Cat secondary engine air filters are your last line of defense against dust, dirt and other contaminants that may damage the components of your income-producing machinery. Tasked with protecting the engine while the primary filter is being changed or in the event of a breach in the main filter, this secondary unit plays a critical role in preventing damage due to contaminants.
• Increased airflow with less restriction
• Serves the critical role of back-up filtration
