1. Values include losses for filters, unit casing, and wet coils. See this
page for accessory/FIOP static pressure information.
2. Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using fan
motors up to the wattage ratings shown will not result in nuisance
tripping or premature motor failure. Unit warranty will not be
