Sets a constant CFM by adjusting the RPM to conform with the Unico System fan curve

11. Fan Curve Uses up to 45% less energy Much slower RPM Air Handler Much Quieter In the following Slide we have – 1250 CFM at 1400 RPM (MAX) – 488 watts of power consumption – See additional speeds for Stage 1 and Fan

12. Blower Curve 1. 1250 cfm 1.2” w.c. 488 watts (Y2) 2. 625 cfm 1.2” w.c. 210 watts (G) 3. 700 cfm 1.56” w.c. 280 watts (Y1)
