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 SPW-D253GH56 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 extention of duct, for example), the air flow volume may drop too low at each air
outlet.
