This Must Be What You Care About Most
Three-Stage Filtration Concept
Compatible Replacement — Three Stages
The Triple R filter insert replacement combines a special cellulose medium with an optimized multi-layer structure, creating a 114mm thick filter buildup through axial flow design.
- Stage 1: Big particles stay on top of the element
- Stage 2: Smaller particles captured in upper non-compressed part
- Stage 3: Smallest particles captured in lower compressed part
Unique 3-in-1 technology: Simultaneously removes solid particles, water, sludge, varnish and oxidation residues.
Process & Structure Improvements
Skeleton Strength Improvement
Innovation
Enhanced skeleton design ensures structural integrity under high differential pressure and extreme operating conditions across all filter series.
| Series | Existing Issue | Customizable Process Improvement | Optimization Result |
|---|---|---|---|
| WE-100 | Media mechanical strength degradation and flow channel collapse after water saturation | Embedded improved support skeleton | Prevents center channel closure under high differential pressure, maintains structural integrity |
| D-series | Inter-stage stress compression and inhomogeneous deformation at flexible cross-sections | Upgraded inter-stage separator plate | Rigidly distributes axial hydraulic load, eliminates inter-chamber bypass and stage misalignment |
| WG-series | Coated skeleton triggering fluid electrochemical corrosion and adhesive hydrolysis | Anodized aluminum / 316 stainless steel skeleton + anti-hydrolysis curing resin | Blocks chemical erosion from extreme reactive media, ensures high chemical stability |
| WS-series | Bending yield strain and coalescence failure under high-flow high-viscosity conditions | Modified polyester fiber composite skeleton | Enhances bending stiffness under ultra-high flow rates, ensures efficient coalescent retention |
Structural Constraint Improvement
Innovation
Advanced constraint structure design locks filter media boundaries precisely, preventing media migration and ensuring stable filtration performance under high-shear conditions.
| Series | Existing Issue | Customizable Process Improvement | Optimization Result |
|---|---|---|---|
| WE-100 | Volume swelling deformation caused by radial stress release after water saturation | Optional high-tension rigid constraint outer mesh | Locks maximum outer diameter tolerance, enables smooth flexible removal and replacement |
| E / X | Paper envelope layer swelling emulsification and fiber migration under heavy loads | Optional reinforced outer mesh | Locks physical outer boundary, completely eliminates media fiber shedding under high-shear oil flow |
| V-series | Microscopic escape of adsorbed fine powder under hydraulic high-frequency pulsed loading | Optional triple-layer high-density constrained encapsulation | Blocks molecular-level powder mechanical penetration and leakage under pulsed pressure |

SINFT Depth Filtration — Why Natural Cellulose?
Only natural cellulose delivers both hydrophilicity and surface activity
Only natural cellulose possesses extremely strong hydrophilicity (water absorption) and surface activity (sludge adsorption) — this is another application of SINFT depth filtration technology.
The Secret of Durability: SINFT does not use short fibers from conventional filter paper. Instead, it uses extremely strong, specially chemically treated high-purity long needle-leaf wood fibers. After these fibers interweave, the tensile strength and oil-water soaking resistance are extremely high — the structure will not disintegrate even after years of use in lubricating oil.
How SINFT Ensures Triple R Filter Performance
Advanced Testing Equipment
Oil quality demands extremely high requirements for filter stability and compatibility. SINFT has established a complete filter testing process with professional equipment to ensure reliable performance under demanding conditions.
- Compatibility testing rigs
- Bubble test benches
- Burst strength monitors
- Air permeability testers
- Differential pressure detection equipment
From filter media pore size, structural strength to fluid performance — all indicators are strictly tested to ensure stable filtration performance and low pressure drop under high pressure and high flow conditions.
Clean Production Environment
ISO Class 8 Cleanroom
High-precision hydraulic systems have extremely high requirements for initial cleanliness of filter elements. SINFT uses ISO Class 8 cleanrooms for high-precision hydraulic filter production and assembly — effectively reducing fiber shedding, dust and metal particle contamination risks.
- ISO Class 8 certified environment
- Low fiber shedding design
- Reduced particulate contamination
Clean production environment helps hydraulic systems reduce pollutant circulation and improve equipment operation stability and filter service life.
Three-Stage Quality Control System
From incoming materials to final shipment — every step is strictly controlled
| Stage | Content | Mechanism |
|---|---|---|
| Incoming Inspection | Raw material / filter media incoming testing | Warehouse software auto-tracking, low-level auto-alert |
| In-Process | Production process key control points | Certified operators + core technicians quality gate |
| Pre-Shipment | Every batch strictly inspected before shipment | Guarantee every product meets performance standards |
