Compressors are the core power equipment in industrial production. Screw, piston, and oil-free turbo/centrifugal models operate under prolonged high-temperature, high-pressure, and continuous running conditions. The quality of the lubricant directly determines the operational stability of the main unit and the total lifecycle maintenance cost. Conventional oils are highly susceptible to oxidation under long-term high-temperature cycling, generating sludge and carbon deposits that clog oil passages and oil-gas separators. At the same time, short oil drain intervals and frequent shutdowns for servicing seriously constrain productivity. Piston compressors can reach final compression temperatures as high as 220°C, placing extremely stringent demands on oil aging resistance and high-temperature detergency. Oil-free compressors, on the other hand, must balance gear and bearing lubrication with air purity, preventing oil mist volatilization from contaminating process streams. Different compressor types have completely different lubrication requirements, and a single general-purpose oil cannot adequately serve all scenarios.

FUCHS compressor lubricants fully cover oil-injected screw, piston, and oil-free models, with a tiered portfolio ranging from mineral, semi-synthetic, to fully synthetic products to match diverse operating conditions. Our solutions deliver balanced optimization across thermal oxidation stability, carbon resistance, extended oil drain intervals, and system cleanliness protection, effectively reducing main unit wear and unplanned downtime, and helping compressed air systems operate reliably and efficiently throughout their entire service life.
