However, I do know that pressure regulators are prone to break over time. Operating an airbrush without the ability to regulate the air pressure will be very difficult, especially when trying to airbrush fine detail. First of all, it is typically best to place your air pressure regulator before the moisture trap. However, do keep in mind, by placing the pressure regulator down the air line away from the air compressor you will be putting greater amounts of stress on the air line up until the regulator due to the extensive amount of pressure in the air line.
This means you will need to buy a quality shop air hose that can handle high air pressure over an extensive period of time. The second place you can put your pressure regulator is just after the air compressor and before the shop air hose. This will likely put less stress on your air line, due to the lower psi that will be flowing through it. To which will likely be the best option in my opinion if your gonna need both.
Likely the most asked about part in regards to connecting an airbrush to an air compressor are the connections that are required in order to do so. Well, under most circumstances the common air compressor connectors and couplers will do just fine throughout the majority of the air line. But the cool thing is, is that, a majority of the different airbrush hose is available will come with an adapter that will easily thread on to your common shop air hose connector.
The airline layout that I am currently utilizing requires 3 couplers and 3 plugs. However, depending on your requirements you may need more or less, it all just depends upon the setup to which you are trying to build, and the distance you need to fill between your compressor and your airbrush work space.
But keep in mind this is an optional part of the line, as it will depend on the placement of your compressor, and the placement of your workspace.
If your compressor is located some distance away from the space you intend to airbrush in. The compressor I personally use is small enough I can move it around where I need it, without it being to much of a hassle. So most of the time I remove the Shop Air Hose from my air line. But your situation, may be different. Simply because the majority of Airbrush specific air hoses are not long enough to fill the gap and leave enough slack to give you free mobility with your airbrush.
Most airbrush air hoses are between 5 — 10 feet in length. Moisture in the air line can be a big issue, especially if you are trying to airbrush on something of high value…. Known commonly as a moisture trap, or oil trap. This rapid change in air temp will create small water droplets. And over time as this process happens over and over again, those small moisture droplets will begin to build up, and soon make their way down the air line, and out the tip of your airbrush.
Then contaminating your paint, and creating havoc on your work. Simply put, if your going to be doing any airbrush work. Whichever style of moisture trap you choose is totally up to you both are proficient. I personally use a perpendicular style that is mounted within the air line As seen in the right photo. However I have heard the smaller option that mounts directly to the airbrush As seen in the left photo provides somewhat of a handle, which makes holding the airbrush easier….
As the farther away from the compressor you place the trap, the more time the warm air will have to cool, and condense. Which will make the moisture trap operate better. But the closer you place it to the compressor the greater the likely hood the warm air wont have enough time to cool, and will potentially condense after the trap.
Pretty much eliminating the benefit of using a moisture trap. For these reasons a spray booth is a very useful piece of equipment if you plan to airbrush for any length of time, and well worth investing in. The model pictured above is the one I use and is widely available online. It works by drawing air through a dual-layered filter pad which collects the airborne particles of paint.
The filter pads are washable and replaceable so the booth itself will last practically forever. I tend to line the inside with paper to avoid getting paint all over the internal plastic panels. The booth also comes with a turntable which is very useful. Disposable dust masks such as you might use for DIY tasks are adequate, or you could consider something more robust such as a 3M respirator. A good solution to this is one of the widely available stands that also double as a cleaning pot.
You can safely spray any excess paint or cleaning fluid into the pot and wash it out at the end of your session. Another accessory that provides a lot of convenience is a quick-release coupling for detatching the airbrush from the air hose without the need to unscrew the connecter. The exact coupling you need will depend on your airbrush, so check with your equipment supplier to make sure you get the right one. This section is focused on the cleaning, maintenance and care of your airbrush.
You may find you have adequate tools and materials for this purpose in your household or toolbox already, but there are a couple of specialist items you may find useful and want to consider.
Most brands that offer airbrush paints also sell a corresponding cleaning fluid. Isopropyl rubbing alcohol can be used as a low cost, widely available alternative cleaning fluid for acrylic paint. You will need some cotton pads or paper towels to clean the larger parts of your airbrush, including the needle. You can moisten these with isopropyl or your chosen cleaning fluid.
Cotton swabs are very useful for cleaning the smaller parts of the airbrush and inside the paint cup. Tamiya produce scale modelling specific cotton swabs in small sizes that are much more tightly wound than the cosmetic type, and therefore particularly well suited to this job. Foam swabs are also available in various sizes. I have tried several products that claim to be designed for this purpose, but I find they often have the opposite effect and end up gumming things up.
A small bottle will last a very long time. No proprietary tools are necessary for Badger airbrushes. When it comes to the process of cleaning, the exact steps will vary depending on your make and model of airbrush. Generally speaking, you will want to flush out the paint cup with cleaning fluid between each colour change and partly disassemble the brush to clean the needle and nozzle at the end of each session. To clean out the paint cup between colour changes, empty any excess paint by inverting the airbrush and pouring back into the bottle or pot, or some other container for disposal.
Spray any remaining paint out into your cleaning pot until the airbrush sprays clean air. Now pour a little cleaning fluid into the cup, agitate with a paintbrush and invert the airbrush again to pour out. Repeat this process but this time spray the cleaning fluid through the airbrush into the cleaning pot. Repeat again until the cleaning fluid appears clear in the cup.
