China Suppliers Two-Stage Screw Air Compressor Factory - Energy Efficient, Durable, and High-Performance Solutions

Introducing our Two-Stage Air Compressor, a state-of-the-art solution designed for maximum efficiency and reliability. This compressor utilizes advanced dual-stage compression technology, making it significantly more efficient than traditional single-stage compressors. By implementing two-stage compression, our system approaches the principles of isothermal compression, achieving energy savings of 5-8%. This is made possible through the injection of fresh oil between stages, which lowers the inlet temperature of the second stage and optimizes performance, Key features of our Two-Stage Air Compressor include:, ● Innovative variable speed technology developed in-house, enhancing efficiency and promoting cost-effective energy savings, ● Options for SKF Bearings and GHH RAND / Rotor Comp Air End for superior performance, ● Improved stability and reliability, ensuring you receive the best value from our products, ● A remarkable reduction in power consumption of approximately 35% compared to traditional frequency machines, Whether you operate in industrial manufacturing, construction, or energy production, our Two-Stage Screw Air Compressor is the ideal choice for your needs. With precise control, efficient energy utilization, and exceptional durability, it enables you to streamline production while significantly reducing energy consumption. As a leading supplier and manufacturer in China, we are committed to providing high-quality solutions that drive operational efficiency and sustainability for your business

    Details
    Air-end
    🏆 Level 1 Energy Efficiency Certified
    Two-stage compression tends toward isothermal compression — the most energy-efficient approach. Compared to single-stage compression, two-stage compression saves 5–8% energy. Compared to Level 2 Energy Efficiency Grade: saves 10%–15%. Compared to Level 3: saves 20%–30%.
    • Adopts two-stage independent compression.
    • Equal pressure ratio over both stages with lower compression speed, improving volumetric efficiency.
    • Oil mist spray cooling between stages keeps the compression process close to isothermal, improving insulation efficiency.
    • Two-stage rotors are directly driven by bevel gears, ensuring high transmission efficiency.
    • Large diameter, low-speed rotors reduce bearing stress, extending the lifespan of bearings and other components.
    Controller

    Frequently Asked Questions
    Q What is the advantage of two-stage compression over single-stage compression?
    Two-stage compression approaches isothermal compression, which is the most energy-efficient method. It saves 5–8% energy compared to single-stage compression, and depending on the energy efficiency grade comparison, can save up to 20–30% energy.
    Q What energy efficiency certification does the air-end hold?
    The air-end has won the Level 1 Energy Efficiency Grade Certification — the highest level — saving 10–15% energy over Level 2 and 20–30% over Level 3 efficiency grades.
    Q What type of controller is used in the air compressor?
    The air compressor uses an LCD HD touch monitor with PLC control and a human-friendly menu interface. It can display multiple operational parameters simultaneously and provides easy access to historical records for convenient maintenance.
    Q Which inverter brands are used, and why?
    We use inverters from Megmeet, Inovance, and Zoncn — all internationally recognized brands known for stable, reliable quality and strong after-sales service, ensuring the best possible user experience for air compressor operation.
    Q What are the key features of the motor used in the air compressor?
    The motor is an IP55 high-efficiency permanent magnet motor meeting national energy efficiency standards. It features F-class insulation, B-class temperature rise, effective dust protection, and SKF heavy-duty bearings for long-term trouble-free operation. Other IP levels are also available upon request.
    Q How does the two-stage rotor design benefit the air compressor's longevity?
    The large-diameter, low-speed rotors in the two-stage design significantly reduce stress on bearings and other mechanical components. This leads to a longer lifespan for bearings and related parts, reducing maintenance frequency and overall operating costs.
