Fablab Rwanda builds COVID-19 spray door frame

“It sprays a 360-degree mist of foggy hydrogen peroxide (H2O2) in an automated response to human movement. The sanitizing tunnel has a total of 7 mist nozzles, 3 at each side and 1 from the ceiling. To reach the nozzle, the spray flows from a fiber tank, pressured by an electric pump. With a 90 percent disinfection effect, the machine has a sterilization capacity of 1,000 people per day.”
