Inverter
The inverter is the brain of the air compressor, and all operations of the air compressor are processed and regulated through the inverter, ensuring the safe and reliable operation of the air compressor system in all aspects.
We typically use inverters from Megmeet, Inovance, and Zoncn, which are internationally renowned brands with stable and reliable quality and guaranteed after-sales service, providing customers with the best possible air compressor user experience.
Controller
- Adopts PLC multilanguage control system with a beautiful and intuitive interface, easy-to-operate functions — operators can quickly and easily adjust the compressor.
- 14 protection functions including overload protection, short circuit protection, reverse protection, low temperature protection, high voltage protection, and more to fully protect the unit.
- Advanced microcomputer control drive system realizes intelligent control, air volume variable speed control, automatic adjustment of load start and soft start. Dynamic display of working status, visual pressure, temperature, and current working curves.
- Large memory equipped with printer interface; supports computer remote monitoring or multiple linkage control between air compressors.
Motor
- The main motor is an IP23 high-efficiency energy-saving permanent magnet motor carefully selected according to the application of the air compressor. (Other IP levels available.)
- All meet the national energy efficiency standards, F-class insulation, B-class temperature rise, effectively preventing the entry of dust.
- SKF heavy-duty bearings ensure continuous trouble-free operation for a long time.
Air-end
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, the Baosi air-end helps improve overall compressor efficiency, reduce energy consumption, and ensure consistent compressed air supply for various industrial applications.
Air Dryer and Precision Filter Set
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 by cooling air 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 — suitable for various industrial applications requiring clean and dry compressed air.
