How to Read the Diagram
The vertical axis is the EXTERNAL STATIC PRESSURE (mmAq) while the horizontal axis represents the AIR
FLOW (m
3 /minute). The characteristic curve for the “H”, “Med”, and “Lo” fan speed control.
The name plate values are shown based on the “H” air flow. Therefore in the case of the 25 type the flow is 23 m 3 /
minute, while the EXTERNAL STATIC PRESSURE is 19 mmAq at “H” position. If the external static pressure is too
great (due to long extension of duct, for example), the air flow volume may drop too low at each air outlet.
