Need to not go and play starcraft for days at a time lol... It depends on the compressor itself. The ones I use are primarily meant for pumping up car tires and running air tools (like Air nailers for building a house). I've never exceeded the pressure limit for my airbrush by more than 15 psi because my compressor has a regulator on it that allows me to limit how much pressure comes out of it. I assume it could do damage if it was too much for too long, or it could just screw with how nice the paint flow is (which was listed as an issue to trouble shoot on one of my old air brushes). Do you know what the pressure is coming out of it (tire compressors normally are high because it needs to get the tire up to pressure while having a lot of weight on it)? that airbrush has a really big range 20-55 with a 75 max so its a pretty tough brush but yeah things can go wrong after 75. That said because it is a tire compressor, it very easily could get condensation in it, the lazy way of dealing with it is the 100 foot hose (which I got because it was the same price as the 20 foot hose - go figure). You can also use the drain which should be built into the bottom of the tank (if there isn't one then you don't really have an issue it's been built to deal with said condensation in the motor/pipes themselves) it blasts the air and condensation out when you pull it. I only see condensation if I am running long projects on it and then it only make s it to the first 'catcher' for the most part thought it's likely safe to say that the hose does get a little of it.
