For three phase motors, substitute “*” with “M” for 230/460 volt or “P” for 575 volt. If 208V is required please specify. dBA ratings shown are measured at 0” static pressure and should be used as a guideline only. + Motor RPM is 3450. All others are 1750. Fan tested in accordance with AMCA Standard 210 in a figure 12A configuration. FEP for models using a single-phase motor are determined using AMCA Standard 214-21, method 6.3 using standard air density and V-belt drive. FEP for models using a three-phase motor are determined using AMCA Standard 214-21, method 6.4 using standard air density, V-belt drive, 4 pole TEFC motors without VFD. Power rating does not include transmission losses. Performance ratings do not include the effects of appurtenances. Operation of the axial impeller in a configuration different from the published test configuration will affect performance.
