Product Description

Why choose a rotary screw compressor?
A rotary screw compressor is chosen for its high energy efficiency, continuous operation capability, compact design, low noise levels, longevity with proper maintenance, high output and capacity for various applications, consistent air quality, easy maintenance, adaptability to different requirements, and the option for both oil-lubricated and oil-free versions to meet specific application needs, making it a versatile and reliable choice for industrial and commercial applications.

What are the benefits of a lubricated compressor?

Extended Lifespan: Lubricated compressors are known for their longevity due to the presence of oil in the compression process. The oil helps reduce friction and wear on moving parts, resulting in a longer operational lifespan when properly maintained.
High Performance: These compressors can provide consistent and reliable performance, delivering a steady supply of compressed air, which is crucial for various industrial applications.
Better Cooling: The oil in lubricated compressors helps dissipate heat generated during compression, which prevents the compressor from overheating and ensures continuous operation.
Improved Air Quality: Lubricated compressors often feature oil filtration systems that remove contaminants from the compressed air, leading to cleaner air output, which is essential in industries like food processing and pharmaceuticals.
Efficient Sealing: Lubricated compressors usually have better sealing mechanisms, reducing air leakage and improving overall efficiency.

Choose our screw air compressor for several compelling reasons:

Energy Efficiency: Our compressor saves an impressive 25%-35% more energy compared to conventional air compressors, thanks to state-of-the-art energy-saving technology.
Synergy of Frequency Converter and Permanent Magnet Motor: The harmonious pairing of a frequency converter and a permanent magnet motor maximizes energy efficiency, ensuring optimal performance and energy savings.
Leading in Energy Efficiency: With the robust support of air compressor frequency converters and permanent magnet motors, our system stands out as an industry leader in energy conservation.
Rapid Return on Investment: While variable-frequency air compressors may involve initial investment costs, the remarkable energy savings they provide mean you can recoup this additional expenditure within just 1 to 2 years.
