3M Engine Driven Airflow Indicators are designed to test the minimum airflow rate of 3M Engine Driven Respirators.
Check if your 3M Adflo Motor Powered Breathing System reaches the minimum airflow rate with the 3M Airflow Indicator. Our airflow indicators provide a simple and reliable way to test the airflow of your respiratory system. Respiratory system airflow should be checked before each use. If the airflow level falls below the minimum flow rate, the breathing system should not be used until further investigation and should be repaired if necessary.
