I've got a related Q:
I've been looking for another blower, because the one I picked up was too large, with a motor protruding quite extensively.
So I recently came across this:
http://www.allelectronics.com/cgi-bi...171&type=store
It's a Comair Rotron, with the same leads, but no stats. From the power draw, I can only assume that it's not rated as high as I want it.
Also, it doesn't match any other blower, from the Comair Rotron website, except in dimensions:
http://www.comairrotron.com/pdfs/DD4021Series.PDF (PDF 2 pages).
I'm a little puzzled. 4" would be perfect, but if that blower draws .25 amps, then it's only 3 Watts. If it's a typo, then it would be 1.25 amps, which would make a lot more sense, and match almost perfectly the stats for the first blower on that spec sheet.
Also, the pressure measurement is in "Ps", which I can't reconcile: is it Pascal, or psi, or something else?
If it's a Pascal, then it's equivalent in centimeters of water, is 0.01, which is awfully low.
If it's psi, then it's equivalent in centimeters of water, is 77, which is awfully high.
