Introducing the Donaldson safety air filter, a dependable component for your air intake system. With a length of 14.02 inches, inside diameter of 7.05 inches, and outside diameter of 8.64 inches, this filter is designed to serve as a backup in case of primary filter damage or improper installation. It prevents contaminants from entering the clean side during primary filter servicing. Additionally, it is engineered to plug rapidly if any contamination bypasses the primary filter, alerting operators about the issue. It is recommended to replace safety filters with every third primary filter change, unless there is a primary filter failure.
