    An axial fan is one in which the extracted air is forced to move parallel to the shaft about which the blades rotate. Most domestic wall fans use an axial impellar and are ideal for bathrooms, toilets and smaller rooms where the air is to be ducted straight through the wall or installed in a window.

    Axial fans have an arrangement of rotating blades which cause the air to be pushed or pulled in one direction. The arrangement of blades on the hub of the device is called an impeller or a rotor. The majority of these things are contained in housing or a specially designed case that will aid in the directing of the airflow while it protects the blades from coming into contact with other objects.

    It is possible to find axial fans in most modern households. These fans are the most common type of forced air cooling used in home electronics such as computers and televisions. In addition, many homes use ceiling fans, box fans or pedestal fans for air circulation. All of these fan types are usually axial fans.

    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.
