Side Discharge

The side discharge option provides several advantages including removal of a system effect problem, increasing performance, or even reducing installation labor. The most notable is reducing system effects. Notice the example in figure 1 showing the air being discharged into the corner. It will take several duct lengths before the airflow becomes smooth again after making the turn. This is not the case with a side discharge. See figure 2; when the air comes into the fan at the corner and leaves the fan at the corner, the airflow is smoother and provides a more predictable system. Remember the duct length prior to or following the installation location should be approximately two to three wheel diameters to achieve catalog performance.

Discharge Configuration

Make sure the fan discharge is oriented in the same direction as it was originally ordered. The performance will change with different discharge positions. Right side discharge will give you 108% of cataloged performance and left side will give you 109% of cataloged performance. Use figure 3 to locate the orientation to fit your application. Figures 4 and 5 explain the proper side discharge definitions. Refer to the CAPS program or consult factory for performance modifications.
