Select Next.

Equation

If you selected the Equation option, then the Fan Equation panel displays.

Enter the necessary fan equation parameters, that is, the starting airflow (Q) and the coefficients (A0-A3).

Curve

If you selected the Curve option, then the Fan Curve panel displays.

Enter the pressure (p) and starting airflow values (Q) for each point. Up to 10 points (with a minimum of 3) can be defined for the fan curve.

Fixed Pressure

If you selected the Fixed Pressure option, then the Fixed Pressure panel displays.

Enter the pressure value (p) for the fan.

Select Finish.

The fan is then added to the fan file.
