  • AFL DC Axial Fan is a mechanical device that produces a flow of air or gas. These are used to move air and gases through ventilating systems. Serving various industrial needs, fans force air through steam boilers and lower the operating temperature of electronics and machinery. Unlike compressors, fans function in relatively low pressures. These are primarily categorized as centrifugal or axial. Centrifugal fans are the traditional types which are mainly used for ventilation like in ceiling-mounted fans. The air moves perpendicularly to the fan shaft. There are three general kinds of centrifugal blades, namely: radial, forward-curving and backward-curving. These produce more pressure for a given air volume and is used in hair driers, inflatable items and other similar industrial purposes.

    On the other hand, axial fans are widely used for small cooling fans for electronic gadgets, giant fans used in wind tunnels and various other applications. However, you may be familiar with these because they are typically used for the regular table fan. The blades of these type force air to move parallel to its axis of rotation. This fan's blades may be flat or curved plates or be shaped with cross sections akin to airfoils that give lift to an airplane's wing. There are of three categories, namely, the propeller, tube and vane. Propeller are used for pushing high air volume against low or no static pressure. Meanwhile, tub are those whose propellers are encased in a duct section. On the other hand, vane convert circular, twisting air movement into longitudinal, straight movement. Vane are considered the most efficient fans for HVAC systems. EC Fan: http://www.afl-fan.com/product/
