2. High-efficiency Design: Customized two-stage compression screw mainframe, combined with advanced flow and constant pressure control, reduces energy consumption and ensures stable gas output.
3. Permanent Magnet Synchronous Motor: Fully enclosed, oil-cooled motor (IP65 protection) provides safe, continuous, and stable operation under high loads, boosting efficiency and durability.
4. Integrated Structure: Coaxial design of mainframe and motor eliminates traditional transmission losses, achieving 100% efficiency, lower mechanical loss, and reduced noise.
5. Intelligent Control System: Real-time monitoring and dynamic status display enable long-term, stable, unattended operation for enhanced reliability.
6. Energy Saving and High Efficiency: Compared to single-stage compression, two-stage compression increases air output by 15% and delivers up to 15% energy savings by improving volumetric and adiabatic efficiency.

Working Principle

Air first enters the initial compression chamber, where it is compressed and its temperature rises. An enhanced oil injection cooling system lowers the air temperature before it enters the second stage compression chamber, where further compression occurs under an equal pressure ratio. This process reduces power consumption and maximizes efficiency. The permanent magnet synchronous motor provides continuous power, and frequency conversion technology ensures precise adjustment of motor speed according to real-time air demand, optimizing both air output and energy use.
