Buy Fume Extractors Online in Australia
AIMS Industrial stocks five welding fume extractors, all from Bossweld's BT Weld range — the practical entry point for keeping MIG, TIG and plasma welding fume out of the operator's breathing zone. The range covers two genuinely different approaches: the BT Weld EXT-1, a 240V torch-mounted (on-torch) unit that captures fume right at the MIG nozzle, and the BT Weld EX-10 / EX-15 / EX-30 workshop units, which sit beside the bay and pull fume in through a hood or arm. Because it's a tight range rather than a sprawling catalogue, the job here is simple: match the extraction method and motor size to how you weld, then get the filter consumables sorted so the unit keeps performing. Our Workshop Ventilation & Fume Extraction: AS/NZS 1668.2 + Source Capture walks through the key differences if you're comparing options.
Why source extraction matters
Welding fume contains metal oxide particles fine enough to reach deep lung tissue, along with flux compounds and, on some processes, ozone. Safe Work Australia's guidance treats welding fume as a genuine respiratory hazard, and stainless steel work in particular releases hexavalent chromium — a substance with a very low workplace exposure standard. The WHS framework asks employers to control airborne contaminants at the source first, ahead of relying on general ventilation or respirators alone. A fume extractor positioned close to the arc — within roughly 300 mm — does that job far more effectively than an extraction fan or open shed doors ever will.

Airflow (m³/h) is only published for the EXT-1 units above; the EX-10/EX-15/EX-30 are specified by motor power rather than a stated m³/h figure. Talk to our team if you need an airflow figure for a compliance or ventilation calculation — we'll pull it from the manufacturer's data sheet.
How to choose between them
On-torch vs workshop unit
The BT Weld EXT-1 puts the extraction point on the MIG torch itself, so fume is drawn away right at the arc — the most direct form of source capture, and a good fit for one welder doing continuous MIG or flux-cored work. It comes either bundled with a matched torch (24 Style/250A, 36 Style/340A or 501 Style/500A, in 4m or 5m lengths) or as the extraction unit alone (681010) if you already run a compatible torch and just need the extraction side. The EX-10, EX-15 and EX-30 instead use a hood or arm positioned near the weld pool, which suits changing weld positions, TIG and stick work where an on-torch system isn't an option, or a bay shared loosely between tasks.
Sizing by motor power and phase
Within the workshop units, motor power is the practical sizing cue: the EX-10 (0.75kW, 240V single-phase) suits a single welder on light-to-moderate duty and runs off a standard power point. The EX-15 (1.5kW) and EX-30 (3kW) both need 415V three-phase supply and step up in capacity — the EX-30 is the largest unit in the range and the one to look at for a busier bay, heavier material, or where one extractor needs to keep up with more welding hours per day. Confirm three-phase power is available at the bay before specifying an EX-15 or EX-30.
Filter care
Every unit in this range works through a replaceable cartridge filter — the EXT-1's PET cartridge is rated 99.90% capture down to 0.3 micron, and AIMS stocks the matching replacement (681011) so the unit isn't left waiting on a filter. A cartridge that's never checked or replaced protects nobody; treat filter condition as a maintenance item, not a set-and-forget purchase, especially on galvanised or stainless work where the fume load is heavier.
Brand in this range
All five units come from Bossweld's BT Weld fume extraction line — we've kept this range deliberately tight to what we can back with genuine local stock and support, rather than list units we can't service. If you're speccing extraction for a new bay or a multi-welder workshop and want a second opinion on which model fits, contact our team — we can talk through duty cycle, power supply and filter consumables before you buy.
Round out the welding safety setup
A fume extractor is one layer of a welding safety setup, not the whole thing. Pair it with a properly fitted respirator as backup protection, an auto-darkening welding helmet, and welding gloves and welding jackets for the rest of the PPE stack. Browse the wider welding equipment and consumables range or the full safety equipment and PPE collection for everything else the bay needs.
Fume extractor FAQ
Do I need a fume extractor for MIG or TIG welding?
If welding is a regular part of the job, source extraction is the primary engineering control under Australian WHS regulations — general workshop ventilation or an open roller door isn't treated as sufficient on its own, particularly for stainless, galvanised or coated material. A portable or torch-mounted extractor at the weld point is the standard, defensible answer for most workshops.
What's the difference between the EX-10, EX-15 and EX-30?
They're the same style of workshop extraction unit at three motor sizes: EX-10 is 0.75kW on 240V single-phase, EX-15 is 1.5kW on 415V three-phase, and EX-30 is 3kW on 415V three-phase. Step up through them as welding duty, bay size or hours of daily welding increase, and check three-phase power is available before choosing an EX-15 or EX-30.
How is the EXT-1 different from the workshop units?
The EXT-1 extracts fume directly at the MIG torch nozzle rather than through a separate hood or arm, so capture happens right at the arc. It's available bundled with a matched torch or as the extraction unit alone (681010) if you're fitting it to a torch you already own.
Can I buy the EXT-1 without a MIG torch?
Yes — the BT Weld EXT-1 (681010) is the same extraction platform sold as the unit only, for workshops that already have a compatible torch and just need the extraction side.
Do these units need single-phase or three-phase power?
The EX-10 and both EXT-1 options run on standard 240V single-phase power. The EX-15 and EX-30 require 415V three-phase supply, so confirm that's available at the bay before ordering.
How often does the filter need replacing?
It depends on the process and material — clean steel on a shielded process is far gentler on a filter than galvanised or flux-cored work. Treat filter condition as an ongoing maintenance item rather than a fixed calendar date, and keep a spare cartridge on hand (681011 for the EXT-1) so the unit isn't out of action waiting on stock.
