When selecting a ductless fume hood, it is essential to consider whether it offers the user the best protection possible. Mystaire Misonix’s range of Aura ESD ductless fume hoods for electrostatic-sensitive applications protect users against toxic fumes and provide electrostatic dissipative features to prevent static build-up and discharge. Each fume hood includes a safety controller that monitors and adjusts fume hood face velocity to the user preset value. A cam-driven filter sealing system has a built-in filter position indicator and alerts the end-user if the filtration bed is not properly sealed. They are available in 30-, 42- and 54-in. widths.
