AP-BT2-FR - Walter FR Extended Reach PAPR Hose

Premium Protection and Mobility for PAPR Systems

The Walter AP-BT2-FR Extra Long Breathing Tube is a critical accessory designed to enhance the functionality and safety of Walter Powered Air Purifying Respirator (PAPR) systems. In industrial welding environments, the integrity of the breathing apparatus is paramount. Standard breathing tubes can be susceptible to damage from molten spatter, sparks, and radiant heat, potentially compromising the clean air supply to the operator. This specialized model addresses those risks directly by incorporating a flame-retardant (FR) cover that shields the underlying hose material from the harsh realities of heavy fabrication and welding.

Beyond its protective qualities, the AP-BT2-FR is engineered for ergonomics. The "Extra Long" designation indicates that this tube provides a greater range of motion compared to standard-length hoses. For industrial professionals who frequently work in large fixtures, perform out-of-position welding, or require significant maneuverability around their workpiece, the added length is a substantial operational advantage. It reduces the likelihood of the hose snagging or pulling tightly against the helmet, which can cause neck strain and break the face seal, compromising the assigned protection factor (APF) of the respirator unit.

Compatibility and durability are core to the design. The connections are precision-molded to fit securely into Walter PAPR blower units and headtops, ensuring an airtight seal that prevents the ingress of particulate matter and fumes. The hose itself is constructed to remain flexible even when covered, preventing kinks that could restrict airflow. For facility managers and safety officers, investing in FR-rated breathing tubes like the AP-BT2-FR reduces long-term replacement costs by extending the lifespan of the equipment in aggressive welding environments.

Key Technical Benefits

• Flame Retardancy: Essential for Flux-Cored Arc Welding (FCAW) and overhead applications where spatter is prevalent.


• Extended Reach: Facilitates movement in confined spaces or around large assemblies without restricting the welder's head movement.


• System Integrity: Maintains the NIOSH-approved configuration of the Walter PAPR system when used as a direct replacement.
