British-Owned Air Solutions Authority Since 2004
Established in the industrial manufacturing hub of Jiading District, Shanghai, Shanghai Honest Compressor Co., Ltd. stands as a premier enterprise specializing in the design, optimization, and large-scale fabrication of high-efficiency twin-screw air compressors. Over the past two decades, we have evolved into a global supplier of complete compressed air systems, helping facilities cross-engineer highly reliable air dryer compressor setups.
Our expansive production envelope delivers complete industrial packages—spanning low, medium, and high-pressure oil-free screw air systems, integrated dryer configurations, gas separation plants, ceramic membrane filtration arrays, and desiccant dryers. Fully certified under the ISO 9001:2015 Quality Management System, every unit undergoes exhaustive load-testing at our National Compressor Inspection Center to verify energy metrics that consistently outperform national energy-saving standards.
Why atmospheric treatment and water elimination determine system efficiency and machine life-cycle costs.
Ambient air contains significant vapor. During compression, this moisture concentrates. Untreated liquid water corrodes steel pipelines, washes away critical lubrication in downstream pneumatic cylinders, and ruins high-precision instruments. An integrated dryer stops corrosion before it begins.
Water collection in distribution loops creates localized blocks and high differential pressures. To maintain terminal pressure, operators often over-pressurize the compressor. Eliminating moisture prevents pressure drops, saving up to 15% in specific power consumption.
For applications such as food processing, medical systems, and fiber laser cutting, residual moisture causes product contamination or cutting dross. Systems integrated with premium desiccant or refrigerated dryers ensure compliance with ISO 8573-1 air classes.
"Under standard working conditions of 30°C and 75% relative humidity, an unmanaged 75kW air compressor can introduce more than 100 liters of liquid water into a production loop daily. Our integrated design acts as a dual-action thermal wall to drop dew points and extract vapor prior to air export."

How Shanghai Honest Compressor integrates permanent magnet motors, advanced cooling circuits, and dual-stage airends.
Our VSD PM systems utilize high-coercivity NdFeB permanent magnets that retain magnetic properties beyond 180°C. Compared to standard asynchronous motors, these motors run with zero slip loss and achieve 96% operational efficiency across a broad speed range. By matching air production to real-time consumption, we eliminate idling energy losses and prevent system pressure spikes.
Traditional setups require piping between the compressor, wet air receiver, pre-filters, refrigerated dryer, post-filters, and dry air receiver. Our ODM integrated solutions house the screw compressor, refrigeration circuit, and filtration blocks in a single, sound-insulated enclosure. This reduces the layout footprint by up to 45% and eliminates internal piping pressure drops, lowering total specific power requirements.
In high-power fiber laser cutting, auxiliary gas pressure must be consistent and dry. Our 20-bar specialized packages incorporate dual-stage oil separation filters and desiccant dryers. This setup prevents trace oil or moisture droplets from contaminating expensive protective optics and ensures a clean, dross-free edge profile on thick-plate stainless steel and aluminum.
For operations demanding sub-zero dew points (e.g., -40°C PDP), we supply Micro-Heat Regeneration Desiccant Dryers. By heating a small stream of dry purge air (typically under 5%), these dryers regenerate desiccant beds faster and more efficiently than heatless designs. This maintains stable dew points and minimizes purge air loss, keeping system pressures steady.
Industrial settings expose compressors to ambient heat, dust, and corrosive vapors. Our units feature epoxy-coated condenser fins, stainless steel moisture separators, and automated, zero-loss float drains. This ensures reliable performance in ambient temperatures up to 46°C, protecting your downstream pneumatic investments.
Solving demanding moisture and contamination challenges across global industrial applications.
At pressures up to 20 bar, trace moisture or oil in the auxiliary air stream will vaporize under the laser beam, clouding the lens and causing cutting defects. Our integrated 20-bar screw air systems supply clean, dry air to protect optics and deliver consistent cutting quality.
Process air must be dry and oil-free to prevent bacterial growth and product contamination. We utilize 100% water-lubricated oil-free screw technologies coupled with desiccant dryers to deliver clean air for mixing, packaging, and sorting applications.
Water droplets in paint spray systems can cause surface blemishes, while wet air leads to corrosion in pneumatic assembly tools. Our direct-drive VSD PM systems with integrated dryers ensure smooth, continuous air delivery for consistent paint finishes.
Technical answers to key selection, design, and integration questions for industrial users.
An integrated unit consolidates the compressor, dryer, and filtration systems inside a single enclosure. This reduces external installation space, minimizes piping costs, and eliminates pressure drops between separate components. Additionally, unified control systems monitor both the compressor and the dryer for balanced energy efficiency.
In a VSD PM system, motor speed changes dynamically to match real-time demand. This keeps air velocity through the heat exchanger and moisture separator constant, allowing the integrated dryer to run at stable thermal loads and preventing moisture carryover during rapid demand shifts.
Our integrated refrigerated dryers achieve a Pressure Dew Point (PDP) of +3°C to +10°C, suitable for standard manufacturing. For applications requiring drier air, our micro-heat desiccant dryers can be added to lower the dew point down to -40°C or -70°C, meeting ISO 8573-1 Class 1 standards.
Yes. As an ODM supplier and factory, we customize systems to meet local industrial standards worldwide. This includes voltage ratings (e.g., 220V, 380V, 415V, 460V at 50Hz/60Hz), dual-stage compression configurations, oil-free designs, and extreme-ambient cooling modifications.
Water-lubricated screw air compressors use pure water for lubrication, sealing, and cooling. This provides true ISO Class 0 oil-free air while keeping discharge temperatures lower than dry oil-free compressors, reducing thermal stress and improving overall thermodynamic efficiency.
We provide full documentation, remote troubleshooting support, and a comprehensive stock of spare parts (e.g., replacement cartridges, desiccant beads, sensors). In regions with local partner networks, onsite commissioning, training, and maintenance services are also available.
