Weldmax FumeVault Replacement Filter Cartridge – M-Class
Keep your FumeVault fume extractor running at full filtration efficiency with this genuine M-Class replacement cartridge — the same horizontal filter used across the entire FumeVault EC range, from single-arm units through to dual-arm and W3 configurations. Rated to filter toxic industrial dust at better than 99.9% efficiency, it's the part that does the real work behind your FumeVault's clean-air performance.
Why it matters
A filter cartridge is a consumable, not a set-and-forget component — as it loads up with welding fume particulate, filtration efficiency and airflow both drop, even if the fan and motor are running perfectly. Keeping a genuine M-Class cartridge in your FumeVault matters for maintaining real-world capture performance as Australia's welding fume exposure limits tighten under the WES-to-WEL transition, effective 1 December 2026 — the certified 99.9%+ efficiency only holds if the filter itself is in good condition.

FAQ
Which media option should I choose?
Standard M-PES suits general welding fume and dust. If you're working with stickier or finer residues, the PTFE membrane option holds up better. For high-alloy steel welding (stainless, chrome, nickel alloys), the Membrane-H variant is purpose-built for that fume type.
How many cartridges does my FumeVault need?
The single-arm FumeVault EC uses 1 cartridge; the dual-arm and W3 models use 2 cartridges running simultaneously — check your unit's configuration before ordering.
How do I know when it's time to replace the filter?
A drop in suction at the hood, more frequent automatic cleaning cycles, or a rising pressure differential (if your unit has a gauge) are all signs the cartridge is nearing the end of its service life.
Is this compatible with older FumeVault units?
This cartridge is used across the current FumeVault EC range — if you have an older unit, confirm the model with QWS to make sure the fitment matches.
