Vane-Axial – The vane-axial fans require much less area than centrifugal, and are cheaper. They provide excessive pressure.
Tube-Axial – Tube-axial fans additionally develop excessive pressure, however a draw back is the low-efficiency.
Impeller – Impeller fans are additionally referred to as flat packs. They’ve a terrific total circulation price in addition to pressure drop. The result’s small side ratios.

Each impeller and flat pack fans are nice for dropping pressure and are normally present in electronics which are packed tightly or densely. Centrifugal and axial can transfer air by way of however not as properly as a result of they’ve traits of pressure drop; then once more, they play an necessary position in cooling bigger areas in fan tray assemblies due to the quantity circulation price they produce.
