View · Overview

Product overview

The GP-850 is a spray gun rather than a detail airbrush — Sparmax's own box names it that way. A 125 ml cup, a pistol trigger and interchangeable spray caps put it at the far end of the bench from a 7 ml detail tool. It's what you pick up for a large surface: an RC body shell, a big-scale model, or a wall, where the fan pattern earns its place by laying an oval rather than a circle.

  • Round cap sprays a 3–50 mm circle; the fan cap lays down a 25–63 mm oval with little overspray.
  • The fan cap needs a compressor that can supply at least 1.2 cfm — check yours before relying on it.
  • Uses replaceable PTFE needle packing, and carries Sparmax's five-year warranty (wear parts excluded).

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.
