Description
The conventional parallel blade shape is often an effective cooling solution. However, the need for reduced power consumption and less noise has led to the development of alternative blade profiles, which offer advantages for certain applications. For example, the conventional metal blade form effectively spreads air to the corners of the radiator core where the fan is relatively small. However, the Truax blade is narrower at the tip, which produces a more axial flow, and can save power. Likewise the sickle shaped blade, which is wider at the tip, reduces noise in applications where this is critical.
Applications
For use when reduced power consumption and/or less noise is critical.

Description
The fully reversible fan is essentially a spider fan with a special blade profile.
Applications
The efficient symmetrical cross section means that in emergency situations the fan motor can be reversed to give an airflow in the opposite direction. |
