How much CFM would this thing consume?

It doesn't "consume" any. You use a tire chuck to pressurize it, then use the blow gun to release the pressure and liquid into the system
I have the exact same one. Works great.How much CFM would this thing consume?

Do you use it to inject a cleaning solution ?
If the is debris inside the system where does it go ?

That one looks like you pressurize the can, like a sure shot sprayer. Shouldn't take much CFM at all. I have this one and you leave the air hose hooked up to the can while using, https://www.amazon.com/dp/B0FSZ3WPZ9?tag=atomicindus08-20. I use it a few times a year to flush the lines and the evaporator when I change a compressor, condenser, dryer, and expansion valve. Be aware that a quart of flush goes really fast. I usually go through about 2-3 quarts flushing just the lines and evaporator.How much CFM would this thing consume?
Yes it flushes the system when changing components so you will have the system opened up. The evaporator is just like flushing a heater core, in one side and out the other. When flushing the hoses both ends are disconnected so it goes in one end and comes out the other. The flushing fluid is some chemicals(expensive) that are supposed to break down the oils and flush out any debris that may be in the system, usually when a compressor goes bad. Can't flush the condenser because it has a bunch of very tiny channels so I just replace it every time I do a compressor. Not sure how good it does on evaporator if metal gets in there but those are usually a big job to replace so I just flush the best I can and hope for the best.
Denatured alcohol is what I have used in the past. Boating stores stock this stuff since it is used in boat stoves.

Aren't the passages about the same size on both the condenser and evaporator ?

I've read that before and started to look into it a little more but haven't had time. I've seen a couple people say they tried denatured alcohol and it came out almost as clear as when it went in but when they used the actual flush chemical on the same system after the denatured alcohol it came out black. Something about the chemical in the flush being able to break down the oil in the system and mix with it to get all the stuff out. I need to look into it some more because a quick check shows menards sells DA for 15 bucks a gallon and easy to get. I did see the other week if I was to order the actual flush chemical in a gallon from autozone it would be 55 bucks for the gallon vs 25-30 per quart.

Yes but there is a filter/dryer between the condenser and evaporator which hopefully catches most of the debris. Also the condenser is usually an hour or so to replace vs the evaporator that requires removing the whole dash in most vehicles. So I do the best I can to clean the system and insure new compressor doesn't get contaminated without the repair getting stupid. I know you have complained about repairs being too expensive like the struts and other posts of yours, I can just imagen if you needed a compressor and the shop quoted you an extra 1500-2000 to replace the evaporator on top of the cost of the compressor job to make sure there was no crud leftover in the system. It's a matter of doing the best you can but still being reasonable.
