3MH70-0716-0685-2 - 3M Speedglas Self-Adjusting QRS Breathing Tube for 9100 FX Air

Reliable Air Delivery for Speedglas PAPR Systems

The 3M Speedglas Breathing Tube 834016 is a critical component for maintaining the safety and integrity of your Adflo Powered Air Purifying Respirator (PAPR) system. Designed specifically for use with the Speedglas 9100 FX Air and 9100 MP welding helmets, this breathing tube ensures a secure and consistent channel for filtered air to reach the user's breathing zone. Maintaining a leak-free connection between the blower unit and the headtop is essential for achieving the assigned protection factor (APF) required in hazardous industrial welding environments.

Innovative Self-Adjusting Design

One of the primary engineering features of the 834016 model is its self-adjusting, helical construction. Unlike fixed-length rubber tubes that can create dangerous loops capable of snagging on machinery or workpieces, this tube automatically expands and retracts based on the distance between the welder's head and the belt-mounted unit. This dynamic length adjustment significantly reduces the profile of the welder, minimizing trip hazards and entanglement risks in tight or cluttered workspaces. The tube is constructed from durable polyurethane, offering a balance of flexibility and resistance to general wear and tear found in fabrication shops.

Quick Release Swivel (QRS) Connection

Efficiency in donning and doffing safety gear is paramount for productivity. This breathing tube features 3M's Quick Release Swivel (QRS) connection mechanism. The QRS system allows for rapid, one-handed connection and disconnection of the hose from the air source. This is particularly beneficial during breaks or when switching between different tasks where the helmet might need to be removed while keeping the PAPR blower belt on. The swivel function also prevents the tube from kinking or twisting, ensuring uninterrupted airflow regardless of the welder's orientation or movement.

Maintenance and Safety Compliance

Regular inspection of the breathing tube is a mandatory safety protocol. While the 834016 is built for durability, it should be inspected daily for punctures, cracks, or deformation. Any breach in the tube compromises the positive pressure seal and can allow contaminants to enter the breathing zone. This genuine 3M replacement part ensures that your equipment remains compliant with safety standards and functions as intended within the complete Speedglas respiratory system.
