Buying Mobile Fume Extraction
In our view, businesses need to take a holistic approach to welding fume control & extraction, as buying an air fed welding helmet alone to protect the welder is not enough. You need to clean the air for other operatives in the workplace, such as fork lift drivers and factory staff.
With reduction of third party welding fume inhalation coming to the fore, current thinking is that W3 compliant weld fume equipment will be a necessity going forward. In basic terms, W3 guarantees a number of key elements are in place: a minimum air flow of 10 metres per second, a filter efficiency of 99% or greater & a audible/visual low air filter alarm.
Here are some product options to consider, listed by filtration method, application & duty cycle:
1./ On MIG torch extraction with mobile fume eliminator.
In terms of fume removal, the on MIG torch option is by far the most effective with up to 70% of the fume being captured.
The Foster Prem-X-200W3 extractor with Binzel RAB torch is a lightweight & mobile solution, which extracts the welding plume down a adjustable MIG torch nozzle.
The efficient integrated cleaning device on the Prem-X-200W3 allows compressed air to be connected to the unit increasing filter life, whilst a filter gauge flicks into the red as a visual alarm when the filter needs cleaning.This unit boasts an automatic start-stop feature which can be connected to the torch or earth lead, minimising noise whilst improving the service life of the motor.
An alternative to the Prem-X-200 is the lighter duty Kemper Minifil high Vacuum extraction unit. It has the necessary W3 compliance & contamination free filter change, but has a smaller filter & motor capacity than the Prem-X. It's an ideal purchase for a maintenance facility. For heavy industrial applications, talk to us about Kemper's Vacufil 125 & 500 systems.

2./ Light duty portable fume extractor for maintenance environments.
Kemper Smartmaster: Great entry level fume extractor suitable for low level fume, occasional grinding & W3 compliant. In practical terms, the main filter will need changing after every 15 reels of MIG wire consumed.
-The unit will filter mild steel, stainless steel & other high alloys metals and is available in 110 or 240 volt, with swivel hood, 2 or 3 metre arms.
-Three filter system includes pre-filter mats, pre-filter & main filter.
ProtectoXtract; Brilliant if you want to grind as well as weld, as you can retrofit a grinding filter-unique in the industry. The amazing five part filter system covers all bases:
-Gross filter; Disposable & lasts 40 to 70 hours.
-Prefilter; Removes large particles.
-Carbon filter; Takes out nasty smells & odours.
-Main filter (sub-micro): Removes metal particles.
-Retrofit spark filter(for grinding):A metal deflector plate sends sparks into a catch box. NOTE; This a must have optional extra if you are grinding & polishing.
This model is available in a 3 metre arm version only with 110 or 240 volt input. Carries W3 compliance.
NOTE; A ProtectoXtract machine purchase comes with a free COSHH test & commissioning, meaning you are fully compliant. (Offer does not extend to customers in Northern Ireland & Scottish borders)
3/.Medium duty portable options.
Kemper Profimaster; Industrial fume extractor for regular use, with 360 degree rotatable hood & W3 compliance. In an everyday environment, the filter will need changing after every 30 reels of MIG wire consumed.
-Suitable for low to medium levels of fume.
-Suitable for high alloy, mild steel fume.
-Available in 110, 240 & 415 volt models with 2, 3 & 4 metre rotatable arm options.
-Easy change two filter(pre & main) system was a nice enhancement from the previous Filtermaster model.
4./ Heavy Duty Self-cleaning options
In industrial environments where a lot of anti spatter is applied or the fume created is heavier from dirt & grease, it is important to consider the filter life. DON'T make the mistake of buying a light duty machine for a harsh environment & then rip through filters.
A self cleaning machine cleans itself, filters lasting up to 6,000 welding hours. Importantly, the filters can be removed & pressure washed.The Plymovent Mobile Pro provides such a solution & the fitting of an aluminium KUA arm gives it a heavy duty feel.
5/. Downdraft Bench options
A downdraft bench offers a great solution, where it isn't practical to have fume arms suspended from above. Benches of this nature are typically used in colleges & maintenance environments & suitable for grinding, sanding, polishing & welding applications.
The ProtectoXtracTop is a great option for those looking for a portable downdraft bench solution. A spark filter is fitted as standard(for grinding purposes) into a ProtectoXtract system which sits under the perforated work area.
With a working surface area of 1100 x 700mm, fumes are drawn away from the operator's breathing zone & into the ProtectoXtract unit for filtration.
*The ProtectoXtractop down draft bench type is ideal for welding, grinding & polishing.
