China Suppliers Two-Stage Screw Air Compressor Factory - Energy Efficient, Durable, and High-Performance Solutions
Air-end
🏆 Level 1 Energy Efficiency Certified
Two-stage compression tends toward isothermal compression — the most energy-efficient approach. Compared to single-stage compression, two-stage compression saves 5–8% energy. Compared to Level 2 Energy Efficiency Grade: saves 10%–15%. Compared to Level 3: saves 20%–30%.
- ▶ Adopts two-stage independent compression.
- ▶ Equal pressure ratio over both stages with lower compression speed, improving volumetric efficiency.
- ▶ Oil mist spray cooling between stages keeps the compression process close to isothermal, improving insulation efficiency.
- ▶ Two-stage rotors are directly driven by bevel gears, ensuring high transmission efficiency.
- ▶ Large diameter, low-speed rotors reduce bearing stress, extending the lifespan of bearings and other components.
Controller
- ▶ LCD HD touch monitor with PLC control and human-friendly menu interface design.
- ▶ Displays multiple lines of operational parameters and historical records simultaneously.
- ▶ Simple operation and inquiry interface for convenient maintenance.
Inverter
The inverter is the brain of the air compressor. All operations are processed and regulated through it, ensuring safe and reliable system performance across all aspects.
We use inverters from internationally renowned brands with stable, reliable quality and guaranteed after-sales service — delivering the best user experience.

Motor
- ▶ IP55 high-efficiency energy-saving permanent magnet motor, carefully selected for air compressor applications. (Other IP levels available.)
- ▶ Meets national energy efficiency standards with F-class insulation and B-class temperature rise.
- ▶ Effectively prevents dust ingress.
- ▶ SKF heavy-duty bearings ensure continuous, trouble-free long-term operation.
Frequently Asked Questions
Q What is the advantage of two-stage compression over single-stage compression?
Two-stage compression approaches isothermal compression, which is the most energy-efficient method. It saves 5–8% energy compared to single-stage compression, and depending on the energy efficiency grade comparison, can save up to 20–30% energy.
Q What energy efficiency certification does the air-end hold?
The air-end has won the Level 1 Energy Efficiency Grade Certification — the highest level — saving 10–15% energy over Level 2 and 20–30% over Level 3 efficiency grades.
Q What type of controller is used in the air compressor?
The air compressor uses an LCD HD touch monitor with PLC control and a human-friendly menu interface. It can display multiple operational parameters simultaneously and provides easy access to historical records for convenient maintenance.
Q Which inverter brands are used, and why?
We use inverters from Megmeet, Inovance, and Zoncn — all internationally recognized brands known for stable, reliable quality and strong after-sales service, ensuring the best possible user experience for air compressor operation.
Q What are the key features of the motor used in the air compressor?
The motor is an IP55 high-efficiency permanent magnet motor meeting national energy efficiency standards. It features F-class insulation, B-class temperature rise, effective dust protection, and SKF heavy-duty bearings for long-term trouble-free operation. Other IP levels are also available upon request.
Q How does the two-stage rotor design benefit the air compressor's longevity?
The large-diameter, low-speed rotors in the two-stage design significantly reduce stress on bearings and other mechanical components. This leads to a longer lifespan for bearings and related parts, reducing maintenance frequency and overall operating costs.
