Dust Collector Fan Curve

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.

Dust collector fan curve.

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. Doing the same thing with the 10 3 the graph shows 625 cfm. The fan mounts directly to the clean air plenum of the dust collector eliminating costly transition ducting.

The first thing to note about the fan curve graph is that it has 3 axes. 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. One of the popular dust collectors is the harbor freight 2 hp unit. Fan curves graphically depict fan performance data of cfm rpm sp and bhp.

Tool size air requirements length of pipe run required number of machines running at one time etc. 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. So using this information i looked at the performance curve for my dust collector. 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. There is a large amount of misinformation about what the proper size pipe is to run. Type 7 forward curve multi vane blower wheels are for moving large volumes of air at lower pressures. Many dust collection systems suffer due to poor ductwork designs.

Available in models hdaf sqaf and cpaf blowers. 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. Typically selected for general. Tbi fans are available in sizes ranging from 3hp to 30hp.

In reality proper pipe sizing can get complicated and depends on many variables.
