Advanced engineering solutions designed for optimal heat transfer, wear protection, and systemic efficiency.
In modern industrial manufacturing, screw and reciprocating air compressors serve as the heart of pneumatic automation. Among the elite class of equipment, Quincy compressor systems demand exact technical compliance for fluid dynamics. To achieve minimal mechanical friction, prevent oxidation at elevated temperatures, and reduce oil carryover into downstream systems, sourcing the correct Quincy air compressor oil is paramount.
Global industrial sites face critical choices: matching OEM specifications or integrating equivalent high-performance lubricants that offer superior thermal stability. Shandong Longhai Lubrication Technology Development Co., Ltd., a premier factory supplier and exporter, has engineered precise synthetic formulations. These products serve as high-performance replacements for Quincy OEM fluids like Quin-Syn and Quin-Syn Plus. They ensure global B2B buyers access to highly reliable, cost-efficient fluids that prolong machinery lifecycles.
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a state-level high-tech enterprise integrating R&D, production, and international sales. Over more than 15 years, our team has built a fully integrated supply chain system dedicated to providing high-tier lubrication solutions for the global industrial, automotive, and maritime sectors.
Our company proudly manufactures under our proprietary brand "Century Longhai" alongside our international strategic partnership brand, the British "A Ba" series. Our comprehensive catalog ranges from diesel and gasoline engine oils, gear oils, hydraulic transmission fluids, to highly specialized air compressor lubricants designed for severe working conditions. Our product quality is backed by comprehensive coverage through the People's Insurance Company of China (PICC), ensuring risk mitigation for every international distributor.
Quincy rotary screw air compressors operate under demanding variables: high rotational speeds, continuous duty cycles, and discharge temperatures exceeding 100°C. Standard mineral lubricants quickly degrade, forming carbon deposits and varnish that choke separators and damage internal rotors. Our engineering division addresses these failure modes with a comprehensive formulation roadmap:
We utilize premium Group IV Polyalphaolefin (PAO) and custom Polyol Ester (POE) base oils. This provides a natural viscosity index above 140, ensuring stable film thickness under extreme heat without shearing.
Our oils are blended with advanced primary and secondary antioxidants that arrest the polymerization of hydrocarbons. This maintains a sludge-free crankcase and protects internal parts from lacquer build-up.
Industrial systems encounter massive humidity fluctuations. Our demulsibility additive package enables rapid phase separation, allowing moisture to settle quickly so it can be drained without degrading system performance.
By mimicking the exact physical parameters of Quincy's signature fluid lines—including Quin-Syn, Quin-Syn XP, and Quin-Syn Plus—we deliver compatible products at wholesale pricing. Our synthetic air compressor oils show excellent compatibility with seals and gaskets, ensuring seamless oil changes without system flushing.
International procurement requires stable production cycles and consistent delivery. Shandong Longhai's 131-acre industrial campus is engineered for peak manufacturing agility. By integrating automated blending manifolds and fully automatic filling machinery, we guarantee consistent quality across every batch.
Our filling production lines adopt advanced volumetric and metering principles, keeping filling accuracy margins within 1‰ to 2‰. This automation setup boosts production speeds by 20% to 35%, ensuring quick lead times for high-volume wholesale orders. Our strategic location in Zibo, Shandong, provides access to major petrochemical hubs and direct rail/sea lanes via Qingdao Port, ensuring dependable international shipping.
Our compressor fluids are engineered for demanding scenarios globally. Here is how our premium formulations perform in diverse industrial applications:
Operating Quincy screw compressors for paint booths requires absolutely silicone-free, low-carryover air. Our PAO synthetic line keeps oil carryover rates below 2 ppm, preventing paint defects and reducing filter consumption.
In high ambient dust and extreme heat (+45°C), typical lubricants break down quickly. Our custom-blend Quincy-compatible oils maintain a robust protective film, preventing metal-to-metal contact on rotor lobes.
In sub-zero processing environments (e.g., cold storage or northern climates), our oils offer low pour points down to -45°C. This prevents motor overload during start-ups and guarantees instant system lubrication.
Tailor-made viscosity grades, packaging configurations, and international performance classifications.
At Shandong Longhai, we recognize that different markets require specific product standards. Our OEM/ODM department offers a streamlined path to launch custom products under your own brand:
Our operations comply with international quality, environmental, and occupational safety frameworks.








Our facility is certified under ISO 9001:2015 (Quality Management), ISO 14001 (Environmental Management), and OHSAS 18001 (Occupational Health & Safety). In addition, our automatic transmission fluids carry official Mercedes-Benz approvals, demonstrating our capability to meet stringent global specifications.

Answering key technical questions from procurement officers, engineering managers, and B2B distributors.
Yes. Our synthetic air compressor oils are specifically formulated to match the chemical and physical characteristics of Quincy OEM fluids, such as Quin-Syn and Quin-Syn Plus. They are compatible with the same elastomer seals, gaskets, hoses, and rotor metallurgy. You can transition to our fluids without a complete system flush, provided the previous oil was not heavily oxidized or contaminated.
We formulate our oils using high-quality synthetic bases combined with advanced antioxidant packages. This combination prevents thermal breakdown and oxidation at temperatures above 100°C. In laboratory tests, our oils maintain viscosity stability and resist varnish formation, keeping separators clean and maximizing equipment uptime.
Under standard operating conditions (discharge temperatures below 85°C and clean intake air), our synthetic PAO fluids can achieve service intervals of 8,000 hours, equivalent to OEM standards. We recommend periodic fluid analysis to monitor physical and chemical parameters, especially in heavy-duty or high-temperature environments.
Our blending facility is fully automated, utilizing advanced batch control systems. Every stage, from base oil injection to additive blending, is precisely monitored. Before filling, each batch undergoes strict laboratory testing to verify viscosity, flash point, pour point, water separation, and anti-wear properties against ASTM standards.
We export to clients worldwide, managing all logistics steps from our factory in Zibo to international ports. We handle customs declarations, hazardous material classification (where applicable), and export documentation. This ensures efficient customs clearance and timely delivery to your warehouse.
