Two Stage Air Compressor

Two stage Screw Air Compressor

Our Two Stage Air Compressor employs advanced dual-stage compression technology to elevate air compression to higher pressures. This sophisticated design ensures not only enhanced energy efficiency and reduced energy consumption but also delivers stable airflow outputs for your processes and more consistent outlet temperatures.

Whether in industrial manufacturing, construction, or energy production, our Two-Stage Screw Air Compressor caters to your needs. Offering precise control, efficient energy utilization, and enduring durability, it empowers you to achieve more efficient production and significant energy-saving benefits for your operations.

Compared to single-stage compressors, a two-stage is much closer to isothermal compression. This is achieved by the injection of fresh oil between the stages which reduces the inlet temperature to the second stage. This lower inlet temperature increases efficiency by reducing the compression ratio between the stages. In addition, leakage between the rotor seals is significantly reduced resulting in outstanding volumetric efficiency.

  • Two-stage air compressors are closer to the ideal isothermal compression
  • Reduced leakage increases volumetric efficiency
  • Saves 10-15% of energy compared to single-stage compressors
  • Increases flow by 10-15% compared to single-stage compressors
  • Lower pressure differential increases efficiency and reliability
  • Low heat load
  • Easy maintenance and service
  • Lowest life cycle cost of any compressor on the market

  • Air end

The two-stage compression main engine is adopted, that is, the first-stage compression rotor and the second-stage compression rotor are combined in one casing, and are directly driven by helical gears respectively. Natural air enters the first stage of compression through the air filter, and is mixed with a small amount of lubricating oil in the compression cavity, and the mixed gas is compressed to the interstage pressure at the same time. The compressed gas enters the cooling channel and contacts with a large amount of oil mist, thereby greatly reducing the temperature. The cooled compressed gas enters the second-stage rotor, undergoes secondary compression, and is compressed to the final exhaust pressure.

  • Motor

A motor in which the rotor is rotated by the magnetic field generated by the alternating voltage associated with the stator coils and the magnetic force of the field. The permanent magnet synchronous motor adopts high-performance NdFeFeB permanent magnets, which will not lose magnetism at 120 °C. The high-quality elastic coupling is used for direct transmission, and the permanent magnet motor is integrated with the host of the compressor. The structure is more compact, and the transmission accuracy and efficiency are higher.

  • Oil and gas separator

Super large capacity oil and gas separator, superior quality oil and gas separation elements and gas and liquid filter elements, together with advanced three-time oil and gas separation technology, the oil content is controlled below 3ppm to ensure the high quality of compressed air.

  • Intake valve

Advanced air intake valve design, air intake adjustment range 0-100%, capacity adjustment valve adjustment, small pressure loss, stable action, long life

  • Oil filter

The spin-on oil filter with high-end aviation materials is used, and the effect is 20% higher than that of conventional filter elements, effectively prolonging the normal service life of the main engine.

  • Air filter

The air filter adopts a design with high dust holding capacity and low flow resistance, which can filter tiny solid particles in the air, and the dust removal effect can reach 99.5%, ensuring the normal operation and economical service life of each component of the system.
