1. Shaded area represents selectable area.
2. Supply fan performance curve includes
internal resistance of rooftop. To
determine total static pressure, add
system external static pressure to
appropriate component static pressure
drops (evaporator coil, filters,
economizer, reheat coil, heating
system, final filters).
3. Motor horsepower offerings are
designated by horsepower lines shown
on fan performance map.
