1. Exceptional Energy Efficiency

 

The QWL Series features a two-stage compression air-end, which significantly reduces the compression ratio compared to single-stage compressors. This design minimizes air leakage and lowers the temperature rise during operation, resulting in an impressive 15% energy saving. Additionally, it is equipped with an IE4 permanent magnet motor that boasts a 97% efficiency rating, providing an extra 5% energy reduction. Together, these features help businesses cut down on energy costs and reduce their environmental impact.

 

2. High Performance and Reliability

 

Built with precision and durability in mind, the QWL Series delivers consistent and reliable performance. The two-stage compression process ensures a stable discharge pressure, ranging from 0.4MPa to 1.6MPa, and a high air delivery rate, making it suitable for a wide range of industrial applications. The permanent magnet rotor is directly mounted on the male rotor's extension shaft, eliminating the need for motor bearings and reducing the risk of mechanical failure. This robust construction ensures a long service life of over 15 years, even under harsh operating conditions.

 

3. Versatile and Customizable

 

Quanwei Machinery understands that every business has unique needs. The QWL Series is available in power ratings from 4KW to 315KW, allowing for flexible selection based on specific requirements. It can also be customized to meet the demands of different climates and industries. Whether it's for a small workshop or a large industrial plant, the QWL Series can be tailored to provide the optimal compressed air solution. Furthermore, the integrated design, which combines the compressor, air dryer, air tank, and filters, saves space and simplifies installation and maintenance.
