Explore our cutting-edge, high-efficiency twin-screw and variable-frequency compressor products engineered for global industries.
Bridging European engineering rigor with China’s high-efficiency industrial supply chains to deliver unparalleled gas and air compression technology.
Founded in early 2004, Shanghai Honest Compressor Co., Ltd. is a British-owned enterprise operating out of a state-of-the-art manufacturing campus at NO. 355 Jiajian Branch Road, Malu Town, Jiading District, Shanghai, China. As a premier twin-screw air compressor manufacturing base, we serve as a strategic supplier of air and gas system solutions globally.
Our expansive production portfolio covers piston air compressors (low, medium, and high pressure, as well as oil-free solutions), complete screw air compressor systems (ranging from 3KW to 480KW), gas separation equipment, refrigerant compressors, refrigerated air dryers, inline filters, ceramic membrane filtration setups, and all corresponding consumables.
We operate in strict conformity with the ISO9001:2015 quality management system, implementing rigid control barriers across casting, machining, rotor balancing, assembly, and final performance verification.
Choosing the right equipment requires a clear understanding of aerodynamic design, pressure ranges, and thermodynamic efficiency.
Compressors are engineered to compress gases to high pressures (typically 3 bar up to 15.5 bar and beyond in screw systems) for stored energy applications. Air blowers focus on high-volume flow rates at lower discharge pressures (usually 0.3 bar to 1.5 bar) optimized for low-resistance processes like aeration.
Blowers generally operate with dynamic compression or positive displacement (using rotary lobes or high-efficiency screws). Compressors utilize tight internal compression profiles, necessitating precise lubrication, cooling cycles, or highly complex water-jacketed oil-free chambers.
Because low-pressure applications waste substantial energy when throttled down from high-pressure lines, using a designated screw blower instead of a standard air compressor for low-pressure gas tasks reduces electricity consumption by up to 35% to 50%.
How our Shanghai-based facilities translate geographical and economic benefits into high-value machinery for global buyers.
Our location in the Yangtze River Delta gives us immediate access to world-class steel fabrication, advanced motor winding providers, and high-precision CNC machining centers. This proximity cuts lead times and slashes component logistics costs.
Unlike Western plants with rigid configuration layouts, our engineering office provides customized modifications (such as special voltages, explosion-proof builds, marine-grade paints, and bespoke logic controllers) within fractions of the standard turnaround time.
Combining domestic casting efficiency with premium imported engineering parts ensures our machines match European performance metrics, while reducing initial capital expenditure (CAPEX) for the end client by 30% to 45%.
Providing reliable compressed gas and air flow across municipal, heavy industrial, and specialized processing lines.
Aeration tanks in modern water treatment facilities run continuously. Our oil-free VSD permanent magnet screw blowers ensure zero oil contamination reaches water beds, while operating reliably in high-humidity ambient settings.
Laser operations require dry, oil-free high-pressure air (typically 15.5 bar) to blow away slag and maintain clean cuts. Our dedicated 15.5 bar integrated screw compressors deliver consistent high-density air flow with low oil carryover.
In food, chemical, and cement processing, dry and reliable low-pressure air carries bulk powders through pipelines. Our low-pressure screw compressors (3 bar to 5 bar) prevent product clogging and minimize thermal degradation.
Stay ahead of the curve with insights from our engineering division regarding clean-air regulations and operational efficiency.
Global environmental regulations are driving a shift toward water-lubricated and oil-free screw machinery. In pharmaceuticals, electronics, and food packing, even trace oil molecules can ruin production batches. Oil-free permanent magnet VFD screw systems are transitioning from a premium alternative to a regulatory necessity.
Modern factories demand real-time machine telemetry. Our advanced controllers track discharge pressure, rotor temperature, vibration, and energy metrics. They feed this data to central SCADA systems and remote servers, shifting maintenance from reactive to predictive.
By dividing the compression ratio across two sequential rotors with inter-stage cooling, internal thermal losses drop significantly. This design brings the system closer to ideal isothermal compression, saving up to 15% more power compared to single-stage units of equivalent capacity.
Ensure long-term reliability and compliance when importing industrial air machinery from China.
