This AMS hood is portable, but must be connected to an HVAC system. The backward-curved 120 volt blower has a variable speed control to maximize efficiency and minimize motor noise. The blower unit sits atop a fully welded tube chamber with plexiglas windows for viewing from all four sides. The front has a fold-up door to allow for loading and unloading of apparatus and experiments.
