Today‘s diesel engines need to maintain high performance levels to remain compliant with stringent Tier 4 emissions regulations. Fuel filtration plays a key role, with current high pressure common rail fuel injectors operating at pressures up to 2,000 - 3,100 bar / 30,000 - 45,000 psi. This means it's important to deliver CLEAN FUEL to today‘s precision designed fuel system pumps and injectors to maintain performance. Today's engines also operate in a wide range of environments that include vibration, fuel pump pulsation and surging fuel flows. It all adds up to big challenges for your fuel filters.
That's exactly why we developed Donaldson Blue® filters with our pioneering media technology, Synteq XP. Donaldson Blue® DBF5782 consistently retains particles under high pressure common rail fuel system dynamics (engine vibration), protecting your hard-working equipment and maximizing your uptime. Compared to the competition’s best product, the Donaldson Blue® DBF5782 averages 4x CLEANER under heavy-duty vibration testing over the life of the filter. Lower particle release means less micro-contamination is flowing downstream to the fuel injectors.
Donaldson Blue® filters deliver the cleanest fuel – period.
1. Unscrew and remove the old filter and gasket.
Properly dispose of the used filter according to local regulations.
2. Wipe the filter head with a clean cloth.
3. DO NOT pre-fill with fuel.
4. Apply a thin film of clean motor oil to the gasket.
5. Align threads; spin filter on until gasket contact.
6. Follow icons on filter to tighten to tighten the appropriate amount.
7. Start engine and check for leaks.
Donaldson provides best practices and recommended steps for fuel filter servicing. Effective fuel filter maintenance is the key to optimal engine performance.
