02250178-717 Sullair Replacement Combination Cooler

A combination cooler that can no longer shed heat announces itself fast on a Sullair 16 Series or 18 Series machine: climbing discharge temperatures, high-temp shutdowns, oxidized fluid, and extra load on the separator and airend. The American-made 02250178-717 from Stark Industrial Products is engineered to break that cycle and to run with more margin than the cooler it replaces.

The core carries a higher temperature rating and increased fluid capacity for more thermal headroom before a shutdown, and the flow path is designed for lower pressure drop, so the oil pump works less to move fluid through it. Because the unit is 6061 aluminum throughout with no plastic housings, the heat and vibration that crack plastic-housed coolers do not affect it.

One core handles both oil cooling and aftercooling, so replacing a tired 02250178-717 restores two systems at once. We stock it and ship same day on in-stock orders.
