DFO-614PLF25 diesel particulate filter element

 I. Model Analysis (DFO Naming Convention)

- `DFO`: Diesel Fuel Oil

- `6`: Outer Diameter 6" (152.4 mm)

- `14`: Length 14" (355.6 mm)

- `PLF`: Pleated Filter Media

- `25`: Filtration Accuracy 25 μm

 II. Technical Parameters

- Filtration Accuracy: 25 μm (nominal), highly effective at intercepting dust, rust, and colloidal particles

- Filter Media Structure: Deeply Pleated Glass Fiber/Composite Fiber, high dirt holding capacity, long service life

- Dimensions (Outer Diameter × Inner Diameter × Length): φ152.4 × φ88.9 × 355.6 mm (6" × 3.5" × 14")

- End Cap: Double Opening (DOE); Optional threaded base (TB) for easy installation

- Sealing Material: NBR (Nitrile Butadiene Rubber), resistant to diesel/biodiesel

Maximum Operating Temperature: 107℃ (225°F)

Pressure Resistance/Collapse Pressure: 75 psi (5.2 bar)

Replacement Pressure Differential: 25 psi (1.7 bar)

Applicable Media: Diesel, Biodiesel (B100), Kerosene, Light Fuel Oil

pH Range: 5–9 (continuous operation)

 III. Core Functions

Solid Particle Removal: Removes dust, rust, sand, and metal shavings of 25 μm and above from diesel fuel, protecting the high-pressure fuel pump, injectors, and common rail system.

High Fouling Capacity Design: Deeply pleated structure with high fouling capacity; lifespan up to 3000–5000 hours (depending on contamination level).

Strong Compatibility: Compatible with pure diesel and biodiesel blends, compliant with ISO standards. 4406 Cleanliness Standard
