The net capacity data has fan motor heat factored in for all ratings and the entering air conditions of 75°F (23.9 °C), 45%RH, is the
standard rating condition for ASHRAE 127-2007. All capacities are nominal values; actual performance will be ± 5%.
* DME027 has two motors - 0.08 & 0.12 HP; ** DME037 has two motors - 0.11 & 0.16 HP
