The Zephyr® III portable dust and fume collector combines three-stage filtration with versatility and ease of use. Applications include welding fumes, grinding dusts, dry dusts, soldering fumes and other airborne particles. Equipped with large wheels and brakes for easy movement and positioning, the collector is a self-contained unit: The user simply plugs in the 110v/1 Ph. 60 Hz power cord and compressed air line, installs the fume arm, and the unit is ready to capture dust and fumes. Contaminants entering the collector are removed by three stages of filtration: a metal filter that functions as a spark trap, a main filter for fine particle removal, and a carbon final filter for odors and gases.
