Wood and Metalworking Machine Basics Editorial Product Review

Many woodworkers setting up a shop have asked us for detailed infomation concerning air flow curves and a Static Pressure Testing on dust collectors. JET Equipment & Tools has been nice enough to supply us this information. I would be glad to also add other companies testing information if it is detailed and included curves and charts.

JET Dust Collector Factory Test Procedures

THE METHOD FOR TESTING FLOW CURVES

1. Test the Air Flow (cfm/m3/min) and the Static Pressure (in-H2O) with different diameters (hose size) of the intake.

2. According to the size of the intake (hose size) choose the plate with the right caliber for testing.

3. Change the caliber from small to full open and test the CFM and Static Pressure (in-H2O).

4. Record the CFM and the Static Pressure ( in-H2O) from the above test for 6 various calibers (diameters) and mark them on the coordinate (X;in-H2O; Y: CFM). Then draw a curve from those 6 points.

 

THE METHOD FOR TESTING STATIC PRESSURE

Block the intake and reduce the Air Flow to zero, then take away full pressure probe and leave the static pressure probe. This will give a reading of Max. Static Pressure.
