Determining Main Line Duct Diameter
The general rule of thumb for a main line duct is that the velocity of the airflow must not fall below 3500 FPM.
For small/medium sized shops, using the inlet size of the dust collector as the main line duct size will usually keep the air velocity above 3500 FPM and, depending on the system, will allow you to keep multiple branches open at one time.
For the Model G0442/G0601 this is 8" with the reducer installed. Mark your drawing as in Figure 50.
