AirClean Systems’ Patriot Ductless Fume Hoods hoods incorporate much of the technology of the company’s Independence fume hood with the backbone of its AC4000 folding and sliding-sash ductless unit. Patriot ductless fume hoods feature the AirSafe NXT automatic safety controller for added operator safety. This color touchscreen controller automatically increases or decreases blower speed to maintain the user’s pre-set face velocity, ensuring airflow is within standard operating parameters.
The current face velocity is displayed at all times. AirSafe NXT also monitors the bonded carbon filtration bed, alerting the user audibly and visually should filter saturation occur. Patriot features an application confirmation sequence that is required with every use of the hood. AirSafe NXT displays the approved chemical class for the hood, and waits for a confirmation from the user before allowing the hood to be used.
In addition to safety features, AirSafe NXT also provides a multi-language and multi-unit capability. Users can switch the controller language between English, Spanish, French and German. Airflow can be displayed in both linear feet per minute and meters per second. 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. It also features seamless, thermally welded polypropylene construction.
