The Parweld XR940A is a powered air purifying respirator (PAPR) suitable for use with welding and grinding applications.  Meeting HSE guidelines for protection against welding fume, these air fed systems are supplied complete and ready to go.  A P3 particulate main filter filters atmospheric air to deliver clean air to the wearer.  A carbon activated pre-filter eliminates odours and a metal spark arrestor preserves filters.

The Parweld XR940A system has been tested and has been certified of TH3 classification inward leakage protection of less than 0.2%.

  • Welding of Stainless Steel, MIG and TIG process
  • Welding of Steel by MMA, MIG or TIG
  • Welding of Zinc coated Steel by MIG or TIG



Blower unit protects the user against concentrated fumes and gas emissions generated in the welding and cutting processes.  Clean air supplied gives the user a comfortable level of clean air to breathe.  Standard air flow rate is 170 l/min and electronics ensure consistent supply of air through the blower unit.  The supplied battery can last over 11 hours in the standard setting and 9 hours in the higher 220 l/min setting.  Times supplied rely upon a fully charged battery and unimpaired filters.

The blower unit is worn on a comfortable belt and an over shoulder harness is also supplied to increase wearer comfort.

TBWS Verdict:  The blower unit and belt stand out as really nice quality on these Parweld units.  The materials used to make the blower are a hard, robust plastic unlike some other PAPR systems out there.  Spares are well priced and the helmet has a very large viewing area, great for any welding process.  The addition of an included harness is a nice touch for added comfort, to stop the belt from falling.
