing fibers and gaps of materials to cover blind spots unreachable by conventional UV disinfection. They denature and inactivate proteins of bacteria and viruses, achieving efficient inactivation of Escherichia coli, Staphylococcus aureus, moulds, yeasts and various environmental pathogenic bacteria, with an overall bactericidal rate ≥ 99.9 %. Compared with UV disinfection which suffers plenty of dead corners and ozone disinfection with strong irritation, atomized disinfection delivers safer and more thorough sterilization with zero dead zones.
The atomization system is equipped with multiple safety designs. A dedicated explosion‑proof atomizing pump supports alcohol‑based disinfectants to eliminate potential safety hazards. Real‑time liquid‑level monitoring triggers automatic shutdown and alarm under water‑shortage conditions to prevent equipment damage caused by dry running. Adjustable atomization concentration allows spray volume tuning according to clean‑room sterility grades to avoid human irritation from excessive concentration. A post‑disinfection exhaust system rapidly evacuates residual mist after disinfection to guarantee safe personnel access.
Compatible disinfectants include industry‑compliant options such as 75 % medical‑grade alcohol, hypochlorous‑acid disinfectant and slightly‑acidic electrolyzed water. Strongly corrosive or high‑residue disinfectants are strictly prohibited. Proper disinfectant selection preserves the stainless‑steel chamber and extends service life while maintaining satisfactory sterilization performance. Reliable atomization technology constitutes the fundamental guarantee for efficient, safe and long‑term disinfection performance of the equipment.
