Simplex Oil Strainer acc. to JIS F7209

Simplex Marine Oil Filter JIS F7209

Simplex oil strainer for marine piping systems, designed in accordance with JIS F 7209-1996 and tested per JIS F 7200-1996. The specification includes a hydrostatic body test at 0.74 MPa. Typical use is in shipbuilding for simplex oil strainers.

Construction Materials

As per referenced table:

• Body: FC200
• Bonnet: FC200
• Cover push: FCD400
• Filter element: SS400 / SUS304 (as specified)
• Sealing: O-ring

Filter element selection should consider oil viscosity, operating temperature, permissible pressure drop, and downstream equipment protection requirements.

Typical Applications

Used in lube oil lines and auxiliary engine room circuits, upstream of pumps, regulators, oil coolers, or equipment sensitive to metallic particles, deposits, or maintenance residues.

Selection Criteria

• Standard: JIS F7209
• Type: simplex oil strainer
• Pressure classes: 5K and 10K by DN
• Typical sizes: DN20 to DN40
• Body test pressure: 0.74 MPa
• Confirm: DN, flange drilling, mesh, O-ring material, temperature, oil type

Maintenance

Simplex filters require line isolation for cleaning. Periodic inspection should include differential pressure, basket cleanliness, O-ring condition, cover tightness, flange wear, and possible filter element deformation.

FAQ

Is this a duplex filter?
No. As a simplex type, cleaning requires operational isolation.

Is it suitable for water?
This specification is for oil filtration.

What must be confirmed before procurement?
Class 5K or 10K, DN, JIS flanges, mesh, sealing material, and oil service conditions.
