Replacement Leemin Oil Filter WU-400X100F-J Huahang Filter Supply

Description:

The Replacement Leemin Oil Filter WU-400X100F-J is designed as a direct, form-fit-function replacement for the original Leemin SFX series filter, delivering reliable protection for sensitive hydraulic components in demanding applications.

The SFX series is typically used in high-pressure line applications, where the element must withstand significant pressure surges and flow fluctuations without collapsing or bypassing . The robust construction includes rigid metal end caps and a heavy-duty support cage that maintains structural integrity even under extreme operating conditions .

FAQ

Q1. Is this a direct replacement for the original Leemin filter?

A: Yes. This element is manufactured to be a form, fit, and function replacement for the original Leemin . It matches the exact dimensions, sealing configuration, and performance characteristics, ensuring a drop-in replacement without any modifications .

Q2. What is the collapse pressure rating of this filter?

A: The WU-400X100F-J is designed for high-pressure applications with a collapse pressure rating of up to 210 bar (3045 psi) . This allows the element to be installed in pressure lines where it may be exposed to pressure surges and differential pressure spikes .

Q3. How often should I replace this filter element?

A: Replacement intervals depend on your system's operating conditions and contamination levels. Most systems use a differential pressure indicator to signal when the element is becoming clogged and needs replacement. Under normal conditions, replacement is typically performed during scheduled maintenance based on operating hours or pressure drop readings .

Q4. What is the difference between the SFX series and the TZX2 series from Leemin?

A: The SFX series is typically designed for high-pressure line applications (up to 210 bar) with collapse-resistant construction. The TZX2 series is generally used in return line applications where pressure ratings are lower.
