ActronAir Indoor Evaporator EC Plug Fan K3G560FA2806 560mm 3-Phase is a 560mm FA-series EC plug fan for Tri-Capacity and Hercules commercial indoor units where the FA2806 motor variant is the factory-fitted specification -- always verify the installed motor model against the unit service label before ordering as multiple 560mm variants exist with different electrical interfaces. EC plug fan model identification is critical on commercial systems where ordering the wrong 560mm variant requires a return and causes extended downtime. Isolate power at mains before replacement -- EC motors and variable drives retain dangerous residual voltages for up to 5 minutes after power isolation.
