The FT240F/A(F)/FT222F/FT245F inverter transport fan is used to transport raw material from the front different single machine to the next one.Those motors are driven by frequency inverter,so it can control the pressure and volume fo the air in the duct accurately.It ado-pts straight-blade aluminum-alloy im-peller which has a smooth oxygenated surface and features nosparkle,no black and no adhesion of fiber.Its surface is painted can be adopted.Fan's outlet angle can with plastic and it have a good antrust be 0°，90°，and 180°.The way of transperformance. One of two re volving missing is that the impeller and motordirections,clockwiseor anti-clock wise,connect directly.
