Getting the Longest Life From Your Air Filters
Equipment filters working in low dust conditions last longer. Since it is not possible to
visually determine when a filter reaches capacity, changing air filters too soon can
result in unnecessary labor and filter costs. Conversely, in highly contaminated air, you
may need to change filters earlier than scheduled to ensure full airflow and engine
power. You’ll know exactly when to change your air filters when you use the Cat Air
Filter Service Indicator.
