How to Read the Diagram
The vertical axis is the External Static Pressure (in.WG) while the horizontal axis represents the
Air Flow (CFM). The characteristic curve for the “H,” “Med, ” and “Lo ” fan speed control.
The nameplate values are shown based on the “H ” air flow. Therefore in the case of 36 Type, the
flow is 1059 CFM , while the External Static Pressure is 0.72 in.WG 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.
