Ductless Fume Hood – Generation II helps protect the operator and environment from hazardous fumes or particulate generated from applications performed within the hood. The new and improved design of this fume hood includes an adjustable light, variable speed fan control, and a digital display with an hour counter and digital magnehelic gauge. The adjustable light and fan controls enable the operator to make modifications suitable for the application. The digital hour counter shows the time the unit has been operated in hours to keep PM schedules for filter changes. The digital magnehelic gauge measures the static pressure on the filter in order to monitor the filter saturation. This unit also features an external reset button and programmable alerts.
