Absolutely yes. Nursing stations are notorious hives for employee-employee aerosolized infection, such as during rounds or meetings where multiple employees gather in tight groups. Even though employees all wear masks, I demonstrated that 1 in 10 infectious aerosol particles leaks through a mask [view here in Part 3]. For example, with one employee who is infected (relatively speaking), if there are just two employees in the station the chances of the other getting infected is 1 in 100 such meetings. However, if there are five employees in the station, the chances that one will get infected is 1 in 20 such meetings. So a crosswind unit with a wider beam (without air concentrator but with a baffle) suspended from the ceiling running at 3 m/s during a meeting will be very effective in further reducing infection probability in these settings. If all employees in the meeting feel a crosswind breeze in their faces, it will work very well. See also bathroom infections in Question Q12.
