- What it is: a TC-320 1/5 hp dual-fan compressor plus three airbrushes, six acrylic colors and a quick start guide.
- Airbrush range: 0.2 mm (G25), 0.3 mm (G22) and 0.8 mm (E91), so fine lines to broad coverage.
- Compressor: 25 L/min and 0.8 cfm with a 0 to 57 psi regulator, per the standalone TC-320 listing.
- Main trade-off: no air tank, so pick the TC-326T or TC-426 kits if pulse-free air matters.
This Master Airbrush Cool Runner II review looks at the kit most people picture when they think of a starter airbrush system. It bundles the TC-320 Cool Runner II compressor with three airbrushes and a starter set of acrylic paint.
Everything below comes from the maker's listings for the kit and for the TC-320 sold on its own. Treat it as a careful on-paper read before you check price. For the wider field, see all airbrush kits.
Master Airbrush Cool Runner II Air Brush Kit with Air Compressor Dual Fan
On paper, the Cool Runner II kit is one of the most complete ways to start airbrushing. Three airbrush styles cover detail, general and broad spraying, and the dual-fan TC-320 is built for longer sessions. The lack of an air tank is the one clear compromise.
- Beginners who want to try gravity and siphon feed
- Hobbies, crafts, models and auto graphics
- Anyone who wants paint and cleaning gear in the box
- Painters who need pulse-free air at very low pressure
- Studios running two airbrushes at once
- Cake decorators, who need food-only airbrushes
What comes in the Cool Runner II kit?
The listing names each part, so the box is easy to map:
| Part | Key specs from the listing |
|---|---|
| TC-320 Cool Runner II compressor | 1/5 hp single piston, two cooling fans |
| G22 airbrush | Dual-action gravity feed, 0.3 mm tip, 1/3 oz cup |
| G25 airbrush | Dual-action gravity feed, 0.2 mm tip, 1/16 oz cup |
| E91 airbrush | Single-action siphon feed, 0.8 mm tip, two 3/4 oz bottles |
| Paint | 6 opaque acrylic colors in 1 oz bottles, plus reducer and cleaner |
| Extras | Holder for 2 airbrushes, hose, mixing wheel, cleaning brush set, quick start guide |
The six colors are bright sapphire blue, grass green, bright yellow, bright red, deep black and white. With the double-sided mixing wheel, that is enough to mix most hues while you learn.
How the three airbrushes compare
Each airbrush covers a different job, which is the main reason to pick this kit over a single-airbrush set.
G22: the everyday workhorse
The 0.3 mm tip and 1/3 oz gravity cup suit general coverage with decent detail. Master Airbrush calls it its top-selling gravity airbrush, rated for up to 1-1/2 inch wide background spray.
G25: fine detail
A 0.2 mm tip and a tiny 1/16 oz cup make it the choice for thin lines and quick color changes with small amounts of paint.
E91: broad and simple
Single-action and external mix, the E91 only controls air from the trigger. Its 0.8 mm tip and 3/4 oz bottles handle thicker paint and backgrounds. Our gravity feed vs siphon feed airbrush guide explains when each feed style helps.

TC-320 compressor: what the specs say
The kit listing describes a 1/5 hp single-piston compressor with two cooling fans that let it run cooler for longer without overheating. The standalone TC-320 listing adds the numbers:
- Airflow of 25 liters per minute, or 0.8 cfm
- Air pressure range of 0 to 57 psi
- True diaphragm regulator with gauge and a water trap filter
- Oil-less, maintenance free, 47 dB
- Air-on-demand automatic shut-off and a carrying handle
There is no air storage tank. The TC-326T adds a 3 liter tank with the same 25 L/min motor; the TC-320 vs TC-326T comparison covers the difference. All models sit on the air compressors page.
Master Airbrush Cool Runner II review: pros and cons
| Strengths | Trade-offs |
|---|---|
| ✓ Three airbrushes from 0.2 to 0.8 mm | ✗ No air tank |
| ✓ Dual cooling fans for longer runs | ✗ Holder fits 2 of the 3 airbrushes |
| ✓ Paint, reducer and cleaner included | ~ Hose length not stated in the kit listing |
| ✓ Mixing wheel and cleaning brushes | ~ Single-piston airflow suits one airbrush at a time |
If those trade-offs matter, these bundles solve them: a tank version with a 10 foot hose, a deluxe kit with a 3 liter tank and 24 colors, and a twin-piston kit.

Setup is short once you know the order. A simple sequence to follow:
- Place the compressor on a flat, stable surface with space around the fans for airflow.
- Connect the hose to the compressor outlet, then to the G22 for your first session.
- Set a moderate pressure on the regulator gauge before you add paint.
- Spray cleaner through the airbrush to check for leaks and a steady pattern.
- Thin the acrylics with the included reducer and practice on paper.
- Flush with cleaner after each color, then park the airbrush in the holder.
Start with the G22, since its 0.3 mm tip forgives small mistakes in paint thinning. Move to the G25 once fine lines feel natural, and save the E91 for backgrounds and larger pieces where speed matters more than precision.
Who should buy it, and what to add
Buy it if you are new to airbrushing and do not yet know whether you prefer detail or coverage work. Skip it if you already own an airbrush and only need air; the standalone TC-320 fits that better.
Useful first add-ons are a cleaning kit and spare parts. The Master Airbrush repair kits list the G22 and G25 among the fitted models.

Our verdict comes down to range. Three airbrushes, a dual-fan 1/5 hp compressor and six colors make it a complete first system for hobbies, crafts and models, according to the maker.
If you want pulse-free air, step up to a tank kit such as the TC-426 system. If you only need one fine airbrush, the best gravity feed airbrush list is a better start.
