Does an Airbrush Kit Include Everything You Need? A Starter Checklist
The Honest Answer: It Depends on the Kit
Some bundles include all five components and are genuinely ready-to-spray on day one. Others include a capable airbrush but pair it with a compressor that cannot sustain the air pressure a beginner needs, or they skip the cleaning supplies entirely.
Before you buy, run through the checklist below — it takes two minutes and will tell you exactly what a particular kit covers and what it doesn't.
Airbrush
Precision Modeling Essential
Often included: A dual-action gravity-feed brush with a 0.3–0.35 mm nozzle, a common starting point for models and miniatures. This is an example, not a requirement.
If it differs: Single-action and siphon-feed brushes can still produce good work; check that the brush suits the subjects and detail you plan to paint.
Compressor
The Heart of Your Setup
Often included: An oil-free piston compressor, sometimes around 1/8 hp with a 1–2 litre tank. Treat those figures as context, not kit minimums: airflow and the pressure you need depend on the airbrush, paint and subject.
If it differs: Check the compressor's stated working range against the pressure your airbrush and paint need. Propellant cans suit short jobs but drop pressure as they chill.
Air Hose
The Vital Connection
Check: That the hose and fittings actually match your airbrush and compressor. 1/8 BSP is common, but it is not universal, and a bundle does not guarantee a match.
If it doesn't fit: You will need an adapter or a different hose before the airbrush can connect.
Cleaning Supplies
Long-Term Maintenance
Check: That the kit includes cleaning brushes and a pot or jar, or that you have them already.
If it doesn't: Cleaning takes longer and dried paint is more likely to clog the brush, especially with acrylics.
Practice Medium
Testing & Calibration
Check: For a test paint or a surface you can spray, plus water or the cleaner the airbrush maker recommends.
If it doesn't: You can still test with water or a spare surface, then calibrate pressure once you load paint.
What the Airbrush in the Kit Tells You About Your Next Year
Feed system — gravity or siphon?
A gravity-feed airbrush can often work at lower pressure and is usually easier to clean. Many starter kits for modellers use gravity-feed, but siphon-feed brushes remain common too.
Action type — single or dual?
A dual-action brush lets you control air and paint independently. Single-action brushes are cheaper and can still do useful work; they are not automatically outgrown.
Nozzle size — what fits your subject?
A 0.3–0.35 mm nozzle is a common choice for scale models and miniatures. Check the nozzle size against your intended use before assuming the kit fits your subject.
Buy a starter kit
A bundle can save you the matching problem, and it is a lower-risk entry point if the parts are compatible. Check the fittings and compressor specs rather than assuming they match, and expect to replace individual pieces later as you specialise.
Buy separately
If you already know you want a specific high-end airbrush, you get more capability per dollar by choosing the compressor independently. The downside is the matching work: hose fittings, PSI range, and tank size all need to be verified before you buy.
Airbrush Compressor Size Calculator →What Most Airbrush Kits Don't Include
Thinning Medium
Most hobby paints need to be thinned to atomize correctly. Kits almost never include thinner.
Water Trap
Prevents moisture in the line from causing paint to spit. Most budget kits skip this essential filter.
Spray Booth
Ventilation is a safety requirement, not an option. These are rarely included in standard kits.
Needle Lubricant
Keeps the needle sliding smoothly and extends seal life. Not included in most kits.
Practice Substrate
You need test cards or old sprue pieces to calibrate pressure before spraying your actual model.
Before You Buy Any Airbrush Kit, Do This First
Check the compressor's stated working pressure and airflow against the airbrush and paint you plan to use, confirm the hose fittings match, and make sure cleaning tools are included or already on your bench. Avoid the frustration of a kit that doesn't fit your needs.

Frequently Asked Questions
Is an airbrush kit with compressor worth buying?
For many beginners, a kit can be a reasonable start because it reduces the matching work. Verify the compressor's stated output and tank size for the sessions you plan, rather than assuming the bundle is sized for them.
Can I use an airbrush kit for scale models?
It can work for scale models if the brush and compressor suit the job. A dual-action gravity-feed brush with a 0.3–0.35 mm nozzle is a common choice, but 15–25 PSI is a starting range, not a universal requirement. Check the compressor's stated working range and whether it holds pressure through the sessions you plan.
What's missing from most cheap airbrush kits?
Thinning medium, a moisture filter/water trap, and adequate ventilation are the most common omissions.
Do I need a compressor, or can I use an aerosol propellant can?
Aerosol cans drop pressure as they empty and run cold. For regular use, many painters prefer a piston compressor.
