The fan blades are turned by a brushless DC motor or an
asynchronous AC motor. Unlike centrifugal fans, axial models do not
operate at high pressure, but offer constant flow. These fans are
mounted in an air duct, a wall or partition. A bell mouth and a
diffuser enhance air flow and reduce noise. Output can be improved
by using a turbine wheel at the upstream or downstream guide vanes.
Some fans have two counter-rotating sets of blades, while others
offer enhanced performance by changing the angle of attack of the
blades.
How to choose
Choice will depend on nominal output flow, noise level, size, power
consumption and voltage. Aeration fan selection is determined by
the operating curves of the various models.
Advantages
- Easy installation
- Constant output
Disadvantages
- Low-pressure operation only
