Positive pressure ventilators are portable fan units that can be positioned relative to an opening of a confined space and cause it to be positively pressurized by discharge air velocity. They are principally used by firefighters to mitigate the effects of smoke. The standard provides a method of testing positive pressure ventilators for performance ratings in terms of airflow rate, pressure, air density, and speed of rotation.
