Managing crankcase pressure is an important part of keeping an engine running smoothly. A properly maintained crankcase ventilation filter helps separate oil mist from blow-by gases before they are released back into the intake or atmosphere. This process supports cleaner airflow, reduces oil carryover, and helps protect engine components over time.
At Western Filters, we stock a dedicated range of Donaldson crankcase ventilation filters designed for passenger vehicles, trucks, and heavy-duty applications. These systems are commonly used alongside oil catch cans to control vapour and maintain consistent engine performance. If you are servicing an existing setup or replacing a worn unit, choosing the right filter makes a noticeable difference.
PCV Breathers & Catch Can Filtration You Can Trust
PCV breathers, also known as positive crankcase ventilation breathers, play a key role in regulating internal engine pressure. Over time, these filters can become restricted, which may lead to increased oil consumption or unwanted residue buildup. Regular replacement of a catch can filter, or crankcase breather filter, helps keep airflow balanced and systems working as intended.
Donaldson ventilation filters are built to handle demanding conditions, making them suitable for both on-road and off-road use. Whether you are running a standalone breather system or a full catch can setup, these filters are designed to manage oil mist efficiently without restricting flow. They are commonly chosen for commercial vehicles where reliability and service intervals matter.
