I disagree, I've been pretty sure for a while the active compression control is just a small 1/2 hp or 1hp Variable frequency drive like the ones Wolf Automation sells. Scott always cleverly dodges my comments when I mention VFD's. All that would have to be done is adjust the VFD based on pressure/vacuum in the concentrator line.
HVO seems to think they are not needed, and they certainly get good results without it. I'm with mute, an adjustable check valve does the same thing and analog is always more dependable.
