Gamma PFA with RSA 230 Parts FAQs

Spares and consumables for a powered or air-fed welding helmet system: how to identify the right part, what wears, and how to look after it.

Which parts of a powered or air-fed helmet system wear out and need replacing?

The HSE lists the key maintenance tasks for powered respirators as changing replaceable filters, cleaning, checking the straps for damage, and checking the battery charge and flow rate. In practice, the items that wear most are filters and pre-filters, hoses, belts and straps, seals, sweatbands, and the cover lens on the helmet.

How quickly each one wears depends on the work, the environment and the maker's instructions. Look over the whole system before each use, and replace anything cracked, stretched, torn, loose or contaminated rather than waiting for it to fail.

How do I know when a filter on a powered helmet system needs replacing?

Filters have a limited capacity and can clog, which makes breathing harder and reduces airflow, so the HSE says replaceable filters should be changed when necessary. Follow the maker's instructions for your system. Common signs are a filter indicator showing it is loaded, a low-flow alarm, a noticeably shorter battery run-time, or visible damage or dirt.

A maker's consumables guide notes that a pre-filter is usually changed far more often than the main particle filter, which helps the main filter last. Gas or vapour filters should be replaced according to your risk assessment and the maker's guidance, and you should not wait until you can smell something.

Why does it matter which hose I fit to an air-fed or powered helmet?

The hose carries the air you breathe, so it must be the right type for your system and your job. Different hoses are designed for different equipment, and the HSE warns that light-duty supply tubes must never be used for normal airline applications. The connectors, length and any pressure or flow requirements also depend on the maker's design.

Check the manual for the correct hose type, and look at the whole length and the end fittings before each use for cuts, kinks, crushing, burns from spatter and loose connections. Replace a damaged hose rather than taping it. The HSE says to look after the supply tube during use, because the wearer's protection depends on it.

How should I clean and store the hose, belt and helmet parts?

Follow the maker's cleaning advice. The HSE says that using cleaning products other than those the maker recommends may cause problems with the equipment, so avoid solvents and harsh chemicals unless the manual allows them. Clean and dry parts in a clean area so they are not contaminated again.

The HSE also advises cleaning equipment before it is stored, and storing it as the maker instructs, in a clean place that protects it from contamination, damage and deterioration. Keep the helmet from resting face down on the cover lens, and remove or disconnect the battery for long-term storage if the manual says so. Check the parts again before the next use.
