Crankcases produce oil and mist particulate emissions in marine and stationary reciprocating engines and gen-sets. These emissions can compromise your engine’s performance and lead to expensive repairs in the future. The solution? Crankcase ventilation systems capture these hazardous blow-by emissions. A high-efficiency CCV filter prevents oil mist from discharging into the atmosphere in an open configuration. Additionally, a crankcase filter protects an engine’s turbocharger, intercooler, and exhaust catalyst from contamination in a closed configuration. Solberg’s crankcase filtration solutions optimize engine performance and reduce the number of costly operator repairs. Both open and closed style ventilation systems regulate crankcase vacuum/pressure via manual or automatic controls, preventing leaks and oil loss through the engine seals.
