Performance Curves

Fan Performance Curves

This graph illustrates the relationship between external static pressure and airflow volume for different fan speeds.

X-axis: External Static Pressure (InWg)
Y-axis: Air Flow Volume (CFM)
Lines: Representing Super high speed, High speed, Middle speed, and Low speed. Airflow decreases as static pressure increases for all speeds.

Cooling Performance

This graph shows the cooling capacity in BTU/H relative to the outdoor dry bulb temperature in °F.

X-axis: Outdoor dry bulb temperature (°F)
Y-axis: Capacity/BTU
The graph indicates that cooling capacity increases as the outdoor temperature rises from 68°F to 113°F.

Heating Performance

This graph displays the heating capacity in BTU/H relative to the outdoor dry bulb temperature in °F.

X-axis: Outdoor dry bulb temperature (°F)
Y-axis: Capacity/BTU
The graph shows that heating capacity increases as the outdoor temperature rises from 14°F to 50°F.
