Crankcase Replacement Filters


crankcaseDuring the combustion process of reciprocating engines, crankcase emissions are created. Such emissions include, unburned fuel and blow-by gases, as well as hydrocarbon vapor, diesel soot (PM) and other various engine oil contaminants.

Open crackcase vents will be present in medium- and heavy-duty turbocharged diesel engines. This is because closing them could allow blow-by contaminants to foul the turbocharger and aftercooler components if left unfiltered. Donaldson’s SpiracleTM Crankcase Filtration System (CFS) will successfully eliminate harmful and unwanted crankcase emissions. This ensures the crankcase can be closed without degrading performance.
