Understanding the Performance Curve

  • The blue curve is the fan's performance curve. In this example it is shown speed controlled down to 87.5% of the fans full speed.
  • The magenta curve is the system characteristic based upon your entered design duty.
  • The green dot is the design duty and the yellow dot the design duty adjusted for selected ancillaries.
  • The red dot is the operating point for this fan when running at full speed.
  • The grey bar highlights the acceptable margin you specified either side of your required duty point.

If you select an ancillary that causes a resistance, such as a podded attenuator, the performance curve is altered:
  • The grey curve is the resistance of any selected ancillaries.
  • The yellow dot is your design duty adjusted for the resistance of any selected ancillaries.
  • The purple curve is the adjusted system characteristic based upon the adjusted design duty.
  • The dashed red curve is the original system characteristic.
For fans that can be speed controlled the overall performance envelope of the unit is shown in shades of blue. These shades of blue represent increasing amount of Specific Fan Power with the lightest being upto 0.5 W/l/s.
