Doing the same thing with the 10 3 the graph shows 625 cfm.
Dust collector fan curve.
One of the popular dust collectors is the harbor freight 2 hp unit.
I tested and found that with the leeson motor 14 diameter impeller and cyclone that i can use up to a 7.
So using this information i looked at the performance curve for my dust collector.
Airflow performance through static ductwork.
Many dust collection systems suffer due to poor ductwork designs.
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.
Tbi fans are available in sizes ranging from 3hp to 30hp.
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.
Cincinnati fan 200s t1 portable dust collector 2 hp 3450 rpm 1 phase 115 208 230v tefc enclosure black gray white 4 0 out of 5 stars 1 1 335 51 1 335.
Fan curves graphically depict fan performance data of cfm rpm sp and bhp.
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.
The ideal inlet for that 14 impeller is 10 from my fan table on the dust collection basics page.
Type 7 forward curve multi vane blower wheels are for moving large volumes of air at lower pressures.
The first thing to note about the fan curve graph is that it has 3 axes.
The fan mounts directly to the clean air plenum of the dust collector eliminating costly transition ducting.
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.
Available in models hdaf sqaf and cpaf blowers.
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.
Typically selected for general.
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.
