An industrial fan blower works by using rotating blades, known as impellers, to create airflow, either for ventilation, air circulation, or moving air and particulates. The impeller, driven by an electric motor or other power source, increases the air’s velocity and pressure, forcing it to flow through ducts or vents. Depending on its design—centrifugal or axial—the blower can handle varying pressures and flow rates, making it suitable for industrial processes like cooling, exhaust, or dust collection.
