Shanghai Honest Compressor Co., Ltd. is a British-owned enterprise founded in early 2004. Headquartered at NO. 355 Jiajian Branch Road, Malu Town, Jiading District, Shanghai, China, we have grown into a leading manufacturer of twin-screw air compressors and an important supplier of integrated air system solutions.
Our comprehensive production portfolio spans piston air compressors (low, medium, and high pressure, as well as dry oil-free units), rotary screw air compressor systems (ranging from 3kW to 480kW), industrial gas separation equipment, refrigerant compressors, cold dryers, precision filters, ceramic membrane filtration systems, and genuine consumables. By fusing British engineering standards with local supply chain efficiencies, we supply reliable air systems worldwide.
Deploying thermodynamic engineering and aerodynamic profiles to optimize industrial compressed air generation.
The core of our twin-screw compressor relies on a 5:6 asymmetrical rotor profile. This configuration reduces blow-hole leakage pathways and minimizes internal backflow, sustaining higher volumetric efficiency even at lower rotational speeds. Ongoing research focuses on nano-material rotor coatings that mitigate thermal wear and expansion under continuous duty.
By coupling permanent magnet (PM) motors with Variable Speed Drives (VSD), our systems bypass traditional transmission losses. The oil-cooled design allows the motor to utilize the compressor's cooling loop, maintaining low operating temperatures and preventing demagnetization, even when operating at a 15% speed turndown ratio.
For applications requiring absolute purity, our water-lubricated oil-free rotary screw compressors replace standard lubricating oil with pure water. This design seals, lubricates, and cools the compression chamber, ensuring Class 0 certified oil-free air without the risk of synthetic fluid carryover.
Custom-engineered configurations tailored to meet the air purity and volume requirements of major industrial sectors.
Delivering stable, moisture-free compressed air at pressures up to 15.5 bar. This ensures clean, dross-free edge cuts when processing thick stainless steel and carbon steel plates.
Utilizes Class 0 dry oil-free air compressors and ceramic membrane filtration to safeguard packaging and production lines from oil aerosols and microbiological contamination.
Designed for continuous operation in harsh, dusty conditions, these units feature heavy-duty air intake filters and robust direct-drive configurations that withstand vibration.
High-flow, low-pressure screw blowers supply continuous displacement air for dry bulk powder transport, lowering energy use compared to high-pressure systems.
Our manufacturing facility in Jiading, Shanghai, operates under computerized assembly and testing protocols to ensure high quality and consistency across our product lines.
By sourcing raw castings, permanent magnet stators, and key mechanical components within the Yangtze River Delta industrial cluster, we optimize production speed and quality control. Every machine undergoes a full-load factory test run before shipment to verify thermal stability, vibration metrics, and specific power consumption under simulated field conditions.
