About Water Mist Catcher (water separator)

Situated after the charge air cooler, the water mist catcher (WMC) separates water droplets from the cooled air. The droplets naturally condense from humid hot air during the cooling process. It is advantageous to remove this moisture before it enters the engine.

For larger 2 stroke engines the water mist catcher is a separate unit placed in the cooler housing.

For 4 stroke engines some charge air coolers has an integrated water mist catcher.
