Weldline Silver Zeyphyr Flip Air LS PAPR Parts FAQs

Filters, batteries, hoses, straps and helmet parts for a powered air respirator welding helmet, and how to choose and look after them.

Which parts of a powered air welding helmet system wear out and need replacing?icon-minus-redicon-plus-red

The HSE lists the key maintenance tasks for powered respirators as changing replaceable filters, cleaning the device, checking the straps for damage and checking the battery charge and flow rate. In a welding helmet system that usually means the main particle filter, any pre-filter, the battery, the breathing hose and its cover, the belt or shoulder strap, and the helmet's own seals, lenses and headgear.

How quickly each wears depends on the work, the fume level and the maker's instructions, so use the manual as your guide.

How do I pick the right replacement particle filter?icon-minus-redicon-plus-red

Match it to the type the maker specifies for your blower unit, using the manual or the marking on the old filter. Particle filters are marked P1 (low efficiency), P2 (medium) and P3 (high), according to HSE guidance. Welding fume is a particulate hazard. For arc welding, HSE welding guidance recommends powered or supplied-air equipment with an assigned protection factor of at least 20, and it names P3 as the filter level for half masks.

A particle filter does not protect against gases or vapours. If your work produces them, ask the maker or your risk assessor about a combined filter before choosing.

How often should the main filter be changed?icon-minus-redicon-plus-red

There is no single interval. The HSE says replaceable filters have a limited capacity and can clog, so they should be changed as the manufacturer instructs and whenever they are damaged, visibly contaminated or when airflow drops.

How quickly a filter loads depends on the amount of welding, the fume produced, the material and the working conditions. Low airflow or a warning from the unit is a sign to stop and check the filter and battery. Fit identical filters together if the unit takes more than one, and change them all at the same time. Never run the unit without the filter fitted.

What does a pre-filter do, and can it replace the main filter?icon-minus-redicon-plus-red

A pre-filter is a coarser layer that catches larger particles such as dust and spatter debris before they reach the main filter, so the main filter lasts longer and stays cleaner. It is usually changed more often than the main filter.

It is an addition to the main filter and not a substitute for it: the main particle filter is what provides the stated protection. Fit the pre-filter the way the manual shows, because a loose or badly positioned one can restrict airflow or let debris past. Follow the maker's advice on when to change it.

How should I look after the battery?icon-minus-redicon-plus-red

The HSE says to make sure battery-powered RPE is fully charged before use and to check the battery charge as part of regular maintenance. Charge it with the charger supplied or specified for it, store and charge it as the manual describes, and replace it when it no longer lasts a full shift or no longer charges properly.

Batteries of different capacities or styles are often made for the same unit, so check that the type you order is listed for your blower. Spare batteries are useful for long shifts, but always check the airflow after fitting one.

How do I check the airflow, and what do I do if it drops?icon-minus-redicon-plus-red

Always check that the fan is providing enough airflow before you use the device, following the maker's airflow check in the manual. The HSE guidance is clear that you should never keep working if the fan stops or the flow rate falls: leave the work area immediately. If your unit has a low-flow warning, treat it the same way.

Then check for a blocked or loaded filter, a flat battery, a kinked or damaged hose or a loose connection. Do not return to work until the fault is corrected and the airflow check passes. If you cannot find the fault, have the unit examined by a competent person.
