The Baosi air-end used in screw air compressors is known for its high efficiency, durability, and stable performance. Designed with optimized rotor profiles and precision machining technology, it ensures efficient air compression while minimizing internal leakage and energy loss.

The air-end delivers stable airflow and pressure, supporting continuous and reliable operation in demanding industrial environments. Its robust structure and high-quality materials contribute to low vibration, low noise levels, and long service life.

With its efficient compression performance and reliable operation, the Baosi air-end helps improve overall compressor efficiency, reduce energy consumption, and ensure consistent compressed air supply for various industrial applications.

The refrigerated air dryer and precision filter system integrated with the 4-in-1 screw air compressor ensures a stable supply of clean and dry compressed air. The refrigerated air dryer effectively removes moisture from compressed air by cooling it to a low dew point, preventing condensation and protecting downstream equipment.

The precision filter group further purifies the air by removing oil mist, dust particles, and other impurities. With multi-stage filtration, it significantly improves air quality and helps extend the service life of pneumatic tools and machinery.

This combination ensures reliable air treatment, stable system performance, and higher operational efficiency, making it suitable for various industrial applications that require clean and dry compressed air.
