I have no idea what the CFM requirement is on the HF 20 ton I put on mine but my gut tells me "not very much" and "it was a great addition".
I have air over hydraulic on both the engine hoist and the shop press. They both go "pht ... pht ... pht ... pht" when you apply the air. Obviously it is the air being released from the chamber with each stroke of the piston. I suspect that in a pinch I could run either of them to full extension several times with nothing more than a full portable air tank and no compressor at all.
I think I have the air lines regulated below 130 or less and I'm sure anything more than 80-90 will work. If nothing else it saves all the pumping to take up the slack and then you can go for the gold with just a couple of manual strokes.
In short, if your compressor can not keep up with the jack you may have trouble filling a tire with it.
But that is just my non-scientific opinion.

My non-scientific opinion concurs with arvidj's.

Thanks Arvid. I was hoping that would be the case. I'm going to get this compressor for now and upgrade later, if necessary.

With a "25% off one item" coupon floating around I thought I'd get the air over hydraulic jack. I have the winch coming this week also.

I wouldn't have thought that you would need to worry about CFM in this application, as you would not be running it continuesly. Air tools on the other hand are notoriously hungry and therefore specify necessary air supply. Nothing is more annoying than using a die grinder for 10 seconds and having it lag and the compressor kick on again.

And one of the key features of this compressor is that is has "Never-flat tires for maximum durability" so you never have to worry about its ability to fill a tire
