EVADE system (Externally Vented Aerosol and Droplet Evacuation System)
View Patent ↗The EVADE (Externally Vented Aerosol and Droplet Evacuation) system is designed to treat collected aerosols with ultraviolet radiation and exposure to ozone gas to prevent the spread of COVID or other infectious pathogens. The system uses an externally vented central vacuum system which produces up to 280 CFM of vacuum flow to facilitate collection of potentially contaminated oral aerosols and droplets generated by instrumentation of any type within the medical, dental or any other field which generates said aerosols. The aerosols are collected within a mirrored chamber, reflecting UVC light in all directions and exposing the aerosols to ozone before moving through HEPA particle filtration and out of the environment through the exhaust of a central vacuum system.
