oh you are gonna have some fun with this. Compressed air should work fine as long as your compressor can deliver the flow required by your machine. The small miller i used required 4.5 cfm at 60psi. As for nitrogen, i wouldn't recommend it. Most people run nitrogen because they don't have a source of compressed air or think that it is cheaper then buying a compressor, but by the time you get the bottle and all the fittings you are only a few bottle fills away from the cost of the compressor. As for a filter dryer,i would check the documentation of the one you got but the last one that i used did not have a dryer and seemed to work just fine. If you live in a very humid environment i would get one anyway as long as it doesn't interfere with your required flow.
