FD press in counter rotating fan

FD press in counter rotating fanUsed in high-pressure ventilation areas such as metallurgy, non-ferrous metals, gold, chemical, shipbuilding, and ceramic industries. Its structural features include counter rotating, noise reducing, and axial flow for mining use.This product has the characteristics of reasonable structure, complete specifications, high efficiency, obvious energy-saving effect, low noise, and long air supply distance. According to different ventilation resistance requirements, it can be used as a whole machine or in stages, thereby reducing ventilation power consumption and saving energy.The gas temperature in the environment where the fan is used is -20 to 50 ℃. The rated frequency of the power supply used is 50Hz, and the rated voltage is either 380V/660V or 660V/1140V. The product features areThere are two impellers installed close to each other, driven by two motors to rotate in opposite directions. The airflow enters the first stage impeller along the axial direction from the collector end, and the direction of the airflow is deflected and flows into the first stage impellerⅡLevel host, managed byⅡAfter the stage impeller accelerates again, the airflow direction reverses and is discharged from the diffuser end along the axial direction.
