Iwata is the name that comes up when an experienced painter is asked for one recommendation, and it is also the name most likely to leave a beginner confused in front of a product page. Eclipse, HP, Neo, Revolution, Custom Micron, and a string of two and three letter suffixes after each. None of it is explained on the box.
The good news is that the range makes sense once you know what the line names mean, and that the answer for most model painters is one specific brush that has been the answer for years. The rest of the catalog exists for people doing something other than what you are doing.

Quick Answer
Which Iwata airbrush should you actually buy?
- Eclipse HP-CS: the standard answer for miniatures and models. One brush, primer to detail.
- Neo CN: the entry line. A separate, cheaper product family, not a small Eclipse.
- HP series: finer tolerances and smaller nozzles, for painters who want the extra control.
- Custom Micron: exquisite and the wrong purchase for almost everyone reading this.
Bottom line: if you are here to buy one Iwata and get on with painting, it is the Eclipse HP-CS.
How the Range Is Organized
Iwata sells several distinct families rather than one ladder. Neo is the entry line. Revolution sits above it as the straightforward general purpose family. Eclipse is the workhorse tier. HP, the High Performance line, is where the tolerances tighten. Custom Micron is the top, built for the finest work anyone does with an airbrush.
Within each family the suffix tells you the configuration. C usually means gravity feed with a cup, B means a smaller gravity cup for fine work, S denotes a siphon or side feed variant depending on line, and Plus marks a revised version. Once you can read that, the catalog stops being intimidating.
Eclipse HP-CS: the Standard Answer
This is the brush that turns up in every recommendation thread, and searches for it have grown sharply. It is a gravity feed dual action with a 0.35 mm nozzle, which is the reason it works: large enough to spray primer and thicker paint without fuss, fine enough for the detail most model painters actually do.
The practical appeal is that you do not swap anything. One brush, one nozzle, from priming a chassis to picking out a face. It is also robustly built and easy to strip, which matters more over a decade than any single specification. Our full Eclipse HP-CS guide covers it in detail.
Neo Is a Separate Line, Not a Small Eclipse
This is the single most useful thing to know about the Iwata range. The Neo carries the Iwata name and is designed by Iwata, and it is a different product family built to a lower price in a different factory. It is not a scaled down Eclipse and its parts do not interchange with one.
That does not make it a bad brush. As an entry point it is decent, and the Neo CN is a capable gravity feed dual action for someone stepping up from a bundled kit brush. Just buy it knowing what it is, rather than believing you are getting Eclipse engineering for less. Our Neo CN guide is the honest version.
The Lines at a Glance
The table sets the families out by what they are for. Nozzle sizes vary by model within a line, so treat these as the typical case rather than a full specification.
| Line | Typical nozzle | Built for | Worth knowing |
|---|---|---|---|
| Neo | 0.35 mm on the CN | Entry level, first real brush | Separate family, parts do not cross to Eclipse |
| Revolution | Around 0.5 mm on the CR | General purpose, larger coverage | Handles thicker paint easily |
| Eclipse | 0.35 mm on the HP-CS | Models and miniatures, all round | The default recommendation |
| HP series | Finer, varies by model | Control at the fine end | Tighter tolerances, less forgiving of thick paint |
| Custom Micron | Very fine, down to 0.23 mm | The finest freehand work | Wrong purchase for most model painters |
The HP Series and Where It Helps
HP stands for High Performance, and the line is built to closer tolerances with generally finer nozzles than the Eclipse. In use that means better atomization at low pressure and more control at the very fine end, which a painter doing freehand detail and smooth blends will feel.
It also means less tolerance for thick paint and a slightly more demanding cleaning routine. If your painting is mostly basecoats and primer with occasional detail, the Eclipse is the better tool. If you are chasing fine control and are already thinning carefully, the HP line is where that effort starts paying off.
Why the Custom Micron Is the Wrong Answer
Because it is a specialist instrument whose advantages appear only once everything else is perfect. A very fine nozzle demands very consistent thinning, very clean paint and very steady pressure, and it punishes anything less with clogs and tip dry. A painter still learning those things will have a worse time, not a better one.
It is also the most expensive way to discover that your bottleneck was the thinning. Get consistent results with an Eclipse first, and if you then find the brush is the thing holding you back, the Micron will still be there. Our guides to thinning acrylic paint and nozzle size explain why.
Where to Buy and What About Parts
Iwata sells through both Amazon and the hobby dealer network, and the split matters. The mainstream models are easy to find from major sellers, while some specific configurations move mostly through specialist dealers who also stock the needles, nozzles and seals.
That parts availability is a real part of what you are buying. Needles bend, nozzles crack, and an airbrush you can rebuild is one you keep. Our guide to airbrush replacement parts covers what is worth replacing, and what to do with a bent needle covers the most common casualty.
Frequently Asked Questions
Is the Iwata Neo a real Iwata? It carries the name and the design input, and it is a separate entry level family made to a lower price, not a smaller Eclipse. Judge it as a good starter brush rather than as a discounted premium one, and do not expect Eclipse parts to fit.
Which Iwata nozzle size for miniatures? The 0.35 mm on the Eclipse HP-CS covers the whole job for most painters, from primer to detail. Going finer only pays off once your thinning and pressure are consistent. Our guide to airbrush nozzle size sets out what each size suits.
Do I need an Iwata compressor with an Iwata airbrush? No. Any compressor with a regulator and a moisture trap will run one, and the fitting is the standard 1/8 inch BSP. Our guide to the Iwata airbrush compressor covers what the branded units add, which is quiet and build rather than spray quality.
Eclipse or Harder and Steenbeck Evolution? They sit at the same tier and painters are genuinely split. The Eclipse is more forgiving of thicker paint; the Evolution has a different trigger feel and a quick change needle system. Our head to head works through it.
Can I convert an Eclipse to a different nozzle size? Yes, conversion parts exist for the Eclipse family, and a larger nozzle set is a common change for painters who prime a lot. It is a parts purchase rather than a new brush, which is one of the reasons the line has stayed popular.
The Bottom Line
If you want one Iwata and no further research, buy the Eclipse HP-CS and spend the saved effort on thinning practice. The Neo is a separate entry family rather than a cheap Eclipse, the HP line rewards painters who are already consistent, and the Custom Micron is the wrong first, second or third airbrush for almost everyone.
