The basic information for marine hydraulic oil filter element 82749 is as follows (based on supplier data from September 2025):

1.Filtration Accuracy

Standard supply is 1–70 µm (glass fiber), achievable from 0.01 µm to 500 µm depending on operating conditions; accuracy is determined by the ISO 16889 multiple-pass method (β≥1000).

2.Operating Pressure and Temperature

- Rated operating pressure ≤450 bar (instantaneous peak 420–450 kg·f/cm²)

- Operating temperature -30 ℃～+120 ℃

3.Filter Media and Structure

Standard configuration is a glass fiber pleated filter layer + galvanized perforated mesh skeleton; stainless steel mesh, sintered felt/powder sintered, polypropylene, filter paper, etc. are also available. The outer shell is iron, screw-on type, and can be equipped with a bypass valve and blockage indicator.

4.Flow Characteristics

Rated flow rate: 6–100 L/min (at a viscosity of 30 cSt); initial differential pressure ≤0.2 MPa, recommended to replace with a 1 bar differential pressure, maximum permissible 3.5 bar.

5.Testing Standards

ISO 2941 (bursting resistance), ISO 2942 (structural integrity), ISO 2943 (material compatibility), ISO 3723 (end-load), ISO 3724 (fatigue cycling), ISO 3968 (differential pressure-flow rate), ISO 4572/16889 (multiple-pass filtration performance).
