Engineered to deliver exceptional oxidation stability, anti-wear protection, and long service intervals under aggressive operational conditions.
Modern air compressors operate under increasingly demanding parameters: higher discharge pressures, elevated temperatures, and prolonged continuous runtimes. These extreme environments place severe chemical and physical stresses on the lubrication system. Industrial operations worldwide rely on compressors for pneumatic power, process gas recovery, and control systems. The degradation of compressor fluid is one of the primary drivers of mechanical failure, increased energy consumption, and high operational overheads.
In response to these challenges, Shandong Longhai Lubrication Technology Development Co., Ltd. has spent over 15 years developing advanced compressor fluids designed to mitigate thermal breakdown. High-efficiency air compressor oils must withstand intense shear stress and prevent the formation of carbon deposits and carbon-based sludge on discharge valves and intercoolers.
Through our proprietary base stock refining and synthetic blending operations, we deliver high-performance fluids that achieve remarkable demulsibility, ensuring rapid air-water separation and maintaining optimal film strength even under humid ambient conditions.
Detailed engineering parameters of our premium fluids and how they map to global industrial sectors.
Prevents the polymerization of oil molecules at high discharge temperatures. Reduces downstream filter plugging and valve sticking, extending drain intervals from 2,000 to over 8,000 hours under optimal configurations.
Formulated with advanced anti-wear (AW) additives to establish a resilient boundary film. Protects critical contacting surfaces of rotary screws and reciprocating cylinders from friction damage during startup.
Rapidly sheds condensate moisture to prevent water-oil emulsions. Fast air release reduces foaming risk, protecting system components from localized oil starvation and cavitation erosion.

How our products perform in major industrial ecosystems around the world.
Continuous-duty air compressors in chemical processing require maximum reliability. Our fluids protect high-output units against acid gas contamination and thermal degradation, reducing unexpected downtime.
Pneumatic assembly equipment demands clean, oil-free control air down the line. Our air compressor oils exhibit low volatility and carryover rates, protecting downstream filtration systems from premature saturation.
Under severe ambient heat, standard compressor oils degrade rapidly. Our synthetic formulations resist high thermal stress and protect internal components from wear caused by fine particulate ingestion.
We deliver customized viscosity formulations, specialized chemical additives, and complete label and packaging support.
Reviewing equipment designs, regional climates, and specific target performance parameters.
Developing synthetic or hydrocracked formulations to meet international standards (API/DIN).
Performing oxidation tests, four-ball wear checks, and demulsibility tests in our laboratory.
Utilizing high-precision blending lines to ensure batch-to-batch product consistency.
Safe, compliant packaging with documentation and logistics support for global customs.
Manufactured to ISO specifications and validated by leading international quality registries.
