KEMPER SMARTFIL 3M FLEX ARM
Kemper SmartFil Mobile Fume Extractor
The Kemper SmartFil is a compact, mobile fume extraction unit built for regular welding use with medium fume and dust levels — a genuine middle-ground option between a basic occasional-use extractor and the heavier-duty ProfiMaster. Its standout feature is filter surface: at 25 m² (with a 42 m² high-capacity filter also available), it's larger than most units in its class, translating to a longer run time before the filter needs changing — Kemper rates the standard filter at around 30 reels of 1mm MIG wire before replacement is needed, or roughly double that with the high-capacity option.
The disposable filter changes out completely contamination-free once saturated, and W3/IFA certification means it's rated for high-alloy and stainless steel fume, not just mild steel. A rotating, swivelling hood with integrated lighting keeps the weld zone visible without extra positioning fuss.
Available arm configurations: 2m, 3m or 4m, in either flexible hose or rigid metal-pipe arm styles. Available in 110V, 240V and 415V.

Frequently Asked Questions
How long does the SmartFil filter last before it needs changing? Kemper rates the standard 25 m² filter for roughly 30 reels of 1mm MIG wire before replacement; the optional 42 m² high-capacity filter roughly doubles that.
Is SmartFil suitable for stainless steel? Yes, it's W3/IFA-approved for the carcinogenic fume produced when welding high-alloy and stainless steels.
What's the difference between SmartFil and SmartMaster? SmartFil has nearly double the filter surface (25 m² vs 13 m²) and is rated for regular, more frequent use. SmartMaster is the entry-level option, built for occasional, lighter-duty welding.
