Allegro 9935-BHTX54V Papr Welding Helmet 54V Auto-dark

Product Description

The ALLEGRO 9935-BHTX54V is a powered air-purifying respirator (PAPR) welding helmet designed for welders who need both respiratory protection and arc flash coverage in a single integrated unit. The helmet ships with a 54V auto-darkening filter housed behind a flip-up welding lens over a full face shield. The nylon headgear is sized universally to fit a wide range of head sizes. This unit is built for use within the ALLEGRO EZ Air PAPR system, making it a direct accessory or replacement component for technicians already operating that platform. A licensed welder or qualified safety technician handles the setup and fitting.

The 9935-BHTX54V is suited for industrial and commercial welding environments where respiratory hazards and optical arc exposure occur simultaneously. The flip-up window design allows the face shield to remain in place while the welding lens is raised between passes, reducing the need to remove the helmet entirely. It is appropriate for use in fabrication shops, maintenance facilities, shipyards, and heavy manufacturing settings where PAPR-integrated head protection is required. Compatibility is specific to the EZ Air PAPR system platform from ALLEGRO.
