JY-DX40-L — Production-Line Precision Filtration for Lubricant Manufacturers
Skid-mounted terminal guard filtration installed between blending/storage and the filling line. Regenerable polymer rigid composite membrane, three-valve non-stop bypass design.
JY-DX40-L — Equipment Views
The JY-DX40-L is a skid-mounted production-line lubricant filtration system manufactured by Jingyuan (Shenyang Jingyuan Membrane Systems Co., Ltd.). It is installed between the blending kettle/storage tank and the filling line of lubricant plants (LOBP). Rated flow is 20 m³/h for 32–320 cSt lubricants, with selectable 5 µm or 10 µm precision and β10 ≥ 200 absolute retention (ISO 16889). The membrane is regenerated by gas-pulse backwash — no disposable filter cartridges are used. A three-valve parallel bypass allows filling-line production to continue during backwashing and maintenance. JY-DX40-L systems are deployed on production lines at a U.S. lubricant manufacturer.
Blending → Filtration → Filling
The JY-DX40-L occupies one specific position in the lubricant plant: the last precision filtration step before packaging.
Solving Production Problems, Not Just Filtering Oil
Disposable Cartridge Replacement
Traditional string-wound, melt-blown and pleated cartridges require high-frequency replacement under high viscosity, causing stop maintenance, media inventory and disposal costs. The JY-DX40-L runs consumable-free with gas-pulse membrane regeneration.
Extrusion Bypass & Fiber Shedding
Soft media deform under cold-start pressure surges, letting particles squeeze through; shed fibers contaminate finished oil. The rigid membrane pore geometry is sintered into the polymer matrix — stable pores, physically no free fibers.
Production Interruption
The three-valve parallel bypass (V1/V2/V3) allows backwashing and maintenance without stopping the filling line. Switching to bypass takes approximately 30 seconds, manually operated.
Particle Contamination
Hard abrasive particles ≥ 5–10 µm from pipelines, tanks and the environment are intercepted with β10 ≥ 200 absolute retention — 99.5% of particles ≥ 10 µm removed, ISO 16889 multi-pass tested.
Final-Product Quality Control
Quantifiable β10 ≥ 200 reporting supports OEM audits and outgoing-batch cleanliness commitments, replacing unverified "nominal rating" claims.
Formula Protection
The 5–10 µm pore window is engineered to balance contaminant removal and formulation compatibility — filtration precision is selected, not simply minimized. Membrane surfaces are chemically inert with no polar static charge.

JY-DX40-L — Common Questions
Will the 5–10 µm precision affect detergent-dispersants or viscosity index improvers?
Detergent-dispersant micelles are typically 0.01–1 µm and long-chain VII hydrodynamic diameter is roughly 2–5 µm — both smaller than the minimum 5 µm pore size, so the design target is to avoid removing them. The membrane surface is chemically inert with no polar static charge, which is intended to minimise electrostatic adsorption of these polar molecules. Media with pores that are too small (1–3 µm) are what intercept VIIs and alter formulas. Actual additive retention is confirmed per formulation — for application-specific confirmation of your oil, contact Jingyuan engineering.
What is the difference between β10 ≥ 200 and a "nominal 10 µm" rating?
A nominal rating is an unverified manufacturer claim. β10 ≥ 200 is based on the ISO 16889 multi-pass test: for every 200 particles ≥ 10 µm upstream, only 1 remains downstream — 99.5% absolute retention. This provides quantifiable reporting for OEM audits.
How is the membrane regenerated?
By gas-pulse backwashing using 0.4–0.6 MPa compressed air / N₂, triggered at 0.5 MPa differential pressure. No disposable cartridges, no media swap-out.
Do membrane modules need replacement?
The membrane modules have a design lifespan ≥ 3 years under standard operating conditions (temperature ≤ 80°C, regular gas-pulse regeneration). When replacement is eventually required, membrane modules can be replaced independently without scrapping the skid.
