Performance Data Notes:

1.Nominal air quantity based on 90 fpm velocity and the module’s gross face area.

2.All fan motors are 1/3 hp single phase; 1570 rpm at 115, 230 and 227V 60Hz, and 1310 rpm at 230V 50Hz. Full load amps: 2.4 at 115V; .94 at 230V and 277V, 60Hz.

3.Based at 80% of nominal air quantity.

4. Weights: 24x48: Std.= 66 lbs, RSR = 92 lbs.
