Why provide diffusers?<br />
<strong>Axial</strong>-flow fans generate a total pressure<br />
increase (�pt) which comprises<br />
a static pressure portion (ps) and a<br />
dynamic one (pd). The impeller of an<br />
axial-flow fan consists of blades and<br />
hub located in the airflow. The result<br />
is a circular flow of considerable velocity.<br />
This high flow velocity (c) gives<br />
rise to a high dynamic pressure.<br />
When an axial-flow fan is allowed to<br />
discharge freely into a room, as is<br />
often the case, the entire dynamic<br />

pressure (related to the annular<br />
cross section) ceases to be effective<br />
and must be considered a loss. A diffuser<br />
will reduce the outlet velocity<br />
substantially and thereby prevent<br />
much of this dynamic pressure loss.<br />
In other words, to achieve an otherwise<br />
identical static pressure difference,<br />
the total pressure increase to<br />
be generated can be reduced, and<br />
so can be the output of the fan motor.<br />
Another benefit lies in the increased<br />
outlet surface area, which results in a<br />
