China Two-Stage Screw Air Compressor - Efficient Energy Solutions from Leading Suppliers and Factory
Air-end
⭐ Level 1 Energy Efficiency Grade Certified
Two-stage compression compared to single-stage compression, the two compression tends to the most provincial power of the isothermal compression. From the principle, the single-stage compression of the two compression energy saving 5~8%.
Won the award of Level 1 Energy Efficiency Grade Certification.
· Compared with Level 2 Energy Efficiency Grade — Save 10%–15% energy.
· Compared with Level 3 Energy Efficiency Grade — Save 20%–30% energy.
· Compared with Level 2 Energy Efficiency Grade — Save 10%–15% energy.
· Compared with Level 3 Energy Efficiency Grade — Save 20%–30% energy.
- Adopt two-stage independent compression.
- The pressure ratio is equal over both stages as well as having a lower compression speed, which helps improve volumetric efficiency.
- Oil mist spray cooling is used between the stages to make the entire compression process close to isothermal compression and improve the compression insulation efficiency.
- The two-stage rotors are directly driven by the bevel gear respectively, and the compression transmission efficiency is high.
- The large diameter and low speed of the rotors reduce stress on the bearings, thus lengthening their life span as well as any other components.
Controller
- LCD HD touch monitor, PLC control, Human menu interface design.
- Can display multi-line operation parameters and historical records.
- Simple operation, easy inquiry, and convenient maintenance.
Inverter
The inverter is the brain of the air compressor, and all operations of the air compressor are processed and regulated through the inverter, ensuring the safe and reliable operation of the air compressor system in all aspects.
We typically use inverters from internationally renowned brands with stable and reliable quality and guaranteed after-sales service, providing customers with the best possible air compressor user experience.

Frequently Asked Questions
QWhat is the main 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 can save 5–8% energy from a principle standpoint, and with Level 1 Energy Efficiency Grade certification, it can save up to 20–30% compared to Level 3 units.
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 operation, inquiry, and maintenance simple and convenient.
QWhich inverter brands are used in the air compressor?
We use inverters from internationally renowned brands including Megmeet, Inovance, and Zoncn. These brands are known for their stable and reliable quality and excellent after-sales service, ensuring safe and reliable operation of the air compressor system.
QWhat motor protection rating does the air compressor use, and can it be customized?
The standard motor uses an IP55 protection rating, which effectively prevents dust ingress. Other IP protection levels are also available upon request to meet different application environments and customer requirements.
QWhat insulation class does the motor use and how does it benefit operation?
The motor uses F-class insulation with B-class temperature rise. This combination provides a higher safety margin, reduces heat-related wear, and contributes to the long-term, trouble-free operation of the compressor along with SKF heavy-duty bearings.
QHow does oil mist spray cooling between compression stages improve efficiency?
Oil mist spray cooling is applied between the two compression stages to reduce the temperature of the compressed air before it enters the second stage. This makes the overall compression process approach isothermal compression, significantly improving compression efficiency and reducing energy consumption.
