|Revolution Speed (RPM - Revolutions per Minute)||Air Flow (CFM - Cubic Feet of Air Flow per Minute)||Electricity (Watts - Electricity used not including any Lights)||Efficiency (CFM/Watt - Cubic Feet of Air Flow per Minute per Watt used - higher is better)||AMPs (Amperage of Electrical Current used)|
|Efficiency is the cubic feet of air that can be moved in one minute if the fan were to use 1 watt of electricity, and can be used to compare energy-efficiency among different ceiling fans. The higher this number the more energy-efficient the fan is. This ceiling fan's airflow efficiency is below average, compared to fans with a 52" blade span. By comparison, other regular-sized ceiling fans with a 52" blade span typically provide an airflow efficiency ranging from 71 to 100 cubic feet per minute per watt.|
The electrician put it in and it works great on medium speed. It cools the room off and it is silent so I can sleep.
