The Avantik containment hood systems are designed to enclose materials and operations under negative pressure, thereby preventing airborne contaminants from escaping into the work environment. Contaminated air is drawn through a variety of filters to remove pollutants. Filters are available for both vapors and particulates and they ca be combined for multiple substance filtration. Constructed of clear, 1/4" thick, acrylic panels with sturdy aluminum framing (other panel materials are available if required). They come equipped with a clear vinyl curtain providing easy access while maintaining optimal airflow across the opening. Available in four sizes. Each system comes with filters specific to your fume containment application.
