Quadrafoam air filters help HVAC, general industrial, and other applications meet the UL 508A safety requirements intended for industrial controls 600 V or less, in preventing arc flash and shock hazards within the prohibited approach boundary. According to the manufacturer, the filters can be beneficial in HVAC markets for variable frequency drives for controlling fan speeds and other equipment used in energy management systems. The filters provide a protective barrier between the internal controls and the panel exterior. The nonconductive filters can be installed along the interior face of the ventilation openings in the panel.
