The 3M™ Versaflo™ Breathing Tube BT-20L is a large lightweight breathing tube that is easy to wipe down. A breathing tube connecting the air source with the headtop is required to ensure that clean air reaches the headtop reliably and with unrestricted airflow. The breathing tubes offered are compatible with all 3M™ Versaflo™ Headtops and Air Delivery Units.
Some non-Versaflo PAPR and Supplied Air Valve configurations require adapters to work with the BT-20L Breathing Tube. Please consult your 3M™ Product Matrix for details.
