The Manikin Coughing System (Cough Simulator) is a high-precision experimental device designed to operate with a thermal manikin or a manikin head, or as an independent unit. It is used to simulate realistic human coughing conditions. By adjusting cough airflow rate, initial jet velocity, pressure, and duration, you can study aerosol particle dispersion and transmission under indoor or confined-space airflow conditions. The system provides reliable experimental data for indoor air quality studies, pollutant exposure assessment, and airborne infectious disease research.
