Frequently Asked Questions (FAQ)
Q1: What is the main function of the AF25374 filter element?
A: It filters incoming and recirculated air inside the operator cabin of Komatsu heavy machinery, removing fine dust and environmental contaminants to guarantee safe breathing air.
Q2: Which cross-reference numbers match this cabin filter?
A: This unit directly replaces Donaldson P533559 and HiFi Filter SC 17022.
Q3: What are the outer physical dimensions of the AF25374 element?
A: It measures 252.00 mm (9.92 in) in length, 153.80 mm (6.06 in) in width, and 56.00 mm (2.20 in) in height.
Critical Maintenance Considerations
- Regular Inspection & Replacement: Inspect the cabin filter every 250 operating hours in high-dust mining zones. Replace immediately if cabin airflow drops or noticeable dust accumulation occurs.
- Avoid High-Pressure Washing: Do not wash this element with pressurized water or harsh chemical detergents, as moisture breaks down the media structure and compromises particle retention.
