This type has various blade shapes including aerofoil, sickle, paddle, and variable pitch. Axial fans are used for relatively high flow rates and low pressures with flow parallel to the axis of fan. They also have low power input. They are generally selected for simple extraction or cooling applications with very low system resistance, such as moving air from one large space to another, desk fans, ventilation, and condenser cooling in refrigeration.
These barrel-shaped fans have curved forward blades that are generally many times longer than any given diameter. Tangential fans tend to scoop the air up and deliver it at relatively low pressure over a long length, ideal for cabinet cooling or process air coverage. Power required is relatively low. The main advantage of Tangential over axial fans is that they provide extremely smooth, laminar airflow over the whole frame width. This makes them suitable for applications such as air conditioning systems, air curtains, computer systems, instrument racks, convector fans, ovens, de-humidifiers and ventilators.
These combine the features of Axial and Centrifugal Fans by employing the air movement techniques of both. Air enters the inlet side of the fans and exhausts in an axial route from the outlet side. The pressure development of the mixed flow fan is greater that an Axial fan and is more akin to the Centrifugal fan.
