Hi Michael,
There was not any scientific calculations involved with my decision.? I had 4- and 5-inch hoses, so I designed my DC pipe around these parameters.? My KF 700 SP is the first machine in the DC pipe run from a ClearVue CV1800.? The main pipe from the cyclone is 6-inch.? It is quite adequate for a 2-car garage shop and 1 woodworker, who only turns on one machine at any given time.? With the 4-inch hose for the over head saw guard, there is enough air flow to carry small cut offs up the hood and to the cyclone impeller.??
