🎯 Gaahleri GHPM‑Mobius SP · 0.3 & 0.5 mm
Siphon‑Feed Dual‑Action · Dual Nozzles · Glass Bottle · Works from 15 PSI
🔍 What Is This?
The siphon‑feed Mobius. Same dual‑action precision as the gravity‑fed Mobius lineup, but with a glass bottle siphon system for higher paint capacity and quick colour swaps. Ships with two nozzle/needle sets (0.3 mm + 0.5 mm) and works from as low as 15 PSI — unusually low for a siphon airbrush. Built for users who want gravity‑level atomisation with siphon‑feed convenience.
🍶 Why Siphon? What's Different from Gravity?
More paint, fewer refills
A siphon bottle holds significantly more paint than a gravity cup. Means less stopping to reload when basecoating large models, terrain, or doing extended coverage work.
Instant colour changes
Pre‑mix multiple bottles — swap them out instead of flushing the cup. If you work with 5–10 colours per session, this saves real time.
Works from 15 PSI
Most siphon airbrushes need 20+ PSI to draw paint reliably. The Mobius SP works from 15 PSI — less overspray, better control on detail work, and compatible with smaller compressors.
👤 Who Is It For?
✅ Great fit
Painters who work on large surfaces and need high paint capacity — terrain, dioramas, vehicle bodies, canvases, backgrounds — but also want to switch to detail mode (0.3 mm) without changing airbrush. Also ideal if you frequently swap between many pre‑mixed colours and want fast bottle changes over cup flushing.
⚠️ Less ideal
If you primarily paint small miniatures and rarely need more than 10 ml of a single colour, a standard gravity cup is simpler and lighter. If you need extreme 0.2 mm micro‑detail, a dedicated gravity fine‑line airbrush is still the better tool for that specific job.
⚖️ Two Nozzles, Two Modes
| 🔬 0.3 mm | 🎯 0.5 mm (Spiral MAC) | |
| Fine lines | ✅ Good (gravity‑like) | Limited |
| Blending | ✅ Smooth, controlled | Good, broad |
| Coverage speed | Moderate | ✅ Very fast |
| Primers / varnish | Possible (thin well) | ✅ Built for it |
| Min. PSI | ✅ From 15 PSI | ~20 PSI recommended |
| Best for | Detail, preshading, minis, line work | Large surfaces, primers, backgrounds, terrain |
💡 The 0.5 mm set uses the Spiral MAC nozzle and is fully cross‑compatible with other Mobius airbrushes — one spare fits across your Mobius collection.
🛠️ What Makes It Different
| 🍶 Glass Siphon Bottle | Metal‑capped glass bottle — easy to clean, won't degrade from solvents like plastic, and seals properly every time. Buy extra bottles to pre‑mix colours and swap them in seconds. |
| 💨 15 PSI Minimum | Most siphons struggle below 20 PSI. The Mobius SP's air channel design lets it draw paint reliably from 15 PSI — less overspray, better fine control, and works with smaller/quieter compressors. |
| 🌀 Spiral MAC Nozzle (0.5) | Spiral micro air channel on the 0.5 mm nozzle — optimised for high‑volume, high‑efficiency coverage. Fast, even coating with stable atomisation across the full pattern. |
| ◼️ Redesigned Lever | Larger finger contact surface with refined angles — smoother action and less fatigue than standard levers, especially during long coverage runs. |
| 📐 Angled Air Valve | Air valve positioned at an angle so your hand doesn't clash with the siphon bottle below. Small design detail that makes a real difference in grip comfort. |
| ⚖️ Aluminium Tail Grip | Anodised aluminium rear grip (purple‑blue Gaahleri finish) — lightweight, shifts balance slightly forward to compensate for the siphon bottle weight below. More comfortable than tail‑heavy designs. |
📋 Technical Specifications
| Type | Dual‑Action, Internal Mix, Siphon‑Feed |
| Nozzles Included | 0.3 mm + 0.5 mm (Spiral MAC) |
| Working Pressure | 15–40 PSI (1–2.7 bar) · stable from 15 PSI |
| Feed System | Glass siphon bottle, metal cap + metal fittings |
| Trigger | Redesigned top‑lever with wider contact surface |
| Air Valve | Angled — clears siphon bottle for natural grip |
| Rear Grip | Anodised aluminium (purple‑blue), forward‑biased balance |
| 0.5 mm Compatibility | Cross‑compatible with other Mobius airbrushes |
| Best For | Large surfaces + detail · high‑capacity siphon work · multi‑colour sessions |
⚠️ Honest Heads‑Up
More Parts to Clean
Siphon bottle + metal cap + metal fittings + dip tube = more components to flush and maintain than a simple gravity cup. The glass cleans easily, but the routine is longer. If you value absolute simplicity, a gravity‑feed Mobius is less hassle.
Siphon Adds Weight Below
A full bottle hangs below the airbrush — changes the balance and feel compared to a gravity‑feed. The angled valve and forward‑weighted aluminium tail help, but it's different. If you've never used a siphon, try holding your airbrush with a small weight underneath to see if the feel suits you.
0.3 mm Siphon ≠ 0.2 mm Gravity
The 0.3 mm gives you gravity‑like precision in a siphon body — impressive for the format. But for extreme micro‑detail (sub‑0.2 mm freehand), a dedicated gravity fine‑line airbrush still has the edge.
