How to Read the Diagram
The vertical axis is the EXTERNAL STATIC PRESSURE (Pa) while the horizontal axis represents the AIR FLOW (m
3
/h).
The characteristic curve for the “H” and “L” fan speed control are shown. The name plate values are shown based of the
“H” air flow. Therefore in the case of the SPW-GU055XH the flow is 500 m
3
/h, while the EXTERNAL STATIC PRESSURE
is 183 Pa at “H” position (Air charge side). If the external static pressure is too low (due to short duct), the air flow volume
may be too great at each air outlet. To set the fan speed control to “L” position, use the supplied external static pressure
line switching connector. (Refer next page)
