Eliminating the need for costly installation, the Patriot ductless hoods have an on-board energy meter, accessed via AirSafe TOUCH, to display the real-time and life-time energy use of the hood. Bonded carbon filtration is standard on all ductless fume hoods and for added application capacity, Silconazyne filtration is also available. Patriot’s rolled-entry design combined with AirZone baffling provides laminar flow within the cabinet, preventing eddy currents and keeping fumes or particulate from escaping the hood. These ductless fume hoods are shipped fully assembled, requiring very minimal installation. They can be set up within minutes of being removed from its shipping container and plug into a standard 110V or 220V outlet. Folding sash models are initially available in 36” and 48” widths, and sliding sash models are initially available in 48” and 72” widths.
