3M™ Versaflo™ TR-973 air flow indicator may be used to indicate air flow levels of the TR-600 and TR-800 series PAPRs when used with tight fitting face pieces. The TR-973 is designed to enable testing at various elevations and temperatures within the operational range of the PAPR system.
Ensure your 3M™ Powered Air Respirator System is exceeding its minimum flow rate with 3M™Airflow Indicators. Our airflow indicators provide a simple and reliable way to test the airflow of your respirator system. The airflow of the unit must be checked before every use. If the air flow level is below the minimum flow rate, the respirator system should not be used until further examination and repair where necessary.
