Centrifuge oil 209L part number 290885800

Atlas Copco Centrifugal Oil Part Number 290885800 (209L Large Capacity Specification) is a genuine original lubricant specifically designed for the GA series screw air compressors. It precisely meets the lubrication requirements of core moving parts such as the main rotor and bearings in GA models. As a key component of the lubrication system for GA models, this centrifugal oil primarily serves three core functions: First, it forms a uniform oil film on the meshing surfaces of the main rotor and the rolling elements of bearings, reducing direct friction between metal components, minimizing operational wear, and extending the service life of core parts. Second, through the circulation of the lubricating oil, it efficiently carries away heat generated during the operation of the main unit, working in conjunction with the cooling system to regulate temperature, ensuring that the core components of GA models remain within the optimal operating temperature range and preventing performance degradation or component damage due to overheating. Third, leveraging the oil's inherent cleaning and dispersing properties, it adsorbs and carries impurities such as metal debris from component wear, expelling them through the oil filtration system to maintain the cleanliness of the lubrication system and prevent secondary wear caused by contaminants.
As a genuine original oil product, the production of this centrifugal oil strictly adheres to Atlas Copco's high-standard quality system. It is formulated using high-quality base oils and specialized additives, offering excellent viscosity-temperature characteristics. It maintains stable viscosity across the wide temperature range of GA model operations, ensuring consistent lubrication performance. Additionally, it exhibits outstanding oxidation stability and demulsibility, effectively resisting oxidative degradation and moisture ingress during prolonged operation, thereby extending oil change intervals and reducing maintenance costs. Its oil parameters fully align with the design requirements of the GA model lubrication system, allowing for direct application without the need for additional adjustments or mixing with other oils, avoiding lubrication failures due to oil incompatibility. Through multiple performance tests conducted by the manufacturer before leaving the factory (including viscosity, flash point, anti-wear performance, etc.), this 209L specification centrifugal oil provides continuous and reliable lubrication protection for the GA series air compressors, helping the equipment maintain efficient operation, reduce the frequency of故障停机 (fault停机), and ensure long-term stable operation of the entire machine.
