- Emissions & Pressure Control : Relieves crankcase pressure build-up to prevent oil seal leaks while capturing hazardous oil mist to comply with environmental emissions standards.
- Engine Protection : Prevents sludgy oil deposits from coating downstream air intake systems, turbochargers, and intercoolers.
- Compatibility : Commonly used across heavy-duty Cummins engines (such as N14, NT855, and KTA series variants depending on housing setup) in commercial trucking, marine, generator, and industrial equipment applications.
- Maintenance : Typically replaced during scheduled major oil or filter service intervals to ensure unrestricted crankcase venting.
The 255180 Cummins crankcase ventilation filter (or breather assembly) is a filtration component designed for heavy-duty Cummins diesel engines. It removes oil mist, aerosol droplets, and airborne contaminants from blow-by gases escaping the engine crankcase before those gases are vented or recirculated.
