China Two-Stage Screw Air Compressor Factory - Energy Efficient Solutions from Top Suppliers
Air-end
🏆 Level 1 Energy Efficiency Certified
Two-stage compression compared to single-stage compression tends toward the most energy-efficient isothermal compression. From the principle, two-stage compression saves 5–8% energy over single-stage compression.
⚡ Saves 10%–15% energy vs. Level 2 Energy Efficiency Grade | Saves 20%–30% energy vs. Level 3 Energy Efficiency Grade
- Adopts two-stage independent compression
- Equal pressure ratio over both stages with lower compression speed, improving volumetric efficiency
- Oil mist spray cooling between stages makes the entire compression process close to isothermal compression, improving compression insulation efficiency
- Two-stage rotors directly driven by bevel gear respectively, ensuring high compression transmission efficiency
- Large diameter and low-speed rotors reduce bearing stress, lengthening lifespan of bearings and other components
Controller
- LCD HD touch monitor with PLC control and human-friendly menu interface design
- Displays multi-line operation parameters and historical records at a glance

Frequently Asked Questions
QWhat is the advantage of two-stage compression over single-stage compression?
Two-stage compression is closer to isothermal compression, which is the most energy-efficient compression method. Compared to single-stage compression, two-stage compression saves approximately 5–8% energy. Additionally, it achieves Level 1 Energy Efficiency Certification, saving 20–30% more energy than Level 3 grade compressors.
QWhat type of controller does the air compressor use?
The air compressor features an LCD HD touch monitor with PLC control and a human-friendly menu interface. It can display multiple lines of operation parameters and historical records, making daily operation, inquiry, and maintenance simple and convenient.
QWhich inverter brands are used in the air compressor?
We use inverters from internationally recognized brands including Megmeet, Inovance, and Zoncn. These brands are known for their stable, reliable quality and excellent after-sales service, ensuring the safest and most efficient operation of the air compressor system.
QWhat are the key features of the motor used in this air compressor?
The main motor is an IP55 high-efficiency permanent magnet motor that meets national energy efficiency standards. It features F-class insulation, B-class temperature rise, effective dust prevention, and SKF heavy-duty bearings for long-term continuous trouble-free operation. Other IP protection levels are also available upon request.
QHow does oil mist spray cooling benefit the compression process?
Oil mist spray cooling is applied between the two compression stages to significantly reduce the temperature of the compressed air. This makes the entire compression process approach isothermal compression, improving compression insulation efficiency and overall energy savings.
QHow does the two-stage rotor design extend component lifespan?
The two-stage rotors feature large diameters and operate at low speeds, which significantly reduces the mechanical stress placed on bearings and other internal components. This design not only extends the lifespan of the bearings but also reduces wear on all related parts, resulting in lower maintenance costs and longer service life.
