EC Motor Operating Range and Core Performance

This section presents the operating characteristics of the EC motor. A graph illustrates the relationship between Airflow (CFM) on the horizontal axis and External Static Pressure (ESP in. H2O) on the vertical axis, showing performance across a range of airflow from 0 to 140 CFM and ESP from 0 to 1.8 in. H2O. Two data sets are shown: "Actual tested sample points" (dots) and "Operating curves" where airflow is held constant as static pressure varies.

Factory Settings

• 1. High speed set to top curve.
• 2. Low speed set to ~90CFM at 0.4 in. w.g. ESP.

Notes:

1. Watts is for the entire unit.
2. Airflow performance includes effect of clean, standard filter supplied with unit.
3. Refer to CORES for specific operating point electrical data.
4. These are core-only ratings and are not HVI certified. Total EFF% calculated at 35/33wb OA and 70/58wb RA (winter) and 95/78wb OA and 75/63wb RA (summer). HVI ratings apply to complete units only. This unit is HVI certified. See HVI certified ratings on pg. 46 of Single/Multi-Family Catalog and at hvi.org.
