Optrel e640 PAPR: welding helmet shell with hard hat for the e3000X system
The professional Optrel e640 helmet shell in the PAPR version with an integrated hard hat is a specialist solution for welders in the most demanding industries, such as construction and shipbuilding. It is designed as a key component of the Optrel system and lets you build or upgrade your personal protection set economically. Combine it with the e640 series auto-darkening filter (ADF) you already own and the e3000X air supply system to create a set that protects your head against impacts, protects your eyes and gives certified respiratory protection to class TH3. The ADF and the e3000X blower unit are not included, you buy them separately.

Technology details
Integrated head protection (hard hat)
This shell combines a professional welding helmet with a certified hard hat in one tool. You no longer need awkward adapters or two separate pieces of protective equipment, which matters on construction sites, in shipyards and in production plants where head protection against impacts is mandatory. The design gives good balance and comfort even during long shifts. This integrated solution means full compliance with health and safety rules, higher productivity and comfortable work.
Modular design and compatibility
The product is supplied as a complete shell with an air distribution system, but without an auto-darkening filter (ADF). This modularity is central to the Optrel approach and saves a lot of money over the life of the equipment. If the shell is mechanically damaged, you do not need to buy a new, expensive ADF filter: you only replace the shell itself. The shell is precisely matched to e640 series filters, which ensures a tight seal and a stable fit. It is a smart choice that lowers the long-term cost of owning and servicing your equipment.
Material resistant to high temperature and impact
The helmet body is made of advanced, high-quality plastic with increased resistance to high temperatures and radiant heat. The material is also highly resistant to impact and spatter, which protects both your face and the sensitive electronics of the ADF filter. The robust design gives reliability and safety in the toughest industrial conditions, from welding heavy structures to work in confined spaces. With this shell you get durability and reliability from your most important piece of protective equipment.
Optimised air distribution system
The shell is designed as an integral part of the e3000X system. It has a built-in air duct (airduct) and a dedicated face seal, which together form an advanced air distribution system. Unlike simple designs, it directs the flow of clean air in a controlled way, spreading it evenly over your face and adding a cooling effect on the forehead. Precisely designed channels prevent unpleasant direct draughts onto the eyes, which could cause irritation and fatigue. The result is comfort that lets you stay focused and productive for the whole shift.
TH3 respiratory protection
Combining this shell with the Optrel e3000X air supply system gives a certified respiratory protection set of the highest class TH3 (according to EN 12941). This means the system filters 99.8% of harmful particles, fumes and aerosols produced during welding. The face seal together with constant positive pressure inside the helmet separates your breathing zone from the contaminated surroundings. It is a basic investment in your own health that protects you from irreversible lung disease and lets you work safely for many years.
