Typically each motor added to a bench will have less cfm vs your basic math example.
Example:
8 of the 115923 Ametek vacuum motors rated
well over 100 cfm each will only allow a 600 cfm rating at 25" water on a SF-600 bench.
600 cfm (280 l/s) @ 20" (50 cm) of water
500 cfm (235 l/s) @ 36" (90 cm) of water

I've put all the Domels info on a spreadsheet and compared the motors at 28", 60", 90" and there seems to be a good motor for the US market that could be better than the Amatek 115923 for high depressions
115923 10.8amp 103@28", 60.6@60", 11.5@90"
462.3.457-9 10.0amp 96.2@28", 69.2@60", 30.4@90"
multiply by 12 motors and the Domel is way ahead at 90" and is only a single

That's interesting! I wonder how the construction differs so that the Ametek drops for so much more between 60 and 90"

Actually Bruce, it is the Beer that is responsible for most of it.

There are a whole series of these large round plugs, with three, four, and five pins. All use the same round outer shell size, pin sizes, and pin centers, but they are keyed differently for different current ratings. Pins are easily removable, which is what most people do.
I have these fitted in my home workshop, garage, and my electronics lab.
