3M rated airflow indicator to be used with the Powerflow and the Breathe Easy powered air purifying respirators only. Level marks have been printed on the tube – markings differ depending on which system is in use – to allow one to keep an eye on the respiratory protection quality. If the ball indicator falls below 4CFM (4 ft.3/min), it means the filter has reached its saturation limit or there may be a malfunction in progress. Sold individually.
