Performance
Data
Heating performance is based on 70 F (21 C) entering air temperature, 2 psig
(14 kPa) and 5 psig (103 kPa) entering steam pressure.
All performance measured on high speed tap, 115 V, 0.2" (.5 cm) ESP , with no filter.

Note:
1. Medium and low speed capacities are approximately 80 percent and 60 percent respectively of the high speed capacity.
2. Q/ITD = MBH (kW)/(Saturated steam temperature - Entering air temperature). To determine heating capacities at different
entering steam pressure or entering air temperature, compute the new ITD and multiply it by the Q/ITD shown. (See the Steam
Properties table at the end of this section to determine the saturated steam temperatures at various entering steam pressures.)
3. High static motors need the appropriate length of duct to prevent poor acoustical applications.
