Kemppi Air Fed Parts FAQs

Spares for powered and air-fed welding helmet systems, and how to work out the right part for your set-up.

Why can't I use a dust filter to protect against welding gases?

Particle filters only trap solid particles and fume. They do not remove gases or vapours, so a particle filter alone does not protect against gases produced by some welding and cutting work. HSE welding guidance makes the same point about the particulate filters used on disposable masks and half masks.

If your risk assessment says gas or vapour protection is needed, you need a filter specifically rated for that, and the system must be approved to take it. Check the markings on the old filter and the instructions for your unit, and ask the maker or our team if you are unsure which type your system uses.

What should I check on an air-fed helmet system before each shift?

Check the whole system before every use. HSE guidance says employers should confirm RPE is working before each use, and a powered system needs a quick look at the battery condition and the airflow indicator or low-flow warning, as set out in the maker's instructions.

Also look at the filter and spark guard (fitted, clean, undamaged), the breathing tube (no cuts, kinks or loose ends), the face seal and headband, and the cover lens. If the airflow warning sounds, the battery is weak or anything is damaged, stop and fix it before welding. Do not rely on a system that is not giving its full airflow.

Can I wear an air-fed or powered helmet with a beard?

It depends on the type of facepiece. HSE guidance says tight-fitting masks rely on a seal against the skin, and stubble or a beard stops a good seal. Loose-fitting powered helmets and hoods work differently: the unit keeps a flow of clean air through the headtop, so they need no tight seal.

That said, there are limits. Makers usually set limits on facial hair and the helmet must be the right size and correctly adjusted for the wearer. Check your unit's instructions and your employer's RPE assessment, especially where the system includes a separate face seal.

How often should an air-fed helmet system be examined, and what records are kept?

The maker's instructions set the examination and replacement periods, including any shelf lives for parts such as filters. HSE guidance says reusable powered RPE should have a thorough examination and, where appropriate, testing at least monthly, or every three months if it is used only occasionally, carried out by a competent person following the maker's instructions.

This normally includes a visual check, battery condition and airflow. Keep records of examinations, tests and repairs for at least five years. Where parts need replacing, they should ideally come from the original maker. Your employer's risk assessment decides anything beyond these minimum checks.
