Disinfection Room VOC Control at Sun Yat-sen Hospital
Third Affiliated Hospital of Sun Yat-sen University
Nurses and technicians at the Third Affiliated Hospital of Sun Yat-sen University spend full shifts in the endoscopy disinfection room, breathing air thick with chemical fumes. The cleaning agents used to sterilise scopes between procedures release heavy concentrations of VOCs. It smelled bad. It felt worse. And long-term exposure posed real health risks the hospital couldn't ignore.
RHT identified the gastroscope washing station as the primary VOC source and installed a two-unit system: a duct-mount RH-220 to clean the ventilation air and a ceiling-mount RH-490C to treat the room directly. The results were immediate — peak TVOC removal hit 82%, with an average sustained rate of 73%. The air in the disinfection room now meets occupational safety standards. Staff breathe easier, literally.
