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. RS Components offer a range of high-quality axial fans in both AC and DC from leading brands including Sanyo Denki, ebm-papst, Sunon and of course RS PRO.
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.
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:
Axial fans are used in a wide range of industrial and domestic cooling and ventilation applications across almost every industry. Some of the most common places you will find them in use are:
Electrical cabinets and enclosures - Axial fans are installed to keep components cool preventing premature failure.
Server racks - Silent axial fans are used to keep expensive equipment like hubs, routers and patch panels cool.
Production line areas where motors are constantly in use, prolonging motor and gearbox life.
PC desktop towers and laptops feature compact computer fans to keep internal components cool.
Ventilation - Axial fans are also used to remove large volumes of warm air from an enclosed area to keep temperatures stabilized.
