|The truth about "Free Air" and "Boosted Air" Ratings!
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 before
hand. There are some manufactures out there who would like you to believe your buying something you
are not. As an example you may think you are buying a 500 CFM rated fan but in reality you are getting
maybe around a 210. Be sure you know the "Free Air" ratings of your duct fan before you purchase. We
explain a little more in detail below.
"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 in
order to help the duct fan generate more rpms thus more CFM's.
Chances are if you are having airflow problems to begin with you are not going to have alot 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 like 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.

What is an Inline Duct Fan?
You may hear it referred to in the following terms: Duct Fan,Inline Duct Fan,Air Booster Fan,heat duct fan, etc.
It is used primarily to help move warm or cold air throughout your home utilizing existing or planned ductwork.
What are CFM's?
CFM stands for Cubic Feet Per Minute and in this application it is defined as a rate of airflow. Most CFM
ratings are measured in a controlled environment persuant to specific industry standards. Higher CFM ratings
do not always mean a stronger fan it simply means there is more space for the air to flow through. If you see a
240 CFM 6" Fan and compare it to a 1350 CFM 14" you think automatically the 14" is much more powerful unit
when in fact it moves at about the same RPM and reacts to restriction in much the same way as a 6 inch unit
does. The fact the 14" unit has 14 inches of free air space is the main reason it has a much higher CFM rating.
