WELDMAX FUME FILTER 3PC SET SUITS WMXFEMHD

Weldmax Fume Filter 3PC Set – Suits WMXFEMHD & WMXFEMHD2

A complete filtration refresh in one kit. This 3-piece set covers every stage of filtration for the Weldmax WMXFEMHD and WMXFEMHD2 extraction units — spark arrestor, pre-filter, and particle filter — rated to E12 efficiency, so you're replacing the full filtration chain rather than guessing which single stage needs attention.

Why it matters

Multi-stage filtration only works if every stage is in good condition — a worn spark arrestor lets debris through to the pre-filter, a clogged pre-filter shortens the life of the fine particle filter behind it, and a degraded particle filter drops your actual capture efficiency even if the unit sounds and runs the same. Replacing the full set together keeps your WMXFEMHD or WMXFEMHD2 performing at its rated E12 efficiency, which matters for maintaining real fume capture as Australia's welding fume exposure limits tighten under the WES-to-WEL transition, effective 1 December 2026.

What's included

• Spark arrestor — the first line of defence, catching sparks and larger debris before they reach the finer filter stages
• Wavy filter (pre-filter) — coarse-stage filtration that protects the particle filter and extends its service life
• Pocket filter (particle filter) — fine-stage filtration delivering the unit's E12-rated efficiency

Key features

• Full set, one order — all three filtration stages covered in a single kit, rather than sourcing each separately
• E12 rated efficiency — high-efficiency particulate filtration suited to welding fume applications
• Direct fit — purpose-built for the WMXFEMHD and WMXFEMHD2 units

FAQ

Do I need to replace all three filters at once, or can I do them separately?
This kit is designed as a matched full-set replacement, since the three stages work together — the spark arrestor and pre-filter protect the finer particle filter, so replacing the whole set at once keeps the system balanced and gives you the rated E12 efficiency.

How do I know when the filters need replacing?
Reduced suction at the extraction point, more frequent unit alarms (if your model has filter monitoring), or a noticeable increase in visible fume in the workspace are all signs it's time for a filter change.

Is this compatible with older Weldmax fume extraction units?
This set is specifically matched to the WMXFEMHD and WMXFEMHD2 models — confirm your exact unit model with QWS before ordering if you're unsure of compatibility.

What does E12 rating mean for my workshop?
E12 is a high-efficiency particulate air filtration class, meaning the filter captures a very high proportion of fine welding fume particulate — important for keeping airborne exposure down in enclosed or high-throughput welding areas.
