2. Customized bearings: Bearings are engineered for a lifespan of 120,000 hours, significantly reducing maintenance frequency.
3. Piston with imported molding technology: Advanced molding technology ensures excellent wear resistance, preventing performance degradation from deformation or damage.
4. Cylinder with Japanese coating technology: Specially coated cylinders provide low friction, extended service life, and enhanced efficiency.
5. Environmentally friendly oil free design: No lubricating oil required, guaranteeing cleaner compressed air—ideal for industries with high air quality demands.
6. High-efficiency permanent magnet synchronous motor: Equipped with an IE4 high-efficiency PMSM, N38UH-grade magnets, and IP67 protection for long-term stable operation.
7. Totally enclosed structure: Features a fully enclosed design with vacuum epoxy dipping paint treatment, enhancing protection and operational stability.

Working Principle

1. Suction process: The piston moves downward, reducing cylinder pressure and drawing in outside air through the inlet valve.
2. Compression process: The piston moves upward, compressing the air, increasing cylinder pressure and temperature.
3. Exhaust process: When the set pressure is reached, the exhaust valve opens and releases compressed air to a storage tank or directly to the application.

The oil free design, combined with precise engineering and advanced technology, ensures clean, contaminant-free air that will not affect downstream equipment or products.
