The basic information for the PAAF629330 fuel filter element (interchangeable part number WAR88679) is as follows:

1. Filtration Accuracy

Standard paper filter media: 10 µm; optional glass fiber: 1–70 µm, metal mesh: 3–400 µm, filter paper: 5–40 µm, measured according to ISO 16889 multiple pass method (β≥1000).

2. Operating Pressure and Temperature

- Rated pressure: 0.6–6 MPa (6–60 bar, custom sizes up to 16 bar or 420 bar available)

- Operating temperature: 0–80 ℃ (general purpose), custom high-temperature models up to 120 ℃.

3. Flow Rate Range

Rated flow rate: 100 L/min (common value), series coverage: 2–2600 L/min, initial differential pressure ≤0.2 MPa, recommended differential pressure is 1 bar, maximum allowable 3.5 bar.

4. Filter Media and Structure

Pleated cylindrical filter element, outer shell made of iron or plastic; filter media options include paper, fiberglass, stainless steel mesh, sintered felt/powder; spin-on type, with bypass valve and blockage indicator (optional).

5. Testing Standards
