The Speed Control is a must have with any size High-Velocity inline fan to dial in those temps, vent the exact amount of air you need or to greatly reduce the wind noise of your fan. This speed control will reduce the wear on you inline fans and extend the life when the full air flow is not needed and will quiet your fan at the same time!! When used in conjunction with a fan and filter combo it will extend the life of your carbon filter if you do not need the full air flow. Turn the speed down to low in the winter months when full ventilation is not needed and turn to full speed in the summer months when things start to heat up. Using the Airspeed control you can actually get 1 size larger fan and turn it down getting the CFM flow you need. Getting a larger fan and running at the low to medium speed will actually get you the same airflow of the smaller fan but with much less noise.
