Lubricant Filling Line Filtration
The last filtration step before packaging — terminal guard filtration between blending/storage and the filling machine.
Final Filtration Before Packaging
The last filtration step before lubricant packaging is critical for removing harmful abrasive particles while maintaining formulation integrity.
Whatever enters the oil after blending — pipeline residue, tank particles, environmental dust — exits through the filling head into the customer's package. Hard particles ≥ 10 µm damage precision filling valves, cause dripping and metering inaccuracy, and end up in delivered product where they can fail OEM cleanliness audits. Terminal guard filtration is the plant's last controlled removal point.

What a Filling-Line Filter Must Deliver
Fill-Rate Flow
JY-DX40-L rated flow 20 m³/h aligned with standard filling-grade flow rates for 32–320 cSt media.
No Line Stops
Three-valve parallel bypass keeps the filling line running during backwash and maintenance — ~30 second manual switchover.
No Media Swap
Gas-pulse regeneration at 0.4–0.6 MPa air supply — zero disposable cartridges to inventory or dispose.
Auditable Performance
β10 ≥ 200 (ISO 16889) provides quantifiable retention reporting for OEM supplier audits.
Managing Bypass Intervals
During bypass operation (V3 open), oil skips precision filtration and the β10 ≥ 200 guarantee cannot be provided for that interval. Recommended practice: schedule the 5–15 minute backwash during batch intervals (drum/tank changes); if mid-production backwash is unavoidable, mark and segregate the affected filled product until third-party particle-count testing releases it; for the strictest lines, configure two JY-DX40-L units in redundant duty.
