SSeries Fan Curves
The fan curves illustrated to the right show the range of capacities available
for P-Series direct drive units. Each graph shows the performance of several
models at one particular nominal speed. Fan curves provide a quick method for
selecting a fan unit based on design point requirements.
The direct drive performance charts provide the tabular data (CFM and
static pressure) used to plot the fan curves. In addition, horsepower, tip
speed and sones are tabulated.
Sinces sound is normally an important factor in
the selection of a fan, an engineer will usually want to select the “slowest” unit
which meets CFM and SP requirements. Please refer to the Motor Selection
section to make sure the motor you select meets your electrical requirements.
