02250224-359 Sullair Replacement Oil Cooler

The 02250224-359 Sullair Replacement Oil Cooler is an aftermarket-equivalent cooling unit for Sullair portable air compressors. This cooler maintains proper lubricant temperature in the compressor system, preventing thermal degradation that leads to varnishing, reduced lubrication, and accelerated component wear.

Oil coolers on portable compressors fail from corrosion, impact damage, vibration fatigue, and internal fouling over time. Elevated oil temperatures are one of the most common causes of premature airend and bearing failure in rotary screw compressors. A cooler that is leaking, plugged, or thermally underperforming compromises the entire compressor system’s reliability and longevity.

The 02250224-359 is designed to match the original cooler’s dimensions and thermal performance. During installation, clean the mounting area, verify hose and fitting connections, fill to the correct lubricant level, and run a full-load heat test to confirm oil temperatures stabilize within Sullair’s specified operating range.
