China Two-stage Screw Air Compressor Factory - Energy-efficient Air Compression Solutions from Reliable Suppliers

Introducing our advanced Two-Stage Air Compressor, designed to optimize air compression with superior energy efficiency. Unlike traditional single-stage compressors, our two-stage technology approaches isothermal compression principles, resulting in energy savings of 5-8%. This is achieved through the injection of fresh oil between the compression stages, lowering the inlet temperature for the second stage. The reduced compression ratio enhances efficiency, while significantly minimizing rotor seal leakage, leading to exceptional volumetric performance, Key features of our Two-Stage Air Compressor include:, - Self-developed variable speed technology that maximizes efficiency and reduces energy consumption, - Optional high-quality components such as SKF bearings and GHH RAND/Rotor Comp air ends for enhanced durability, - Improved stability, reliability, and cost-effectiveness, - A remarkable 35% reduction in power consumption compared to traditional frequency machines, Our Two-Stage Air Compressor is ideal for various applications, including industrial manufacturing, construction, and energy production. As a leading supplier from China, our factory ensures the highest standards of quality and performance. Experience precise control, efficient energy utilization, and long-lasting durability, empowering you to increase production efficiency and achieve significant energy savings for your operations. Choose our Two-Stage Air Compressor to elevate your processes and drive your success forward

    Air-end
    ★ Won the Award of Level 1 Energy Efficiency Grade Certification
    Two-stage compression compared to single-stage compression — the two-stage compression tends toward the most efficient isothermal compression. From the principle, two-stage compression saves 5–8% more energy than single-stage compression.
    Compared with Level 2 Energy Efficiency Grade: saves 10%–15% energy. Compared with Level 3 Energy Efficiency Grade: saves 20%–30% energy.
    Adopt two-stage independent compression.
    The pressure ratio is equal over both stages as well as having a lower compression speed, which helps improve volumetric efficiency.
    Oil mist spray cooling is used between the stages to make the entire compression process close to isothermal compression and improve the compression insulation efficiency.
    The two-stage rotors are directly driven by the bevel gear respectively, and the compression transmission efficiency is high.
    The large diameter and low speed of the rotors reduce stress on the bearings, thus lengthening their life span as well as any other components.

    Frequently Asked Questions
    QWhat is the main advantage of two-stage compression over single-stage compression?
    Two-stage compression approaches isothermal compression more closely than single-stage compression, resulting in energy savings of 5–8%. With Level 1 Energy Efficiency Grade Certification, it can save 20%–30% energy compared to Level 3 efficiency systems.
    QWhat type of controller does this air compressor use?
    The air compressor features an LCD HD touch monitor with PLC control and a human-friendly menu interface. It can display multiple lines of operation parameters and historical records, making operation, inquiry, and maintenance simple and convenient.
    QWhich inverter brands are used, and why are they chosen?
    We typically use inverters from Megmeet, Inovance, and Zoncn — all internationally renowned brands known for stable and reliable quality and guaranteed after-sales service. These inverters act as the brain of the air compressor, processing and regulating all operations to ensure safe and reliable system performance.
    QWhat are the key specifications of the motor used in this air compressor?
    The main motor is an IP55 high-efficiency energy-saving permanent magnet motor (other IP levels are available upon request). It features F-class insulation, B-class temperature rise, and SKF heavy-duty bearings — all designed to prevent dust ingress and ensure long-term, trouble-free continuous operation.
    QHow does the two-stage air-end extend component life?
    The large-diameter, low-speed rotors in the two-stage air-end significantly reduce stress on bearings and other components. Combined with oil mist spray cooling between stages, the system operates at lower temperatures and mechanical stress, effectively extending the lifespan of all internal components.
    QIs this air compressor suitable for energy-efficiency compliance requirements?
    Yes. This air compressor has won the Level 1 Energy Efficiency Grade Certification — the highest level of energy efficiency recognition. It saves 10%–15% energy compared to Level 2 systems and 20%–30% compared to Level 3 systems, making it an excellent choice for facilities with strict energy compliance or sustainability goals.
