The basic information for marine hydraulic oil filter element 1940385 is as follows (based on supplier data from August 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 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: 2–2600 L/min (at a viscosity of 30 cSt); initial differential pressure ≤0.2 MPa, recommended to replace with a differential pressure of 1 bar, maximum allowable 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 cycles), ISO 3968 (differential pressure-flow), ISO 4572/16889 (multiple pass filtration performance).

6. Typical Marine Applications

Marine steering gear, anchor winches, hatch covers, cranes, and side thruster hydraulic stations; also suitable for high-pressure hydraulic systems in heavy industries such as power plants, steel mills, tunnel boring machines, and petrochemical plants.
