External Rotor Axial Fan Applications in HVAC and Electronics

  • click to rate

    The Multi Wing Fan Factory series of External Rotor Axial Fan units has been adopted in a variety of scenarios where airflow must be delivered in constrained spaces or where quiet operation matters. Taizhou Haoba Electromechanical Co., Ltd. provides units for air conditioning systems, electronic equipment cooling, medical device enclosure cooling, and building ventilation where ceiling or wall depth is limited.

    For example, in a large data hall where air handling units need to move large volumes of air through packed filtration modules, the External Rotor Axial Fan configuration reduces obstruction in the air path and allows easier access for service panels. Taizhou Haoba Electromechanical Co., Ltd. designed custom fans with modified blade shapes that improve airflow uniformity across the filter faces, reducing pressure drop and energy cost over time in that project.

    Another instance is in medical equipment cabinets where fan noise is a factor. Because external rotor layout often allows more direct airflow over housing surfaces and fewer internal shrouds, noise can be reduced. Taizhou Haoba Electromechanical Co., Ltd. supplied External Rotor Axial Fan units with special acoustic treatments (damping, housing ribs, sound-absorbing liners) for these cabinets.

    In cleanroom ventilation, the slim profile of external rotor fans helps when units are mounted behind walls or above ceilings where space is narrowly confined. Taizhou Haoba Electromechanical Co., Ltd. worked with a client to retrofit existing ductwork and replace bulkier fans with external rotor versions, resulting in improved airflow and easier maintenance access without sacrificing required cleanroom air exchange rates.

    Industrial ventilation – e.g., factories with welding, painting, or chemical processing – benefit from External Rotor Axial Fan units that can handle abrasive or moist air. Taizhou Haoba Electromechanical Co., Ltd. uses protective coatings, robust bearings, and materials (such as stainless steel or composite blades) in these contexts to resist corrosion, build-up, and extend service periods.
