Honeywell PA031L PAPR Breathing Tube - Large

The Honeywell PA031L is the large (long) breathing tube designed for use with the PA700-series belt-worn PAPR systems. The breathing tube routes filtered air from the blower motor at the waist to the face-piece, and in that role it endures constant flexing, UV exposure, and the mechanical stress of regular donning and doffing. Replacing a cracked or degraded breathing tube is one of the most frequently overlooked steps in PAPR maintenance programs, yet a compromised tube can allow unfiltered air to bypass the respirator entirely.

The PA031L is specifically the large-size variant, suited for taller workers or configurations requiring a longer tube run between the belt unit and the headtop. The 'L' designation matters when ordering — the shorter PA031S fits smaller workers and certain headtop configurations. Honeywell recommends annual breathing tube replacement as a minimum, with more frequent replacement if the tube shows any visible cracking, discoloration, or deformation at the connection fittings.

Facilities running Honeywell North PA700 or PA701 series PAPR systems should stock spare breathing tubes as part of their standard PPE inventory. Tube failure is a foreseeable event with a simple fix — a bag of spare PA031L tubes prevents production downtime when a tube fails mid-shift. The tube connects to the blower outlet and the face-piece adapter using the standard Honeywell North bayonet fittings, requiring no tools for replacement in the field.

Key Features

An air-purifying respirator filters air, it does not supply any. Under 29 CFR 1910.134 no air-purifying respirator may be worn in an atmosphere that is IDLH or oxygen-deficient (below 19.5% oxygen). Those conditions require a supplied-air respirator or an SCBA, and no filter or cartridge rating changes that.

• Large (long) size — for tall workers or extended blower-to-headtop distance
• Compatible with Honeywell North PA700 and PA701 series PAPR blowers
• Standard Honeywell North bayonet fittings — tool-free field replacement
• Flexible corrugated construction — withstands constant flexion without kinking
• Low breathing resistance — smooth internal bore for unrestricted airflow
• Replacement part — sold individually for maintenance programs
