I hear people say EDF's are not a 'Compressor'... but just a pump.
How can something that speeds up air flow, and feeds that into stationary air, NOT get back pressure... and thus increase pressure... like a Compressor?
It must.

It may not be DESIGNED to mimic what a jet engine compressor compresses air down to... but it still does compress it.
And this air compression... density.... must come into play in the output... the maths... of it all...

CFM doesn't state what density the fluid had. It tends to just be a measure of "you moved this much of that item" and assumes the item was the same.
But denser air is not the same as less dense air....
