    Hello! New to airbrushing here, I'im trying to get everything set up to start for the first time, but I seem to be getting a little confused....


    I am purchasing the California air tools compressor that is recommended a lot in this forum https://www.amazon.com/dp/B00NOSCDPA/ref=cm_sw_r_sms_c_api_GtVRybTWWXBNB

    I have an iwata eclipse hp-bcs. Since I live in Florida I want to take care of the humidity factor as much as I can and would like a regular with a water trap added to the compressor and possibly another water trap added to the gun or the line after that. I also need to make sure I have all the adapters/couplers to get the airbrush connected to the compressor properly. The picture I see posted a lot with the adapters is a little confusing to me so I haven't made much headway there... I am trying to spent enough to get quality items but I don't want to overpay just for brand name stuff that is just as good as generic either.

    So my questions are:

    -which adapters/couplers do I need for completing my set up?

    -what parts are better to get through iwata or is there another better, most cost effective brand or is generic easily the best choice? (Example: get iwata quick connect coupler Iwata-Medea Quick Disconnect Set https://www.amazon.com/dp/B001P5S5CO/ref=cm_sw_r_cp_api_tBVRybWCM2H4D or any brand is fine...

    or get the zero point regulator as opposed to iwata:

    https://www.amazon.com/dp/B004KNAHE2/ref=cm_sw_r_sms_c_api_jAVRybQMZ2NNV )

    -is there a better place to buy the parts that don't need to be iwata? Any preferences?


    Thank you all in advance for any help!

    Hi there, the search function is really useful for this. There is already plenty of discussion along these lines. Here is one thread for a starter
    http://www.airbrushforum.org/threads/what-hose-connector-do-i-need.17082/#post-256094

    As a newbie it's always good to introduce yourself properly. Can I get you to pop along to the intro section and say Hi? How did you get into airbrush, what do you want to paint, where you live (Florida... :) ) Here is that link.

    They both look good. I would stick to the Iwata quick connection however they do ware out over time. You most likely will not need a second moisture trap in line with a tank system. Most of the moisture will collect in the air tank so make sure to drain it at the end of every session. The only time you will need an additional one at the brush is if you are running a long hose before the airbrushing hose. You might need a half inch to quarter inch adapter for connecting the hose or regulator to the compressor, but I am not positive on that. There are tons of other things that very with what you will be painting. One thing for certain is a reservoir for flushing the airbrush into when changing colors. Also some bottles with fast blast type lids for quick color changes. Spare nozzles and needles for the fist time you crash and burn.

    If your picking up the compressor and have the airbrush hose bring it with you and ask them to get you the right connections to do it.,If your getting it delivered to your house just bring it in to the hardware store and have them do it,That way you get the right fittings and will have less air leaks that way

    I run an air line from my compressor to a filter/regulator, then to the airbrush hose.
    The air lines should all be 1/4" npt, so no adapters would be required, except possibly a male/male or female/female adapter. The airbrush hose will be 1/4" npt on one end and 1/8" on the other, all of which can be connected without quick disconnects, if you want.
    I'd you use QD's, the Devillbiss hi-flow 1/4" are my favorite. Five years of shop use, and I've never had to replace one yet. The hardware store QD's will work, but tend to have slight leaks and wear out.
    For the airbrush QD, I use a Grex G-Mac. The Iwata ones work great, too. The off-brand stuff I've had less than great luck with.

    For the filter/regulator, there's no need to break the bank. Any hardware store or even most of the Harbor Freight ones will work just fine. An airbrush doesn't use much air, so the filters have more time and are more effective than if you were running a d/a sander. You can add a dessicant style filter if you want to make sure your air is really dry.

    The Iwata filters that attach to the airbrush are nice, but mostly because you get a comfortable grip. I have them on all my airbrushes just for the easier grip, but I've yet to see a drop of moisture in any of them. So, pretty much completely optional. Or cheap insurance...

    Hope that helps a bit

    Only reason I mentioned a 1/2" to 1/4" adapter is some construction type compressors use 1/2 in connection, but you should check the specifications for what you intend to buy so you don't get unnecessary items. Also some teflon tape should be used on the threads. I have put my regulator and moisture trap at the end of the main hose before but found that the build of moisture in the main supply hose will gunk it up over time. That is the only reason I suggest one at the compressor and one before the airbrush hose but only if you are using a long supply hose ( more than 25'). This is all based on my own personal experience.

    Thank you everyone for your replies! This has helped me a lot...

    I think I'm going to get the iwata quick disconnect just to be sure and run the filter/water trap right on the compressor before the hose and see how it does ... I'm going to get the compressor delivered so I'll wait to check what adapter it would need at that point!
