Description
The DEC-RSB-46 Rotary (Screw) Air Compressor Oil (Synthetic Blend) is a premium synthetic-blend lubricant engineered for superior performance in modern rotary screw air compressors. This advanced fluid combines the thermal stability of synthetic base stocks with the cost-effectiveness of refined mineral oils, delivering exceptional wear protection, extended drain intervals, and reduced oil carryover in high-efficiency, continuous-duty applications.
Formulated with a balanced blend of PAO/ester synthetics and high-VI mineral oils plus a robust anti-wear additive package, DEC-RSB-46 resists thermal breakdown, prevents varnish and carbon deposits, and maintains viscosity stability across wide temperature ranges. Its superior air-release and anti-foam properties ensure rapid oil separation, minimal foaming, and clean operation even in humid, high-speed environments.
Designed for extended service life and full OEM compatibility, DEC-RSB-46 meets or exceeds the demanding requirements of leading rotary screw compressor manufacturers. Ideal for food processing, electronics, and precision manufacturing, it ensures smooth rotor operation, lowers energy consumption, and supports maximum system uptime with reduced maintenance.
