Product features
1. High Efficiency and Energy Saving
Two-stage compression reduces energy consumption, saving 10%-15% compared to single-stage.
2. Stable High Pressure
Staged compression achieves higher exhaust pressure (up to 1.3 MPa and above) with minimal fluctuation.
3. Long Life
Balanced load distribution reduces wear on individual stages and extends the life of core components.
4. Intelligent Variable Frequency
Permanent magnet motor + variable frequency regulation adapts to varying load demands and avoids frequent starts and stops.
Application Industries
High-pressure requirements
Industrial equipment such as laser cutting, CNC machine tools, and injection molding machines.
Continuous high loads
24/7 manufacturing, chemical, and metallurgical industries.
Energy-saving retrofits
Replacing traditional single-stage air compressors in energy-intensive enterprises.
FAQ
1. What are the advantages over a single-stage unit?
Lower energy consumption, more stable exhaust, and suitable for high-pressure and continuous operation scenarios.
2. Is maintenance more complex?
The two-stage structure is slightly more complex, but the maintenance cycle is similar to that of a single-stage unit, requiring regular inspection of bearings and gears.
3. Is it suitable for low-pressure needs?
The cost-effectiveness for low-pressure scenarios is not high, and a single-stage unit is more economical.
4. Are the energy-saving figures realistic?
Measured energy savings are over 10% (especially at load rates >70%).
5. Disadvantages?
High initial cost and large size require careful installation space planning.
