IMPORTANT NOTES:
Sound levels are in dBA at 5' from the supply air opening. This figure does not account for attenuation,
additional noise or directivity factors. More horsepower required includes both the running horsepower and
the starting torque requirements. Horsepower can be greater than the standard fan curve charts. Brake
horsepower does not include drive losses. For external static pressure greater than 2", contact your local
representative or Rapid Engineering LLC. For operation in altitudes exceeding 2000' above sea level, contact
the factory. The recommended motor horsepowers shown for the Fan Selection Chart in the 0 in. wc external
static pressure column include fan and burner static pressures only (internal equipment static pressure).
Other cabinet options could add static pressure and should be included in the external static pressure used
to select motor horsepower. See the Static Pressure Drops in Table 20, Page 41 for the external static
pressu
res that should be added for selected options.
