Industrial High Temperature Induced Draft Fan is generally used in forging furnaces and high-pressure forced ventilation. It can also be used to transport hot air and gases that are non-corrosive, non-spontaneous, non-explosive, non-volatile, and non-sticky. The air inlet is integrated into the side of the fan, and the section parallel to the axial direction is curved, so that the gas can enter the impeller smoothly, and the air loss is small. The induced draft fan and the connecting pipe are matched with the granular fertilizer dryer.
