Description
The DEC-R-46 Rotary (Screw) Air Compressor Oil is a premium synthetic-blend lubricant engineered for high-performance operation in rotary screw air compressors. This advanced fluid delivers superior wear protection, thermal stability, and oxidation resistance, ensuring reliable performance, low oil carryover, and extended service life in continuous-duty screw applications.
Formulated with highly refined base oils and a specialized anti-wear additive system, DEC-R-46 minimizes varnish and sludge buildup, maintains viscosity under high temperatures, and provides excellent air/oil separation. Its exceptional demulsibility and anti-foam properties prevent water contamination and maintain clean system operation even in humid environments.
Designed for extended drain intervals and broad OEM compatibility, DEC-R-46 meets or exceeds requirements for most rotary screw compressors. Ideal for manufacturing, automotive, and industrial processing, it ensures smooth rotor operation, reduces energy consumption, and supports maximum compressed air system efficiency.
