Single-phase power supply (220V) : Suitable for households, small workshops or places with limited power infrastructure. It can operate without three-phase electricity, lowering the installation threshold.

Flexible deployment: Especially suitable for remote areas or temporary operation scenarios without three-phase power.

2. High efficiency and energy saving

Advantages of screw technology: Stable continuous gas supply, energy saving about 15%-30% compared with piston machines. For some models, variable frequency control can further reduce no-load energy consumption.

Low-maintenance design: Reduces frictional losses (such as without piston rings), and slows down energy efficiency decline over long-term use.

3. Low noise and vibration

Silent operation: Screw structure + noise reduction design, the noise is usually controlled at 60-70 decibels (it can be even lower if a sound insulation cover is used), suitable for noise-sensitive environments (such as residential areas and laboratories).

4. Compact structure and lightweight

Compact size: Compared with piston machines of the same power, it saves 30% to 50% of space, is easy to move, and is suitable for space-limited situations (such as vehicle repair shops).

5. Stable and reliable

Continuous working capacity: Good heat dissipation, supporting 24-hour operation (such as medical gas supply, small production lines), with a lower failure rate than piston machines.

6. Easy to maintain

Few components: There is no need to frequently replace piston rings, valves and other parts. Only the oil level and filter element need to be checked daily, reducing maintenance costs by more than 50%.

7. Wide range of application scenarios

Small-scale demands: such as woodworking tools (spray guns, nail guns), small-scale sandblasting, pneumatic packaging equipment, etc. The flow rate usually covers 0.5-3m³/min, and the pressure is 8-13bar.

Notes:

Power limit: The power of single-phase models is generally ≤7.5kW, suitable for medium and small gas volume demands (three-phase models are required for large flow rates).

Cost trade-off: The initial investment is higher than that of piston machines, but the long-term usage cost is lower.

Typical application scenarios: home DIY, dental clinics, small auto repair shops, food processing (such as packaging inflation), and other occasions that require a stable and low-noise air source
