✅ GHAD-39 (Advanced Series) only — does not fit GHAC-98D or other models
What Is This?
Opens and closes airflow when you press the trigger down. A faulty valve bleeds air when the trigger is at rest, or fails to open fully when pressed — making controlled atomisation impossible.
When You Need This Part
⚠️ Air leaks at rest — audible hiss when trigger is not pressed
⚠️ No airflow control — trigger doesn't open or close air correctly
⚠️ Pulsing or unstable spray — pressure fluctuations mid-stroke
⚠️ Valve sticks or grinds — uneven resistance on trigger press
⚠️ Heads Up
GHAD-39 only. Not compatible with GHAC-98D. If unsure, message us with your model number before ordering.

What nozzle size do I need for miniatures?
0.3mm is the versatile all-rounder for base coats and priming; 0.2mm suits fine detail work. Larger nozzles (0.5mm) are for terrain and big surfaces.
Do I need a compressor with a tank?
A tank smooths the airflow and reduces pulsing, giving more consistent results — worth it if you spray regularly, but tankless compressors work fine for occasional use.
How do I keep an airbrush working well?
Flush with airbrush cleaner between colours and strip-clean after each session. Most spraying problems are cleaning problems.
