Axial Fans

An axial fan is a device that creates airflow by using a motor to rotate an impeller housed within a frame. The circulating blades draw air into the fan and expel it on the same parallel axis as the spinning shaft, thus the term axial. The primary function of the axial fan is to cool and produce a difference in pressure. Fans work by drawing air across a surface to cool it. Fans are also excellent at moving large volumes of hot or warm air away, also creating a cooling effect. Axial fans are a vital component ensuring the smooth operation of machinery and electronic equipment. Keeping equipment cool is essential as overheating often leads to serious complications including premature deterioration of parts, shorter life spans and sometimes, a complete failure. Axial fans are used in a wide range of industrial and domestic cooling and ventilation applications across almost every industry. They are commonly installed in electrical cabinets and enclosures to keep components cool and prevent premature failure. Silent axial fans are often used in server racks to maintain the temperature of expensive equipment such as hubs, routers, and patch panels. In production line areas where motors operate continuously, axial fans help prolong motor and gearbox life. Compact computer fans are also found in PC desktop towers and laptops to keep internal components cool. Additionally, axial fans play a key role in ventilation systems by removing large volumes of warm air from enclosed spaces to stabilize temperatures.

Selecting an Axial Fan

The type of axial fan depends entirely on application and environment. Several factors must be taken into consideration when selecting the most suitable. Some key points to consider include:

Supply voltage - When selecting an axial fan, consider whether it needs to operate on AC or DC power. AC fansare ideal for mains-powered applications and are commonly used in industrial environments where consistent airflow is required. DC fans, such as **5V **models, are perfect for compact electronics like PC towers and laptops, offering efficient cooling in smaller spaces. For specific industrial or regional requirements, **110V **models provide a reliable solution for specialized setups. Choosing the correct voltage ensures compatibility with your system and optimal performance.
Fan speed - High or low speed?
Noise level - Does the application require a silent fan?
Static Pressure - What is the resistance to the airflow?
Ingress protection - Does the axial fan need to be IP55 rated or above?
Air-flow - What volume of air is needed to cool the area?
Shape - Square flanged or circular?
Size - 40mm, 50mm,60mm, and 80mm
