I might just add ...
I am a bit clearer on the different higher power versions of the Electro 5.7 available to the UK now .
Ashbys high power motor is a flat bottom 1600w - model 6600-49 .
It produces 560 airwatts ( 148" lift and 110cfm ) 7.1 amps max
The next version is also around 1600w but it had a conical bottom . It is model 6600-47-A-MP
It produces 585 airwatts ( 154" lift and 110 cfm ) 7 amps max .
It kind of needs a special gasket which electro supplies into which it sits .
They also supply a flange tube adapter if you want to connect straight to a hose
It would have to be explained to me why Ashbys and others dont use this version insted of the flat bottom version . ( i would say its because the flat motor likely costs a bit less )
I picked up a 6600-47 , this is what it looks like .

It is a conical bottom like above ... but the motor is about 1800w 640 airwatts
Lift is 152 cfm is 117 - 8.6 amps max
Not suitable for two vacs on one cord but this is the one i would put into the Airflex pro with a two cord conversion .
Im told you can order any of the above from
j.brown@maltonplastics.com a supplier of sort in the UK for Electro i think , state the model number you want or you will both get confused .
