CEILING FAN PERFORMANCE GUIDE
Throughout the catalogue, you will see detailed fan specifications with the table below included. This example is a quick
guide to explain what each of the measures mean, and how to spot a fan with the right specifications for you.
AIRFLOW is measured in Cubic Feet per Minute (CFM). The higher
the airflow number, the more the air the fan is circulating.

Cubic ft. per minute on high
POWER USAGE for your fan motor is measured in watts. The lower
the watts, the less energy the fan consumes. DC motor ceiling fans
are the most energy-efficient, using the least amount of wattage.

AIRFLOW EFFICIENCY gives you the total picture: dividing the
fan’s CFMs by the watts of power it consumes. The higher the airflow
efficiency number, the more air the fan is moving per watt.
