System Curve and Fan Curve

To reduce air flow from Q1 to Q2
Thus, reducing the fan speed is a much more efficient method to decrease airflow since less power is required and less energy is consumed.


Fan Characteristics

  • The intersection of the system curve and the static pressure curve defines the operating point.
  • ¬†When the system resistance changes, the operating point also changes.
  • Once the operating point is fixed, the power(BHP) required could be found.
