As always with these things, it is important to keep in mind that there as some underlying physical restrictions. The static pressure (1750 Pa) doesn't tell you much, if that happens to drop to near zero as soon as any measurable flow starts. With a power of 1W, the theoretical maximum flow at that pressure is 1.21 CFM, but it is probably much lower in practice. In any case, it is meaningless to quote the pressure without the CFM.
