Preset Fluid Control Knob

GHAD-39 Only · Rear Needle Travel Limiter

✅ GHAD-39 Only 🎛️ Paint Flow Limiter 🔧 OEM Gaahleri Part

✅ GHAD-39 (Advanced Series) only

Does not fit GHAC-98D — the Ace Series uses a different rear mechanism.

What Is This?

The rear knob on the GHAD-39 that sets a hard limit on how far back the trigger can travel — which directly caps how much paint can flow. Turn it in to restrict needle pull-back; turn it out to open up the full range.

Useful for dialling in a consistent output for repetitive tasks — base coating, priming, or any work where you want the same paint volume every stroke without actively modulating the trigger.

Practical Benefits

🎯 Hard cap on maximum output — prevents accidental over-spray on fine work

🔁 Repeatable strokes — same paint volume pass after pass without concentration

💪 Muscle memory training — set the limit while learning trigger control, remove it as skill develops

⚠️ Heads Up

GHAD-39 only. The GHAC-98D uses a different rear mechanism and is not compatible with this part.

Notes · Q & A

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.
