Product Description
The CMGSP1 is a revolutionary pneumatic (air‑powered) espresso machine that requires no electricity and no preheating. Designed for coffee lovers who want professional‑grade espresso anywhere – at home, in the office, or outdoors – it uses a 58mm commercial bottomless portafilter and achieves 1‑16 bar extraction pressure (9 bar gold pressure recommended). The custom PC chamber provides excellent heat retention without preheating, outperforming traditional stainless steel. The kit includes all essential accessories: a 58mm tamper, dosing ring, distribution tool, secondary water diffusion screen, and espresso cups. Whether you pair it with CO₂ cartridges, an electric air pump, or a manual pump (not included), you get consistent, rich crema in seconds.
Key Advantages
✅️ No Electricity, No Preheating
Runs entirely on compressed air (external pump/cartridge not included). The PC chamber starts at room temperature and retains heat efficiently – ready to brew instantly.
✅️ Superior Heat Retention with PC Material
Polycarbonate has a thermal conductivity of only 0.2 W/m·K (vs. 16‑17 for stainless steel). One‑minute temperature loss is only 3‑10°C, compared to ~20°C for steel. Your espresso stays hot.
✅️ 58mm Commercial‑Grade Extraction
Includes a professional 58mm bottomless portafilter (precision laser‑cut holes) and a 58mm tamper. Extracts evenly without channeling or splashing, producing rich crema.
✅️ Visible Pressure Gauge (1‑16 bar)
Real‑time pressure monitoring helps you dial in the perfect shot. Adjust air input to achieve the recommended 9 bar for optimal flavor.
✅️ Complete All‑in‑One Kit
Comes with: 58mm bottomless portafilter, 58mm tamper, dosing ring, distribution tool, secondary water diffusion screen, and two espresso cups. Start brewing right away.
✅️ Multiple Air Source Options
Compatible with stainless steel CO₂ cartridges, electric air pumps, or high‑pressure hand pumps (not included). Choose what works best for you – at home or on the trail.
✅️ Compact, Portable & Easy to Maintain
Dimensions 27×12×17cm, weight only 2.7kg. The minimalist design is easy to disassemble and clean. Comes with a 304 stainless steel drip tray (grid design) for quick drainage.
✅️ Safety Pressure Relief Valve
Quickly releases residual air after extraction. Always depressurize before disassembling the chamber.
