Ultra-efficient Double-stage Diesel Portable Air Compressor

Ultra-efficient Double-stage Diesel Portable Air Compressor Design Philosophy:


The energy-saving double-stage portable air compressor, as the leading of China’s energy-saving portable air compressor, is committed to provide the more economical, energy-saving and efficient portable air compressors.

It provides high standards of productions and services for oil and gas exploration, pipeline construction, mine drilling and explosion, water well drilling, sand mining and dredging, and infrastructure construction, etc. The portable air compressor adopts high-compression efficiency energy-saving double-stage screw air end, powerful brand engine, efficient cooling system, and reliable control system, to provide the superior performance!

Ultra-efficient Double-stage Diesel Portable Air Compressor Design Philosophy

Design Philosophy of High-efficiency and Energy-saving Products:

Achieve the best energy saving effect, could reduce up to 30% oil consumption.
Application strategy of compressor products: Reduce operating costs!!!

During the entire service life of the diesel engine portable air compressor, the operating cost takes up to 80% of the total cost. Reducing the cost of oil cost is decisive for reducing the overall cost. Therefore, clients paying more attention on reducing the operating cost of products

Ultra-efficient Double-stage Diesel Portable Air Compressor Cost

Gross cost = initial investment(purchase) cost + operating (fuels) cost+ maintenance cost.

Advantages of the Two-stage Compression:

  • Compared with single-stage compression, lower working temperature, and it tends to isothermal compression, energy saving reach to 8%.
  • Lower compression ratio, reduce internal leakage, volumetric efficiency is increased by 5-10%.
  • It is good to adjust each stage rotor speed to reach the optimum line speed range of 25-35m/s, in order to achieve the highest compression transfer efficiency.
