Engineered for extreme performance, superior wear protection, and optimized energy efficiency.
In modern heavy industries, air compressors act as the "heartbeat" of manufacturing automation, pneumatic systems, and process lines. However, operating conditions have grown increasingly demanding. Today's compressors run at higher pressures, elevated temperatures, and longer cycle run-times. In this demanding scenario, the quality of the lubricant is not merely a maintenance consideration; it directly dictates system uptime and overall thermal efficiency.
Globally, the industry is transitioning away from standard mineral oils toward high-performance synthetic chemistry (primarily PAO, POE, and PAG formulations). This shift is driven by the need to combat system varnishing, oil carryover, and oxidation breakdown. As a leading manufacturer based in China, we leverage state-of-the-art chemical engineering and large-scale manufacturing structures to supply cost-effective, high-tier lubricants that meet or exceed international standards like ISO VG 32/46/68, API, and OEM specifications.
A fully certified, high-technology pioneer in premium lubrication solutions since 2009.
Our History & Capabilities
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication is a high-tech enterprise integrating R&D, production, blending, and international trade. With over 15 years of focus on high-temperature, high-pressure industrial oils, we have built a complete industrial chain system dedicated to providing premium lubrication solutions for the global industrial and transportation fields.
Longhai Technology operates under its proprietary brand "Century Longhai", along with its international strategic partnership brand, the British "A Ba" series. Our products are insured by PICC (People's Insurance Company of China) to guarantee safety, reliability, and technical liability coverage. Our catalog encompasses a wide range of fluids: diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission fluid, turbine oil, refrigeration oil, and premium air compressor lubricants.
Our commitment: "Dare to explore, innovate continuously, survive by quality, and promote development by efficiency."
Spread over 131 acres, our intelligent manufacturing base features automated production and blending lines that serve clients across 139 cities globally.
We reinvest over 5% of annual revenue back into industrial fluid R&D, keeping joint labs with top universities to pioneer additive chemistry and molecular stability.
Our fully automatic packaging lines utilize volumetric metering principles, reducing margin of error while raising throughput speeds by 20% to 35%.
Unlocking superior heat transport and anti-varnish parameters through molecular design.
Industrial air compressors subject lubricants to high shear forces, high oxygen exposure, and hot compression zones. Under these settings, standard API Group I and II mineral oils suffer rapid carbon chain shearing and thermal degradation. This leads to the formulation of varnish, sludge, and acidic byproducts.
PAOs offer outstanding low-temperature flowability, extremely high viscosity indexes, and minimal volatility. They are the ideal choice for rotary screw air compressors operating under fluctuating climates.
PAGs provide superior heat transfer capabilities and naturally dissolve varnish pre-cursors. When a PAG lubricant ages, it does not leave sticky residues behind, ensuring the heat exchangers and internal piping stay pristine.
Used as co-base oils to enhance the polar affinity of the fluid, boosting seal swell characteristics and wear protection on high-speed rotor bearings.
Providing flexible, high-precision customization for worldwide brands and equipment manufacturers.
Tailored synthetic and semi-synthetic additive packages to match specific climatic environments or custom OEM requirements.
Support for small-scale pilot runs to large-scale mass exports across multiple categories: compressor oils, gear oils, engine oils.
ISO 9001, 14001, and 18001 production compliance. Strict quality controls to supply MSDS, RoHS, and SGS validation documents.
Integrated private label design, packaging printing, technical datasheet generation, and safety compliance handling.
Demand Analysis
Evaluating system parameters, base oil requirements, and target margins.
Formula Dev
Customizing viscometric profiles and selecting critical additive packages.
Sample Testing
Strict lab assessments including ASTM test benchmarks (Foaming, ASTM D2272 oxidation).
Production
Batch blending followed by high-speed, high-accuracy automatic packaging.
After-Sales
Routine oil analysis support, logistics updates, and continuous optimization.
Longhai Technology operates in total compliance with domestic and global quality systems. Our facilities have passed ISO-9001-2015 (Quality Management), ISO-14001 (Environmental Safety), and ISO-18001 (Occupational Health). Additionally, our automatic transmission lubricants have obtained official Mercedes-Benz certification, establishing a foundation of trust.
In our quality control labs, batch testing is executed on every run. Critical tests measure viscosity at 40°C/100°C, viscosity index, flash point, pour point, water separability, and copper strip corrosion. This ensures that the finished lubricants can withstand extreme operating conditions, helping clients prevent unexpected downtime and lower system maintenance costs.
Matching lubricants to demanding application environments to optimize machinery performance.
Continuous-run rotary screw compressors require stable ISO VG 46 synthetic oils. These maintain a consistent sealing film between rotors, keeping gas compression rates high and operating temperatures low.
Reciprocating compressors handling hydrocarbon gases require chemically inert PAG or high-viscosity synthetic oils. These resist dilution by the process gas stream, avoiding premature wear.
For applications where compressed air may contact food products, we supply food-grade synthetic lubricants. These utilize food-safe base stocks to comply with international purity guidelines.
Answering critical engineering and sourcing questions regarding air compressor lubrication.
Providing stable lubrication properties under extreme pressure and temperature variations.
