100% Viscose (Rayon) Nonwoven Filter Media | For Oil & Lubricant Filtration
The Chenyang Advantage for Filtration
- The Chenyang Advantage for Filtration:
- Superior Dirt-Holding Capacity (DHC): Natural cellulose structure traps more contaminants, extending filter life.
- Excellent Compatibility: Ideal for synthetic, mineral, and biodegradable oils. Low risk of chemical interaction.
- Controlled Porosity & Graded Density: Engineered for balanced efficiency and flow rate.
- Inherent Hydrophilicity: Naturally absorbs water, beneficial for certain lubricant conditioning applications.
Engineered Cellulose Media for Demanding Filtration Tasks
Chenyang's 100% Viscose (Rayon) Nonwoven is a premium filter media manufactured from pure wood pulp cellulose. Its natural, randomly oriented fiber matrix creates a deep-bed filtration effect with a high surface area, making it exceptional for capturing fine particulate, sludge, and oxidation products in circulating oil and coolant systems.
Key Technical & Operational Benefits:
- High Dirt-Holding Capacity: The three-dimensional web holds significantly more contaminant than many synthetic media before reaching pressure drop limits, reducing change-out frequency and operational cost.
- Fine Filtration Efficiency: Can be engineered to achieve target micron ratings, providing protection for sensitive hydraulic components and bearings.
- Material Safety: Free from chemical binders (true spunlace process), reducing the risk of media migration or additive depletion in the oil.
- Thermal Stability: Suitable for typical operating temperatures in lubrication and hydraulic systems.

FAQ
Q: How does viscose compare to meltblown polypropylene for oil filtration?
A: Viscose offers higher DHC and natural hydrophilicity. PP may offer finer initial ratings and better chemical resistance to strong acids/alkalis. The choice depends on the specific oil and contaminant profile.
Q: Can this media be pleated?
A: Yes, our media can be engineered with the appropriate stiffness and tensile strength for successful pleating. We recommend testing our sample swatches on your equipment.
Q: What is the lead time for a custom-developed media?
A: Development and sampling can take 4-8 weeks. Production lead times depend on order volume and are highly competitive due to our integrated facility.
