Rpm normal ceiling fan. What is the rpm of a normal ceiling fan. If you have high ceilings operate the ceiling fan at its lowest possible speed to bring the warm air trapped at the ceiling down to occupant level. Airflow delivered by a ceiling fan is the rpm of the fan measured in cmm cubic meters per minute.

The rpm stands for rotations per minute and refers to the number of times the fans make a full rotation every minute. Wind speed is calculated by measuring how quickly on average air can get from the ceiling fan blades down to the floor and is commonly reported in miles per hour mph. The bigger the blade size the more airflow. Ul actually states the limitations based on the maximum allowed speed of the tip of the fan blade at 3200 feet minute for 3 16 thick blades and 2400 feet minute for 1 8 thick blades.

If your fan can run slowly enough to not create a breeze at its lowest speed setting it is most efficient and most effective to operate the fan in its forward position blowing downward. 350 rpm for normal fan with 75 watts.

An instrument called an anemometer is used to calculate the wind speed by placing it in the direct flow of the wind allowing the propeller or cups to spin through the wind.
