Patriot ductless hoods incorporate much of the advanced technology of AirClean’s Independence fume hood with the cost effective backbone of AirClean’s AC4000 folding and sliding-sash ductless fume hoods.   
   
Patriot ductless fume hoods feature the easy-to-use AirSafe™ TOUCH 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 TOUCH also monitors the bonded carbon filtration bed, alerting the user audibly and visually should filter saturation occur. Patriot features a unique ‘application confirmation’ sequence that is required with every use of the hood. AirSafe TOUCH displays the approved chemical class for the hood, and waits for a confirmation from the user before allowing the hood to be used.
