As an online consumer, it is important for you to understand what it is you are buying before you purchase, because you don't have the ability to actually look at the product and see it function. Some manufacturers would like you to believe you are buying something you are not. As an example, you may think you are buying a fan rated at 500 CFM (cubic foot per minute), but in reality you are getting a unit rated only 210 CFM. Be sure you know the "Free Air" ratings of your duct fan before you make an online purchase.
"Free Air" is a rating given to a fan that is not installed in a duct line. There is no restriction to airflow or static pressure. (This is the rating you would get if you simply have the fan plugged in and sitting on a table in front of you.) "Boosted Air" is a rating given to a fan as a maximum number of CFM's the duct fan will push before it becomes a restriction itself. It does not mean you will even come close to this "Boosted" number and it is based on a certain number of CFM's pushing on the back end of the duct fan from your main blower to help the duct fan generate more RPM's, - thus more CFM's.
Chances are if you are having airflow problems to begin with you are not going to have a lot of CFM's pushing on the back end of your duct fan - let alone enough to even get you close to the "Boosted Air" rating you thought you were going to get. "Free air" is really the only fair way to rate these Duct Fans due to the amount of variables within each setup, such as duct length, 90 or 45 degree bends, how many CFM's are pushing on the back end from your main blower, and where you plan to install your duct fan.
