Publication number: 20230288085Abstract: Technologies are described for providing safe and clean air and to prevent interchange of fluids or particulates between people in social situations through two or more distinct airflows generated and/or directed by various structures. An air safety system may receive pre-sanitized air and push through a guidance structure to create a low-velocity, clean air safe zone that prevents exchange of fluids and particulates within the zone and a high speed air shield to prevent injection of fluids and particulates from outside into the safe zone. The system may accommodate one or more persons in an open space of over a table/desk. A modular air safety system may generate a similar safe zone and air shield horizontally in a smaller scale for one or more people.Type: ApplicationFiled: November 18, 2020Publication date: September 14, 2023Applicant: ITT Manufacturing Enterprises LLCInventors: A.
