I am looking to use a 5-gallon Craftsman portable air tank for airbrush use to avoid moving large garage compressor around. Was reading that some regulator/moisture control units bleed out portable tanks too fast. Was looking at the Paasche R-75 regulator and moisture trap set up on Amazon but concerned it will bleed out my portable tank. New to airbrushing. Thanks
Mine is from Speedaire. I bought it from Grainger.

I am completely happy with it.

Living the dream.
If the Regulator is set to flow at 15psi, would it only let that volume of air at 15psi pass at the nozzel and only when the airbrush is in use? If you have a before the brush tiny bleeder hole then your portable/compressorless tank will bleed down while not using the brush.
Without knowing where and how the brush end will be used, (train room, outside, special paint room) is there any chance you could run an air hose or pipe (above ceilings around floors, under ground around the house, one and done) from the garage compressor to the location where you are doing the paint work? Then you'd have endless air and never have to recharge the portable tank.
EDIT: Now I think I remember about that little bleeder hole in that 1/4'' x airbrush hose size brass fitting, it was used with the Badger spare tire adaptor (no regulator, just a screw to close down, just very low air flow) dad wondered why the tires on the car would loose air, so that bleeder hole would not let the brush pressure build up to the pressure in the tire. You would not get 40 lbs. of air out of the brush at first before it dropped down to your, ''close the screw for lower setting'', for paint flow. Maybe 45 years ago I drilled out and tapped that hole and put a tiny brass screw in it, so no bleed down/leak at this time.
The air compresor will produce 100-150 PSI of pressure.
There is no such thing as an air compressor that is too big for an airbrush, you just need a regulator.
The regulator will reduce this to whatever you select. It does not leak or bleed off air. It is a differential valve where you can adjust the spring pressure. The regulator does not limit flow, just pressure. Regulators do have a maximum flow they can pass, but I have never encountered one that flowed too little volume for an airbrush.
Yes, you can plumb your whole house with compressed air if you like. I just have a 1/2" pipe going through the garage wall into the train room.
I have a 200PSI\15Gal compressor. I can heat up the garage quite quickly and airbrush out there or if I have to do track or something else on the layout in the trainroom I just run a hose in from the garage. I have one of those 5 Gal portable tanks and they are a hassle. I would much rather run a hose into the house than lug that thing in and out. My compressor hose is on a reel so it is easy to run it to the trainroom and wind it back up when I am done.

Thanks, what confused me was a comment a buyer posted about the Paasche regulator/moisture setup stating it constantly bleed air. Does seem odd to me that it would bleed air since I have used larger moisture traps and regulators on garage size setups that don’t.
I bought a look alike on Amazon. It did not bleed until it developed an internal leak after a couple months. Then it was worthless as it was a major leak.

If there is concern about bleed, a cheap, simple, in-line valve will solve that-local auto supply store.

Wanted to follow up. Purchased the Paasche R-75 regulator and plumbed it to a quick connect fitting to connect to my portable 10-gallon 135 psi tank. It works just like it should. No issues, no leaks. Thanks for the info.
WPA It works just like it should. No issues, no leaks.
I am glad to hear you are up and running. That is welcome news.
