Dust Collector Fan Curve
Fan curves graphically depict fan performance data of cfm rpm sp and bhp.
Dust collector fan curve. A fan curve will show you how much cfm the dust collector will provide at any given static pressure which can be calculated base on what ducting hose is connected to the system. But that same table tells me at that big of an opening my horsepower will go way over for my budget motor that only has a real 3 hp. In reality proper pipe sizing can get complicated and depends on many variables. Tool size air requirements length of pipe run required number of machines running at one time etc.

I found the 8 5 and went across to the curve and then down to the axis and it says that my flow was about 950 cfm. Click here to learn more about sizing your ductwork. So using this information i looked at the performance curve for my dust collector.
Airflow performance through static ductwork. They are commonly used for ventilation forced cooling at higher pressures and on dust collectors where the fan is on the clean side of the collector. Available in models hdaf sqaf and cpaf blowers. Typically selected for general.
The donaldson torit backward inclined fan is a convenient and cost effective way to integrate a high efficiency fan with a high quality dust collector. The fan mounts directly to the clean air plenum of the dust collector eliminating costly transition ducting. Many dust collection systems suffer due to poor ductwork designs. Tbi fans are available in sizes ranging from 3hp to 30hp.
The ideal inlet for that 14 impeller is 10 from my fan table on the dust collection basics page. One of the popular dust collectors is the harbor freight 2 hp unit. Doing the same thing with the 10 3 the graph shows 625 cfm. I tested and found that with the leeson motor 14 diameter impeller and cyclone that i can use up to a 7.
Being able to read a fan curve will allow you to choose the best fan for your requirements as long as the fan is properly tested and certified.
