Shanghai Honest Compressor Co., Ltd. is a British-owned enterprise. It was founded in early 2004. The production address is located at NO. 355 Jiajian Branch Road, Malu Town, Jiading District, Shanghai, China. It is a large-scale manufacturing enterprise specializing in the production of twin-screw air compressors in China. At the same time, It is also an important supplier of air system solutions.
We provide various types of piston air compressors (low pressure, medium pressure, high pressure, oil-free air compressors), screw air compressor systems (3KW-480KW various screw air compressors, gas separation equipment, refrigerant compressors, cold dryers, filters, ceramic membrane filtration systems) and various equipment accessories and consumables.
We fully implement strict management throughout the entire manufacturing process, strictly monitor product quality and environmental protection, and the company has passed ISO9001:2015 quality management system.
We pay attention to market trends in technology research and development, close to the needs of users, actively absorb the advantages of domestic and foreign brand performance structures, and integrate our own features of convenient maintenance, so that the air compressors we produce have more perfect structures, better performance, and energy saving and consumption reduction.
Obviously, after the test of the National Compressor Inspection Center, the energy consumption data is superior to the national energy-saving standard, and can provide users with various series of 3kW--480kW, air-cooled and water-cooled screw air compressors with a flow rate of 0.5m³/min-75m³/min. There are multiple models and categories of machines for users to choose from, as well as permanent magnet variable frequency air compressors, oil-free machines, mobile air compressors, etc., and can provide a complete set of construction plans for air compressor stations with design and manufacturing, user training, and service. The ability to support and host a complete set of service items such as overhaul.
B2B procurement teams prioritize total cost of ownership (TCO) rather than just initial purchase price. In critical industries like mining, deep-well drilling, pipeline pigging, and municipal construction, downtime can cost thousands of dollars per hour. Sourcing teams evaluate equipment based on three core parameters:
Energy accounts for over 70% of a compressor's lifecycle cost. Modern designs must use premium air ends, permanent magnet motors, and two-stage compression to maximize Free Air Delivery (FAD) per kilowatt consumed.
Compressors must operate in environments ranging from desert heat (50°C) to high-altitude mine sites (exceeding 3,000 meters above sea level) with heavy airborne dust.
Modular configurations, accessible oil-air separator cartridges, spin-on oil filters, and local aftermarket support ensure rapid service turnarounds.
Procurement managers also consider engine emission compliance, such as US EPA Tier 4 Final, EU Stage V, or corresponding national standards in China and the APAC region. Purchasing from an ISO9001:2015 certified manufacturer like Shanghai Honest Compressor ensures that manufacturing quality, metallurgical integrity, and testing procedures meet international standards.
Compressed air systems operate across various industries, each demanding distinct pressure ranges, purity levels, and flow profiles:
Rotary screw engineering has shifted from basic fixed-speed belt-drive systems to highly engineered direct-drive designs. Key technological advancements include:
Instead of compressing air to the target pressure in a single stage, two-stage compression splits the work between two serial rotors. Inter-cooling between stages lowers the air temperature, bringing the compression process closer to isothermal conditions. This design reduces internal backflow leakage and lowers the pressure ratio per stage, saving up to 15% in energy consumption.
Conventional induction motors experience rapid efficiency drops when operating at partial loads. Permanent Magnet Synchronous Motors (PMSM), paired with variable frequency drives, maintain high motor efficiency (IE4/IE5 equivalent) across their entire speed range. The system constantly matches motor RPM to actual air demand, eliminating idle energy losses.
Achieving residual oil content below 3ppm is crucial for downstream equipment. Modern separation systems use multi-stage mechanical impaction, gravity settling, and coalescing filtration elements to clean the air before it exits.
Shipping industrial equipment globally requires compliance with regional safety and quality standards. Shanghai Honest Compressor Co., Ltd. ensures compliance through a robust quality assurance system:
Our production lines follow ISO9001:2015 standards, ensuring complete traceability from raw casting inspection to the final FAD testing phase. Our pressure vessels are designed, built, and tested according to international boiler and pressure vessel codes, preventing mechanical failures under high operational temperatures and pressures.
To facilitate direct customer communication, we maintain a national free service hotline (400-705-9168) and support an expansive network of branches and local dealer service teams. This network provides rapid parts delivery, preventative maintenance, and complete overhaul support for our B2B customers.
