Introducing the Donaldson safety air filter, a crucial component ensuring the integrity of your air intake system. Acting as a reliable backup, it steps in seamlessly if the primary filter is damaged or improperly installed, ensuring uninterrupted filtration. This filter serves as a vigilant protector, preventing contaminants from infiltrating the clean side during primary filter servicing, ultimately extending the life of your system. In the event of contamination breaching the primary filter, the rapid plugging feature immediately alerts operators, enabling swift intervention. To maintain peak performance, we recommend replacing safety filters every third primary filter change, except in cases of primary filter failure. Compliant with ISO 5011 standards, the Donaldson safety air filter is engineered to meet industry benchmarks. With a length of 12 inches, an inside diameter of 6.04 inches, and an outside diameter of 7.64 inches, it stands as a reliable guardian for your air intake system.
