How to Read Diagram
Œ
The vertical axis is the external static pressure(mmAq) while
the horizontal axis represents the AIR FLOW(m3/min).
´
The characteristic curves for ‘HH’, ‘H’, ‘Med’, and ‘Low’ fan
speed controller are shown.
ˇ
The nameplate values are shown based on the ‘H’ air flow.
¨
If external static pressure is too great, the air flow volume
may drop too low as explained above.
HH : DIP Switch OFF position(High speed)
H : At shipment(Normal speed)
