Product Information
š¶ GHPMāMobius SP 0.3 & 0.5 mm
Premium Series Ā· SiphonāFeed Ā· Dual Nozzles Ā· Works from 15 PSI
š What Is This?
The siphonāfeed Mobius. Same dualāaction precision as the gravityāfed Mobius lineup, but with a glass bottle siphon system for higher paint capacity and quick colour swaps. Two nozzle/needle sets (0.3 mm + 0.5 mm Spiral MAC). Works from as low as 15 PSI ā unusually low for a siphon airbrush.
š¤ Who Is It For?
ā Great fit
Painters working on large surfaces needing high paint capacity ā terrain, dioramas, vehicles, canvases ā who also want detail mode (0.3 mm) without changing airbrush. Also ideal for multiācolour sessions with fast bottle swaps.
ā ļø Less ideal
If you mainly paint small miniatures and rarely need more than 10 ml, a standard gravity cup is simpler and lighter. For extreme 0.2 mm microādetail, a dedicated gravity fineāline airbrush is still better.
š¶ Why Siphon?
More paint, fewer refills
Bottle holds significantly more than a gravity cup. Less stopping when basecoating large models or terrain.
Instant colour changes
Preāmix multiple bottles, swap them in seconds instead of flushing. Huge time saver for multiācolour work.
15 PSI minimum
Most siphons need 20+. Less overspray, better fine control, compatible with smaller/quieter compressors.

š ļø Key Features
| š¶ Glass Bottle | Metalācapped glass ā easy to clean, won't degrade from solvents. Buy extras to preāmix colours and swap in seconds. |
| š Spiral MAC (0.5) | Spiral micro air channel optimised for highāvolume coverage. Fast, even coating with stable atomisation. |
| ā¼ļø Redesigned Lever | Larger contact surface, refined angles ā smoother action, less fatigue during long coverage runs. |
| š Angled Air Valve | Positioned so your hand doesn't clash with the siphon bottle. More natural grip. |
| āļø Aluminium Tail | Anodised aluminium rear grip (purpleāblue) ā lightweight, shifts balance forward to compensate for bottle weight below. |

ā ļø Honest HeadsāUp
ā¢ More parts to clean ā bottle + cap + fittings + dip tube. Glass cleans easily but the routine is longer than a gravity cup.
ā¢ Bottle weight below changes balance vs gravityāfeed. Angled valve and aluminium tail help compensate.
ā¢ 0.3 mm siphon ā 0.2 mm gravity for extreme microādetail.

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 ā 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.
