Mystaire is pleased to announce the release of Aura ductless chemical fume hoods. Each hood has advanced safety monitoring and controls and is ASHRAE 110 tested. The included microprocessor safety controller monitors and adjusts fume hood face velocity to the user preset value for the containment of potentially toxic gases and vapors. A Filtrak positive filter sealing system is installed in each hood. This 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. The fume hoods are available in 30, 42 and 54 inch widths and ESD models are available for applications involving volatile chemicals.
