Introducing the Donaldson safety air filter, an essential component designed to ensure the smooth operation of your air intake system. Serving as a dependable backup, it steps in seamlessly in case of primary filter damage or improper installation, providing uninterrupted filtration. This filter acts as a vigilant shield, preventing contaminants from infiltrating the clean side during primary filter servicing, thereby prolonging the life of your system. In the event of contamination breaching the primary filter, the rapid plugging mechanism promptly alerts operators, enabling swift intervention. For optimal maintenance, 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 14 inches, an inside diameter of 4.85 inches, and an outside diameter of 5.95 inches, it stands as a reliable guardian for your air intake system.
