Donaldson P550049 Spin-on Fuel Water Separator Filter

Description

Application Scope:

1. Primary Fit: Mitsubishi Fuso/Fighter/Super Great trucks (2000-present), Mitsubishi industrial engines (6D16, 6D22, 4M50), and equipment requiring ME016823 filter.

2. Cross-Model Compatibility: Bobcat (6599194), Caterpillar, Case IH (FC405), Atlas, Airman-Hokuetsu, John Deere, and other commercial vehicles with cross-reference parts.

3. Ideal Use Cases: Construction machinery, agricultural equipment, generators, cold chain logistics, and off-road vehicles in high-dust/humidity regions.

Filtration Technology & Benefits:

1. Hydrophobic Media & Water Separation

The specialized hydrophobic cellulose blend repels water while trapping particles, preventing injector corrosion and abrasive damage. Critical for Mitsubishi’s high-pressure fuel systems to maintain fuel atomization and reduce fuel consumption.

2. Spin-on Design for Fast Maintenance

Tool-free installation and replacement minimize vehicle downtime. The integrated water collection chamber with a drain valve allows quick water removal without filter disassembly—essential for humid/rainy regions.

3. Durable Construction

Reinforced steel housing withstands vibration, extreme temperatures, and pressure fluctuations in heavy-duty use, extending service life and reducing total cost of ownership.
