Axial Flow Fan Applications: Suitable for ventilation and air exchange in metallurgy, chemical industry, light industry, food, machinery and equipment, as well as civil buildings to enhance heat dissipation. Without the housing, it can also be used as a fan. It can be installed in series at intervals in longer exhaust pipelines to increase wind pressure within the pipeline, being a fan where the airflow direction is the same as the axis of the fan blades.
