Portable welding-fume extractors and exhausters are carried to the work location to filter and remove harmful welding gases, vapors, and fine particulates. Portable fume extractors are a good choice for remote welding tasks and work in small shops or confined spaces. Removing contaminants from air helps meet OSHA requirements and prevents buildup gases and harmful toxins that can affect worker health. Portable units produce a high-pressure draft and have a small diameter hose so they need to be placed closer to the workpiece.
