Unlike standard compact compressors that cut corners on the airend and motor, the ZIQI GA-AL Series integrates the same original German GHH RAND airend and WEG IE4 Super Premium motor found in our full-size industrial machines — into a plug-and-play all-in-one chassis.
Each unit combines four systems — screw compressor, air receiver tank, refrigerated dryer, and precision filters — delivering ISO 8573-1 Class 1.4.1 quality air with zero installation piping. Available in 7 models from 3.7 to 22 kW, with pressure options up to 16 bar, the GA-AL is purpose-built for fiber laser cutting, CNC machining, dental labs, food packaging, and any application demanding clean, dry compressed air in minimal floor space.

The exact same airend used in our large GAS industrial machines — not a downgraded compact version. Original German engineering delivers 15% higher free air delivery (FAD) than domestic alternatives at the same power rating.
Origin: Original German GHH RAND Engineering
Performance: 15% Higher FAD vs. domestic airends
Duty Cycle: 100% continuous operation rated
Design Life: 100,000+ hour airend life expectancy

Compact machines generate more heat per cubic meter of enclosure. The WEG IE4 motor runs cooler and wastes less energy as heat — critical for an AIO where every watt of waste heat accumulates inside the cabinet.
Efficiency: IE4 Super Premium — saves up to 15% electricity
Drive: 1:1 Direct Connection — no belt, no belt maintenance
Protection: IP55 Dust-Proof — safe in laser cutting dust
Savings: $3,000 – $8,000 in electricity over 3 years
GHH airend + WEG IE4 motor. Oil-injected rotary screw, 100% duty cycle.
ASME-certified thick-wall pressure vessel. Stabilizes pressure pulsation.
Dew point +2~10°C. Removes 95%+ moisture to protect laser lenses.
ISO 8573-1 Class 1.4.1 air quality. Oil content ≤0.01 mg/m³.
High-pressure clean air for assist gas. Protects laser optics from moisture and oil. Models up to 16 bar match most laser brands.
Stable air for tool changers, chip blowing, and pneumatic clamping. Direct-drive ensures vibration-free output next to precision machines.
62 dB(A) — quieter than a conversation. Clean filtered air for dental chairs, autoclaves, and lab instruments.
ISO-certified clean air for nitrogen generators, filling machines, and packaging lines. No oil contamination risk.

| Drive | Belt drive — replacement every 3,000–5,000 hrs | Direct drive — zero belt maintenance |
| Air Tank | Thin-wall, no certification | Thick-wall, ASME certified |
| Air Quality | Basic filter, unknown classification | ISO 8573-1 Class 1.4.1 |
| Dryer Capacity | Often undersized for rated flow | Matched to 100% of rated compressor output |
| Noise Level | 70–78 dB(A) | 62–63 dB(A) (conversation level) |
| Annual Electricity (11 kW) | ~$6,800/year (IE2 at 86% eff.) | ~$5,800/year (IE4 at 94% eff.) — save $1,000/yr |
| 3-Year Maintenance | $1,500–$2,500 (belts + filters + oil) | $600–$1,500 (filters + oil only, no belt) |
Laser cutting needs 13–16 bar + L-type (dryer). CNC/general workshop needs 7–10 bar. Food/dental needs clean air (L-type). This determines pressure and configuration.
Match your laser power to the sizing guide above, or add up total air consumption of all pneumatic tools + 20% safety margin. Choose the model that covers your peak demand.
L-type (with dryer + filters) recommended for most users — especially laser, food, dental. C-type (tank only) if you already have a separate dryer.
