Axial fans are devices designed to move air or gas along the axis of the fan. They consist of blades that rotate around a central hub, creating airflow in a straight line. These fans are commonly used in various applications, including cooling systems, ventilation, and industrial processes. The efficiency of axial fans makes them suitable for large volumes of air movement with relatively low pressure. They are often found in HVAC systems, computer cooling, and air conditioning units, providing essential airflow to maintain optimal temperatures and improve air quality in different environments.
