FINDING THE BEST SOLUTION ı

To determine the filtration best suited to your facility, begin by considering the current level of activity, as well as what's likely in the future.  Ambient air intake filtration, where plant dusts and welding emissions are filtered together, may suffice if there's just one welding operation, and welding is incidental.  (If this is the case click here to see information regarding Selecting "Free Hanging" Ambient Air Filtration Equipment 5 Step worksheet to help in the selection process.) 

Where welding is multi-station or ongoing, source capture, through the use of an air intake hood system in close proximity to the workstation, will be needed to be effective.  By "effective" we mean capable of capturing, efficiently and consistently, both fumes and heavier particulates.  The second part of being "effective" is that the device can do its work for extended periods, and without creating a maintenance issue.

If source capture is required, the first step is to quantify the airflow required to draw fumes and fine particles away from the welder.  As a practical matter, to collect all particulates would require such a huge airflow that it would detrimentally affect the welding process.  So, the largest particulate will not be extracted.  The collection of fine particles and the fumes that OSHA regulates is the mission.  OSHA Standard 29 CFR 1910.1026
