re: Koenders. I found out earlier this year that their windmills and compressors furnish 1.1 cfm of air, and it's only the newest ones that furnish double that amount of air. Since their model numbers haven't changed, I don't know how to tell what specific compressor furnishes the greater volume of air.
Esshup,
I could be wrong, but I think it is their "double diaphragm" units that make double the CFM. I have one of the double diaphragm units. It still does not make a plume any where near the size of the plume the American Eagle makes. I know that isn't very scientific and I do not have a way to measure the CFM produced by either unit, but you can clearly see a difference.
Good luck with your shoveling..... I hope you find the leak in the first foot and not the 590th foot!! lol
