Using Higher Voltage for More Airflow with an Electric Fan

Flex-a-lite Syclone S-Blade Electric FanWe often get asked if using a higher voltage battery increase the airflow of an electric fan. The answer is yes!

Racers and audio enthusiasts were the first to use 16-volt battery for better ignition and audio performance, and they are becoming more popular. An electrical-system expert will tell you that a small variation in operating voltage will raise or lower the speed of an electric fan, which increases or decreases the airflow. For example, Flex-a-lite's part number 398 electric fan (16-inch Syclone S-blade fan) moves 2,500CFM in a 12-volt system, but increases to 2,700CFM in a 16-volt system.

The additional airflow from the fan does have a cost to the motor. The increase in fan speed and heat caused by running in a 16-volt system will result in a slight reduction in fan-motor life. Flex-a-lite motors are rated for over 5,000 continuous hours, so most applications will not be affected by this slight reduction in motor life.
