This portable, single-user system requires no installation, offers flexible operation, has a small, space-saving footprint, and matches the air flow (50 CFM) of large multi-user systems. Features quiet operation (<55db) and a bi-colored LED light to indicate blocked filters. Set the 12" wide plenum on the bench and turn it on for instant fume extraction. Harmful and irritating fumes, particles and vapors are immediately removed from your operator's breathing area. If you need the flexibility to move the collection device to the source of the fumes, an innovative adapter (included) transforms the plenum into an arm extraction system.Two models to choose from.
