Figure 6.4. - The correct fan for the application

In-line Centrifugal or

Mixed Flow Fan

In-line Centrifugal

Fan

Axial Fan

Don’t use a centrifugal blower if space is at a premium and

avoid unnecessary bends.

Do consider the space saving advantages of an in-line fan. It

can be centrifugal, mixed flow or axial, the selection being

governed by the fan duty and noise level required.

Figure 6.3. - Inlet plenums

Ensure eccentric flow is not caused by inlet plenum.

With a single width fan the airflow takes a single turn to enter it;

eccentric flow is created.

Selection of a double inlet fan improves airflow. Central

positioning of the fan and plenum entry grille will also assist.
