excuse for butting in, but can't you just power up for maximum flow 
and pressure then throttle either the intake or exhaust air for 
current control.  The motor only draws enough current to move the air 
at the required volume and pressure which is determined by the orfice 
that the air has to pass through and can be mechanically controlled.
