In the modern industrial landscape, compressed air is often referred to as the "fourth utility." However, it is also one of the most energy-intensive resources. As a leading OEM Double Stage Screw Compressor Supplier & Exporter, we recognize that the shift from single-stage to double-stage compression is not just a technical upgrade—it is a mandatory evolution for businesses aiming for carbon neutrality and operational excellence.
The core philosophy of a Two-Stage Screw Air Compressor lies in the division of the compression process. By utilizing two sets of rotors in series, the air is first compressed to an intermediate pressure, cooled via oil injection (intercooling), and then compressed to the final discharge pressure. This process reduces the work required for compression and enhances the volumetric efficiency of the machine.
Founded in early 2004, Shanghai Honest Compressor Co., Ltd. integrates British engineering standards with China's manufacturing agility. Based in Jiading District, Shanghai, we have evolved into a global titan in air system solutions.
We provide a comprehensive range of equipment, from piston compressors to high-end Double Stage Screw Compressors, gas separation equipment, and ceramic membrane filtration systems.
Fully implementing ISO9001:2015, we monitor every step of the manufacturing process to ensure environmental protection and superior performance that exceeds national energy-saving standards.
Original Company Overview: Shanghai Honest Compressor Co., Ltd. is a British-owned enterprise specializing in the production of twin-screw air compressors in China. Our production facility at NO. 355 Jiajian Branch Road, Malu Town, Jiading District, Shanghai, is an important hub for air system solutions. We pay attention to market trends in technology R&D, actively absorbing the advantages of domestic and foreign brand performance structures to ensure our compressors have perfect structures, better performance, and obvious energy-saving results.
Our Shanghai facility represents the pinnacle of Industry 4.0 in the compressor sector. By integrating automated rotor machining, IoT-enabled testing benches, and real-time supply chain monitoring, we offer unparalleled lead times and product consistency for global enterprises.
For international buyers, procurement goes beyond the machine itself. It involves rigorous compliance with regional standards such as CE (Europe), ASME (USA), and various energy efficiency certifications. As an experienced exporter, we provide:
Incorporating machine learning algorithms to predict bearing failures and oil change intervals before they happen, reducing downtime by 40%.
Next-gen Permanent Magnet motors achieving IE5 efficiency levels, maintaining high torque even at low RPMs for variable demand applications.
Expanding our screw technology into the hydrogen compression and carbon capture sectors to support the global energy transition.
A Double Stage Screw Compressor is not a one-size-fits-all product. We provide bespoke solutions tailored to specific industrial ecosystems:
High-volume, 24/7 operations requiring extreme durability. Our 110kw Two-Stage PM Inverter models are the gold standard here.
Our 100% Oil-Free Water Lubricated Screw Air Compressors ensure zero risk of contamination in sensitive production environments.
High-dust environments require superior filtration and cooling. Our oil-cooled permanent magnet series handles these harsh conditions with ease.
Mobile and stationary units capable of operating in extreme temperatures, providing reliable power for pneumatic tools and separation systems.
A: The primary ROI comes from electricity savings. Because each stage has a lower pressure ratio, the compression heat is reduced, and volumetric efficiency increases. Most industrial users see a payback period of 12-24 months purely from energy bill reductions.
A: VSD allows the compressor to match its motor speed exactly to the air demand. When combined with two-stage compression, it eliminates "unload" energy waste, which can account for 30% of energy use in traditional fixed-speed compressors.
A: Yes. We have a free service hotline (400-705-9168) and a global network of dealer service teams. We provide user training, design for air compressor stations, and host complete overhaul services to ensure 100% uptime.
A: Absolutely. As a British-owned factory in China, we specialize in tailoring machines for the global market, including various voltage inputs (220V/380V/440V/460V), explosion-proof requirements, and specialized cooling configurations for extreme climates.
A: Due to the reduced load on each rotor set, the bearing life is significantly extended compared to single-stage units. With proper maintenance, our air-ends are designed for over 100,000 hours of operation.
