FAQ
Q1: Is the AF25549 a primary filter or a safety (inner) filter?
A: The AF25549 is a Primary Air Filter (Outer Filter). In most dual-stage air intake systems, it is designed to be used in conjunction with a safety filter for maximum engine protection.
Q2: How often should I replace the AF25549?
A: The replacement interval depends on the severity of your operating environment. Always follow the maintenance schedule provided by your equipment manufacturer. For dusty environments (e.g., mining, construction), more frequent inspections are recommended.
Q3: Do I need to replace the safety filter (AF25550) when I change the primary filter?
A: Yes, it is highly recommended. By the time the primary filter is due for replacement, the safety filter may have captured fine particles that passed through. Retaining a clogged safety filter can allow contaminants to migrate into the engine.
