Working Principle & Structure
High-Speed Compression
Opposite rotor rotation creates negative pressure to draw in external air.
Oil-Free Compression
Zero-contact internal design ensures 100% oil-free and pure air delivery.
Conveying Stage
Rotors seal and transport air through the precision chamber toward the discharge.
Discharge Stage
Decreasing chamber volume forces compressed air out through the discharge port.
This continuous compression process eliminates sudden air release, significantly reducing pressure pulsation and noise.
Quality in Every Step
Precision Machining
In-house 5-axis CNC machining with micron-level precision for core components.
Testing Center
Every blower undergoes rigorous performance, noise, and vibration testing before shipment. 100% reliable.
