For reliable, comfortable airflow when using 3M™ Adflo™ Powered Air Respirator, get 3M™ Adflo™ Breathing Tube, 834009. This breathing tube may be required when using the respirator in a gas filter configuration, alongside 3M™ Adflo™ Heavy-Duty Battery (837631). Our breathing tube features a silencer and a an integrated QRS (Quick Release Swivel) connection that enables fast and easy one-handed connection and release. The current program of welding helmets and face shields from 3M feature the QRS connection, but for the older 3M™ Speedglas™ Welding Helmet Series 9000 and 3M™ Protective Visors you need to add an adapter (533506).
