NOTES:
1. Units are available with several motor hp options. Refer to Table 1.
2. Static pressure losses for any options or accessories must be
applied to external static pressure before entering the fan perfor-
mance table.
3. Interpolation is permitted; extrapolation is not.
4. Fan performance is based on 1 in. standard throwaway filter, unit
casing, and wet DX (direct expansion) coil losses at sea level.
