How to Read the Diagram
The vertical axis is the external static pressure (Pa)
while the horizontal axis represents the AIR FLOW
3
(m /minute). The characteristic curves for "HT", "H",
"M" and "L" fan speed control are shown.
The nameplate values are shown based on the "H" air
flow. If 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.
This problem may be solved by increasing the fan
speed as explained on the previous page.
