Introducing the Donaldson safety air filter, meticulously designed to meet ISO 5011 standards without making extravagant claims. This filter serves as a crucial backup in case of primary filter damage or incorrect installation, ensuring uninterrupted operation. It acts as a barrier, preventing contaminants from infiltrating the clean side of the air intake system during primary filter servicing, maintaining system integrity. In the event of contamination bypassing the primary filter, our design ensures rapid plugging, promptly alerting operators to address the issue. With a length of 27.76 inches, an inside diameter of 8.07 inches, and an outside diameter of 9.88 inches, this filter exemplifies reliability and efficiency.
