The AirMax fume hood protects technicians from dangerous chemical exposure and also protects the ductwork and the environment by scrubbing acids and other water soluble gases from the fume hood exhaust. This fume hood has a wet fume scrubber system and is constructed of thermoplastics, primarily polypropylene, with all contact surfaces utilizing seamless, thermally-welded joints. This eliminates the potential for corrosion commonly associated with metal fume hoods. The rolled-entry airfoil design prevents reverse flow and eddy currents, while an extended rear baffle removes any heavy gases or evaporation from a spill. Dual-wall design provides ample room for mounting fixtures and services. The hood is suitable for trace metal analysis, hot acid etching, acid digestions and other high-volume, high-acidity processes. An optional spray bar for perchloric acid use is available, as is an auto pH dosing system for the holding tank. They are available in 36”, 48”, 60”, 72” and 96” widths.
