View Technical Specs →In modern industrial manufacturing, the demand for high-reliability compressed air solutions has shifted from basic pressure delivery to high-fidelity, thermodynamic-efficient, and digitally controlled air systems. Lubricating compressors remain the backbone of heavy industries because of their superior heat dissipation, continuous duty cycles, and exceptional volumetric efficiency. A lubricating compressor utilizes specialized lubricants to seal clearances between rotary screw profiles or piston cylinders, reducing friction and absorbing heat directly at the point of compression.
Traditional single-stage compressors face severe thermodynamic limits when compressing air above 8 bar in a single stroke or rotation. This leads to high discharge temperatures and reduced volumetric efficiency. Two-stage compression resolves this problem by separating the compression process into low-pressure and high-pressure stages:
Fixed-speed compressors suffer from significant energy losses during unloaded operation. Our next-generation systems integrate Variable Frequency Drives (VFD) coupled with Permanent Magnet (PM) synchronous motors (conforming to IE4 and IE5 efficiency classes). PM motors maintain high torque and efficiency even at low rotational speeds, avoiding the winding losses typical of standard induction motors. When the plant's pneumatic demand fluctuates, the VFD system dynamically adjusts the rotor speed, maintaining constant discharge pressure within a ±0.01 MPa range. This prevents wasteful over-pressurization and eliminates venting cycles.
For international procurement managers, vetting a Chinese lubricating compressor manufacturer requires assessing specific technical benchmarks to ensure long-term operational stability and compliance with local safety standards.
Ensure the manufacturer provides valid CE certificates for Europe, ASME pressure vessel certificates for the United States, and UL/CSA electrical certification for control panels. Dual ISO 9001 and ISO 14001 compliance is standard for Tier-1 suppliers.
Industrial environments demand robust electrical enclosures. Look for motors rated at IP55 or IP54 with Class F or H insulation, protecting windings from fine dust, particulate ingress, and moisture.
Ask for asymmetric rotor profiles (e.g., 5:6 lobe combinations). Precision grinding of the rotor profile determines the volumetric efficiency and minimizes internal pressure drop.

See more products >A compressor does not operate in isolation. Peak plant performance requires designing an integrated air preparation system that matches specific application requirements. Our systems are engineered to address the distinct needs of several key sectors:
Fiber laser cutting requires dry, clean, high-pressure gas to blow away molten metal during processing. A standard 8-bar compressor cannot provide the necessary cut velocity or quality. Our special 15.5 bar screw air compressors are designed to support laser heads by preventing slag formation, maintaining clean cut edges, and protecting optical lenses from moisture and oil mist.
Explosion hazards, extreme dust, and high humidity are major challenges in mining environments. We build certified explosion-proof air compressors equipped with intrinsically safe PLC controls, IP55-rated flameproof motors, and heavy-duty intake filtration systems. These units operate reliably under constant vibrational stress and temperature fluctuations.
Chemical processing and pneumatic spinning lines require oil-free air to prevent product spoilage. By pairing our lubricating compressors with high-efficiency desiccant air dryers, multi-stage oil coalescing filters, and activated carbon adsorbers, we achieve residual oil levels below 0.01 mg/m³ and dewpoints down to -70°C, offering a cost-effective alternative to oil-free dry screw designs.
For operations with limited space or those requiring fast mobilization, our integrated 4-in-1 air stations combine the compressor, storage receiver, refrigerant dryer, and multi-stage filtration on a single structural skid. These pre-piped and pre-wired systems simplify installation, requiring only a single power connection and main air discharge link.
Shanghai Honest Compressor Co., Ltd. is a British-owned enterprise founded in early 2004. Located at NO. 355 Jiajian Branch Road, Malu Town, Jiading District, Shanghai, China, the company has grown into a major manufacturing center for twin-screw air compressors and complete air system solutions.
We supply a comprehensive range of pneumatic equipment, including piston air compressors (covering low, medium, and high-pressure ranges, as well as oil-free variants) and complete screw air compressor systems (ranging from 3KW to 480KW). Our portfolio also features gas separation equipment, refrigerant compressors, cold dryers, line filters, ceramic membrane filtration systems, and genuine replacement parts.
By blending British design standards with China's manufacturing capabilities, we deliver high-performance, energy-efficient compressed air systems that meet strict international standards.
According to MRFR analysis, the dry vacuum pump market size is valued at US$ 5.97 billion in 2024. The dry vacuum pump market is expected to grow from US$ 6.17 billion in 2025 to US$ 8.28 billion in 2034, registering key technology adoptions. Our research and development division tracks these developments to align our vacuum technologies and dry running screw configurations with international industrial needs.
