Explore our certified high-performance formulation array, built to optimize thermal performance and improve water-separation efficacy under high load.
In modern industrial setups, a compressed air system is a key energy source. When atmospheric air is compressed, massive quantities of moisture accumulate, forming condensed water droplets. A water separator kompresor is designed to mechanically extract this moisture from the air line. However, the internal compressor oil is exposed to high temperature, pressure, and this condensed water.
If the air compressor oil has poor water-separation properties, it will emulsify. This emulsification breaks down the fluid’s load-carrying capacity, resulting in critical component wear, oxidation, sludge deposition, and clogged separator elements. At Shandong Longhai Lubrication Technology, our engineering focuses on the demulsibility property (ASTM D1401) of compressor lubricants, allowing rapid separation of water from the oil, ensuring the mechanical water separator handles clean water while the compressor oil remains uncontaminated.
Rapid separation of water from oil limits acid creation, preventing corrosion in high-humidity screw compressors.
Advanced synthetic formulations minimize carbon deposits on mechanical water separator baffles.
Maintains dynamic viscosity at continuous operating temperatures exceeding 100°C.
Established in 2009 and based in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech pioneer with 15+ years of focus on high-performance lubricant formulation, smart factory manufacturing, and international B2B lubrication solutions.
Spanning over 131 acres with an annual production yield exceeding 200,000 tons, our facility integrates fully automated blending systems and precision filling lines. Through state-of-the-art metering methods, we guarantee a volumetric precision of 1‰-2‰, improving our baseline operational throughput by 20% to 35%.
Every year, Longhai channels over 5% of its total revenue back into R&D. Collaborations with universities and institutes ensure our products perform reliably in harsh environmental states. Our brand "Century Longhai" and strategic British "A Ba" range are fully backed by PICC (China People's Insurance Company) for operational peace of mind.
To assist global procurement managers in reducing Total Cost of Ownership (TCO), we provide custom lubrication frameworks engineered for challenges in high-humidity compressor systems.
High temperatures and ambient dust require oils that maintain thin-film strength and allow the water separator to purge particulate slurries without oil foaming.
Silicon and microchip manufacturing need oil-free air. Our synthetic compressor oils keep moisture separation at peak efficiency, preventing downstream vapor crossover.
Corrosive vapor environments lead to rapid oxidation. Our lubricants use specific rust inhibitors that protect raw surfaces, even when in contact with acidic water condensate.
Over the next five years, our technological roadmap focuses on biodegradable esters and polyalkylene glycols (PAGs) to support eco-conscious B2B operations. Traditional mineral base oils struggle in continuous, high-intensity moisture conditions. By optimizing base structures, we can extend the service lifespan of our compressor oils from 2,000 hours to over 8,000 hours, even in saturated environments. This reduces chemical waste and helps operators hit strict ESG goals.
Shandong Longhai complies with international quality metrics. Our standardizations provide absolute reliability to global B2B procurement partners.
Our production base holds certifications for ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018. This ensures every batch of air compressor lubricant or transmission fluid matches global standards, minimizing mechanical breakdowns under harsh industrial stresses.
From viscosity adjustments to customized chemical formulations, our lab coordinates closely with equipment builders to achieve exact requirements.
Analyzing temperature parameters and moisture extraction requirements.
Blending specific base fluids with demulsifiers and anti-wear agents.
Verifying water separation speeds in simulation trials.
Executing large-scale automated filling and quality control checks.
Whether you are building standard rotary screw compressors, piston compressors, or massive centrifugal installations, we can adjust the formulation profile. Our options include full-synthetic, semi-synthetic, or high-refinement mineral bases to target the exact operating parameters of your equipment line.
Furthermore, we provide complete downstream support, including customized packaging design, chemical documentation, compliance files, and fast shipping to your assembly centers.
Explore our clean manufacturing zones, fully automated bottling lines, and technical laboratory testing centers.
Industrial operations in Europe (EU), North America, and Southeast Asia face differing regulations regarding safety and sustainability. In the EU, chemicals must comply with strict REACH guidelines. For operations using open exhaust designs, biodegradable and non-toxic lubricants are frequently required.
Our technical support team helps procurement managers choose products that match local regional standards, including RoHS, GB China Standardizations, and DIN Germany. This ensures your compressor systems can operate globally without regulatory bottlenecks.
Located near major shipping ports in Shandong, we provide fast delivery routes for bulk liquid containers, intermediate bulk containers (IBCs), and standard 200L drums. Our logistics department handles customs processing, bulk certifications, and freight booking to streamline your supply chain.
Find answers to common technical questions about air compressor water separators, lubrication design, and factory supply options.
Air compressors generate large volumes of condensation during compression. If the oil cannot separate from this water quickly, it forms a thick emulsion. This emulsion lacks the strength to protect moving parts, leading to high wear, oxidation, and clogged mechanical separator filters.
This depends on the oil base. Standard mineral oils last between 2,000 and 3,000 operating hours. Advanced synthetic formulations (such as PAOs or esters) can last 8,000+ hours under normal operating temperatures. We recommend regular oil analysis to monitor viscosity and water content.
Yes. We have a dedicated laboratory to customize viscosity, pour points, and additive packages (such as extra anti-wear or demulsifying properties) to match your specific hardware designs and regional operating climates.
Our production facilities operate under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 guidelines. We also hold OEM approvals, such as Mercedes-Benz fluid approval, guaranteeing consistent product quality batch-after-batch.
We do not recommend mixing different types of lubricants. Mixing mineral and synthetic oils can degrade additive performance, leading to foaming, poor water separation, and deposit buildup. Always perform a complete system flush before switching to a new oil formulation.
