Description
This fan speed controller is designed to be used with our ventilation fans which come in 10 cm and 15 cm depending on the size of your space and the amount of air you need to move. This controller will significantly lower the output of the fan, but also lower the noise floor as well. This unit goes between the power source and your fan assembly to enable you to adjust the amount of air passing through to your desired amount.
We measured the specs of the controller on our 15 cm fan assembly.
Here are the results.
With the speed at MAX, the dB measured 75 with a CFM of 204.
At the MED speed, the db was 57 with a CFM of 80.6.
When set at the LOW, the dB was 51 at 52.98 CFM.
At it’s lowest speed setting the dB was 48 with a CFM 35.33.
