We recommend IFA mobile welding fume extractor units certified W3, as they offers a minimum specification hallmark around air flow rates, filter efficiency & filter alarms. Check the manufacturer product specifications for evidence of compliance.
Choosing between filter & self-cleaning mobile LEV welding fume extractors
Where fume levels are relatively low, such as in a maintenance environment, a portable filter unit such as the Kemper Smartmaster would do the job, as the churn on welding filter replacement would be low. This unit isn't suitable for grinding operations though, as it doesn't have a spark arrestor. A better choice for a moderate amount of grinding, would be the ProtectoXtra, which comes ready fitted with a spark arrestor & has a bigger filter capacity.
More industrial settings ideally suit a self-cleaning unit akin to the Protectoxtra. This cartridge based model has a bigger footprint, but allows you to blow the metal particulate into a waste bin for disposal. With no filter changes, ongoing maintenance costs are reduced to the minimum.
Welding Fume extraction surveys
With a good number of portable extraction choices in the market place, choosing the correct one for your application can be tricky. Our Technical field engineers, can visit site, perform a Welding fume survey.
The survey measures fume levels, using a monitoring unit that can be moved around the workspace offering time specific events around welding fume & metal particulate levels. This assists in recommending and installing the correct portable LEV unit.
