W6SAI ran an excellent article on blowers many years ago in CQ Jay. It
compared speed and wheel diameter vs backpressure and the whole bit. When
you go by the industrial manufacturers specs, there is no fudging. I am
talking about blowers, not muffin fans.
I can pbly dig that article up out of the files for you and others for a
large SASE.
