I am looking into buying a cyclone and have narrowed it down to 2. One fan curve is almost flat, while the second is much higher at low static pressures and much lower at high static pressures. The second vender says the sharply sloping curve is more appropriate, as 15' of 4" hose hooked to a jointer will be about 4" of static pressure. Based on what I have read in the past, I would have expected it to be more like 8 or 9", and the flat curve is much better there. So, the superior unit depends on how much static pressure I will be seeing. Can anyone point me to documentation on this?
Static pressure with 15' of 4" hose on a cyclone?

Depends on whether you're talking flex hose or straight wall pipe/hose. 4" sounds about right for smooth wall, 8-9" for flex hose of that length.
Unless you have a fixed path and distance, it'll vary anyway as you move the hose. If it is fixed location, I'd recommend ditching the flex hose for anything except the shortest run possible as connection, maybe.
