Champion RotorLub 4000 Semi-Synthetic Rotary Screw Compressor Lubricant – 1 Gallon

Part Number: 28H238

Champion RotorLub 4000 is a premium semi-synthetic rotary screw air compressor lubricant engineered for long service life, exceptional protection, and reliable performance in demanding industrial environments. Formulated with a severely hydrotreated base stock and an advanced additive package, RotorLub 4000 is designed to extend oil change intervals up to 4,000 hours under normal operating conditions, helping reduce maintenance downtime and operating costs.

This high-performance lubricant delivers excellent thermal and oxidative stability across a wide temperature range, resisting breakdown even in high-heat applications. Its superior resistance to varnish and carbon deposits keeps internal compressor components cleaner, improving efficiency and prolonging equipment life. Exceptional demulsibility allows water to separate easily from the oil, protecting the system from corrosion and contamination.

RotorLub 4000 also minimizes oil carryover, reducing makeup oil consumption and overall lubricant costs. It is fully compatible with common compressed air system components and is backed by Champion’s free oil analysis program, providing added confidence in long-term performance and maintenance planning.
