Industrial facilities are routinely faced with the need to clean the air of harmful fumes resulting from indoor welding and grinding. One of the more challenging aspects of indoor weld smoke collection is complying with the recent change to the OSHA permissible exposure limit (PEL) for welding fumes containing hexavalent chromium. Hexavalent chromium filtration calls for a HEPA post filter and most of the items pictured here can be fitted with a HEPA. This page profiles some options in portable weld smoke collection along with industrial downdraft tables and flexible source capture arms. The items below are a cross section of the models available for each category and please contact us if you are not finding a unit that will address your application because we have the resources to locate the equipment you need.
