88290001-357 / 88290020-661 SULLAIR Oil Cooler

Oil coolers used in Sullair air compressor systems regulate lubricant temperature to maintain viscosity and protect internal components. Assemblies such as 88290001-357 and 88290020-661 support stable oil cooling under continuous operation. Over extended service, fouling and thermal degradation may increase oil temperature. From a replacement and service perspective, oil cooler replacement restores original cooling performance and supports long-term compressor reliability.
