Explore our elite selection of industrial oils engineered to withstand high temperatures, high pressures, and extreme workloads.
In modern industrial pneumatics, the terminology "Air Compressor Free Oil" or premium synthetic lubricant selection references chemical compounds formulated to reduce carryover, carbon deposition, and downstream pollution. For applications operating at high temperatures, typical standard mineral oils deteriorate, causing varnish that leads to system failures.
Our formulations use advanced synthetic base stocks (PAO/Polyalphaolefin & Ester combinations) designed to resist thermal breakdown. By maintaining molecular consistency under high friction and stress, these fluids ensure high demulsibility, parting rapidly from atmospheric moisture. This maximizes separation efficiency and protects downstream filters, preventing oxidation buildup.
Unrefined lubricants lead to oxidation, causing varnish buildup on rotors and valves. Using PAO-based synthetic lubricants ensures stability, keeping screws clean and reducing energy consumption.
Headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating R&D, production, and sales. Deeply involved in the lubricant industry for over 15 years, the company has built a complete industrial chain system, committed to providing high-quality lubrication solutions for global industrial and transportation fields.

As industries move toward carbon-neutral operations, industrial lubrication must adapt to minimize environmental impact. Shandong Longhai is shifting R&D focus toward biodegradable ester formulations that reduce carbon footprints without sacrificing thermal performance.
Our future products will focus on low-viscosity formulations designed for modern high-speed compressors, reducing frictional power losses by up to 2.4%. We are also developing inline sensor-compatible lubricants to support real-time oil condition monitoring within IoT-driven industrial facilities.
