In modern industrial manufacturing, compressed air and process gases are no longer viewed simply as utilities; they are critical carriers of energy and process security. The demand for reliable gas air compressor systems has shifted from basic pressure delivery to high-fidelity, energy-optimized solutions that align with the global transition toward smart manufacturing and decarbonization. As a prominent British-owned manufacturing entity based in Jiading District, Shanghai, we engineer our systems to meet the most rigorous standards of efficiency and durability.
Different industrial processes require distinct thermodynamic, structural, and control parameters. Our product portfolio is custom-engineered to provide tailor-made performance across various complex application landscapes:
High-power fiber laser cutting demands consistent, dry, and clean gas flow at 20 bar pressures. Any trace of oil or moisture can destroy delicate optics and ruin cutting edges. Our specialized 20bar systems integrate high-efficiency filtration and moisture removal directly into the compression cycle to deliver flawless operation.
For large-scale factory instrumentation and pneumatic supply networks, we offer massive 315kW and 480kW twin-screw configurations. Utilizing advanced two-stage thermodynamic profiles, these units minimize specific power consumption under continuous duty, reducing corporate carbon footprints and operating overheads.
Eliminating hydrocarbons from process air is non-negotiable in pharmaceutical fermentation, chemical synthesis, and cleanroom packaging. Our dry-type oil-free twin-screw designs ensure 100% oil-free gas delivery, certified to ISO 8573-1 Class 0 parameters.
To serve international contractors and engineering firms, our entire machinery portfolio conforms strictly to global directives. Whether your site requires CE markings for the European Economic Area, ASME code certification for pressure vessels, or specific IP55 electrical standards for hazardous environments, our engineering teams ensure full design verification and localized certification support.

Equipped with high-precision PLC control panels and automatic startup logic.
Optimal interstage cooling logic providing massive energy savings.
Understanding the internal engineering of modern compressor systems helps operators optimize their plant's power consumption. The specific energy consumption (SER) of our twin-screw setups is minimized through precision rotor profiles, advanced cooling layouts, and synchronous permanent magnet motor control.
When compressing gas over large pressure ratios, single-stage compression produces significant heat, leading to air expansion and volumetric inefficiency. Our two-stage screw air compressors solve this problem by dividing the compression ratio across two separate rotor pairs:
Unlike fixed-speed compressors that experience high current surges and vent excess air during low demand, our Permanent Magnet (PM) synchronous motors adjust speed in real-time. By tracking the factory's actual air demand down to the second, these motors avoid idle run cycles, significantly reducing wear and energy waste.
Aeration basins in municipal wastewater plants require high volumes of continuous air flow at low pressures. Using standard high-pressure screw compressors for this is inefficient. Our specialized oil-free PM VFD screw blowers (such as the EGV-132A-140) provide high flow at low discharge pressures (0.5 to 1.5 bar), delivering quiet, efficient operation for continuous aeration basins.
Shanghai Honest Compressor Co., Ltd. is a British-owned manufacturing enterprise founded in 2004. Located at NO. 355 Jiajian Road, Malu Town, Jiading District, Shanghai, China, our facility is equipped with state-of-the-art rotor milling machines, automated testing laboratories, and climate-controlled assembly areas. We specialize in producing energy-saving twin-screw air compressors and complete air treatment systems.
Our core offerings range from 3kW to 480kW configurations, covering oil-injected and dry oil-free models. We also manufacture essential air treatment equipment, including refrigerated and desiccant dryers, line filters, and industrial vacuum pumps.
According to MRFR analysis, the global 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 a steady compound annual growth rate. This upward trajectory highlights the global shift away from oil-sealed systems toward clean, dry vacuum designs. These designs protect process integrity in semiconductor manufacturing, chemical handling, and solar cell production, while eliminating environmental contamination risks.
A two-stage screw compressor reduces the pressure ratio across each individual stage. This decreases internal leakage and keeps compression temperatures lower, bringing the process closer to energy-efficient isothermal compression. For plants operating above 7.5 bar, two-stage units can save up to 15% in energy consumption compared to single-stage equivalents.
Refrigerated air dryers cool the compressed air to between +2°C and +10°C, causing vaporized moisture to condense so it can be drained away. This prevents liquid water from collecting in downstream piping, protecting pneumatic valves, tools, and finished products from corrosion and moisture damage.
PM VSD compressors use smart variable frequency controls to match motor speed directly to your plant's real-time air consumption. This eliminates wasteful unloading cycles and pressure drops, lowering overall energy bills by up to 30% compared to traditional fixed-speed units.
Industries like pharmaceuticals, food and beverage packaging, electronics manufacturing, and clinical laboratories require ISO 8573-1 Class 0 certified oil-free air. In these applications, even minor oil contamination can ruin entire production batches, damage sensitive components, or present health hazards.
