Allegro 9935-BHTX81V Papr Welding Helmet 81VX Auto-dark

Product Description

The ALLEGRO 9935-BHTX81V is a powered air-purifying respirator (PAPR) welding helmet designed for welders and fabricators who need integrated respiratory protection alongside optical protection. The helmet ships with the 81VX auto-darkening filter, which mounts in a flip-up configuration over the face shield, allowing the wearer to switch between the auto-dark lens and the full face shield without removing the headgear. The nylon headgear shell is sized universally and is engineered for compatibility with the EZ Air PAPR system. At 10 pounds, this is a full-assembly unit intended for professional weld environments where both arc flash and airborne contaminants must be controlled simultaneously.

This helmet is suited for professional welding applications in industrial, manufacturing, and fabrication settings where PAPR respiratory protection is required alongside auto-darkening optical coverage. The flip-up lens design is practical in environments where the welder alternates between welding and grinding or inspection tasks, eliminating the need to remove the helmet between operations. The universal fit accommodates a range of head sizes, making it a practical option for shared-use toolroom environments or multi-tech crews. It is compatible with the EZ Air PAPR series and includes the 81VX auto-darkening filter as part of the standard package.

Installation Notes

Installation and fitting should be performed by a qualified safety professional or industrial hygienist familiar with PAPR systems and welding PPE requirements. Before connecting the helmet to any PAPR blower unit, ensure the blower is powered off and all hose connections are inspected for damage. Verify the auto-darkening filter is properly seated in the flip-up lens housing and functioning before beginning any welding operation. Refer to applicable ANSI Z87.1 and OSHA 29 CFR 1910.252 standards for welding eye and face protection requirements.
