ESAB Savage A40 / A41 Air with EPR-X1 PAPR Parts FAQs

How to identify, check and care for the spare parts of a welding helmet used with a powered air respirator unit.

How do I find the right spare part for my powered respirator helmet?

Start with the helmet and the blower unit, because a powered respirator helmet is a matched system: the helmet, hose, filters and blower are assessed together. Check the labels and markings on the helmet shell, the blower and the filter cover, and use the parts list in your manual.

HSE guidance says replacement parts should ideally come from the original manufacturer so the equipment still performs as intended, and maker manuals say the stated protection only applies with the filters they specify. Compare the old part with the new one, note any version marking, and do not mix in parts from a different system without the maker's confirmation.

Does a powered air helmet need a face fit test?

Generally no. The HSE explains that tight-fitting facepieces, such as masks, rely on a good seal with the face and need a face fit test. Loose-fitting facepieces, such as hoods and helmets, rely on being given enough clean air to keep contaminants out, and HSE guidance lists fit testing as not required for powered hoods and helmets.

That does not mean fit does not matter. The helmet still needs to be the right size and adjusted correctly, with the headband set so the visor and seal sit as the maker intends. Follow the maker's instructions for adjusting your helmet.

What do the protection class markings on a powered helmet mean?

Powered respirators with a helmet or hood are tested against a European standard, which sets minimum requirements and tests for the complete device, including leakage, breathing hoses and warning facilities. Devices are given classes TH1, TH2 and TH3, and the HSE lists their protection factors as 10, 20 and 40 respectively.

The class applies to the whole assembly as tested, not to a part on its own. Fitting a different filter, hose or helmet part could change that, so use the spares the maker lists for your system. The marking on your helmet and your manual state the class. Newer editions of the standard exist, so the marking on newer equipment may differ.

Who should examine and maintain the powered unit, and how often?

HSE guidance says reusable respiratory protective equipment needs thorough examination and, where appropriate, testing at suitable intervals, by a competent person following the maker's instructions. The HSE suggests this is at least monthly, or every three months if the equipment is used only occasionally, and that records are kept for at least five years.

Checks include changing filters, cleaning, checking straps, and checking the battery charge and airflow of powered units. Daily user checks are in addition to this, not a substitute. Your risk assessment and your manual decide what applies to your workplace, so ask your safety adviser if unsure.
