| High Light | 25 micron nylon filter bag ，monofilament mesh oil filter ，liquid filter bag with warranty | ||
The 25 Micron Nylon Monofilament Mesh Filter Bag is precision-engineered for fine oil filtration and industrial liquid-solid separation applications. Constructed from high-grade nylon monofilament mesh with a consistent 25-micron square-hole weave, this filter bag delivers superior particle retention and excellent flow-through performance for hydraulic oil, lubricating oil, cutting fluid, and chemical solvent filtration.
Unlike non-woven felt bags that trap particles randomly, the uniform square mesh structure ensures predictable and repeatable filtration results, making it ideal for applications requiring precise micron-rated separation with minimal pressure drop. FDA certified for food-grade compatibility and available in a full range of sizes with OEM customization support.
| Pain Point | Impact on Your Operation |
|---|---|
| Inconsistent Micron Accuracy | Low-quality mesh with uneven hole size causes unpredictable filtration, allowing oversized particles to bypass and contaminate downstream processes. |
| Mesh Clogging and Flow Restriction | Poor surface finishing causes particle adhesion, leading to rapid clogging and reduced flow rates that force frequent cleaning or replacement. |
| Seam Leakage at High Pressure | Weak seam construction fails under pressure differential, allowing unfiltered liquid to bypass the mesh and contaminate the filtered output. |
| Advantage | Details |
|---|---|
| Uniform 25 Micron Square Weave | Precision-woven nylon monofilament ensures consistent square hole openings at exactly 25 micron, delivering repeatable and predictable filtration performance batch after batch. |
| Monofilament Construction | Single-strand nylon fibers eliminate fiber shedding common with multifilament mesh, ensuring zero secondary contamination in sensitive oil and chemical applications. |
| Ultrasonic Welded Seams | Each bag features ultrasonically welded edges that prevent seam blowout under pressure, ensuring zero bypass and maximum filtration integrity throughout its service life. |
| FDA Food Grade Certification | Constructed from FDA-compliant food-grade nylon mesh, suitable for edible oil filtration, beverage processing, and other food-contact applications. |
| Wide Chemical Compatibility | Nylon monofilament offers excellent resistance to solvents, oils, alkalis, and most organic chemicals, with an operating temperature range up to 149 Celsius (300 Fahrenheit). |

Q: Why choose nylon monofilament over multifilament mesh?
A: Monofilament mesh uses single-strand fibers that do not shed, eliminating secondary contamination. It also provides more precise and consistent micron ratings compared to multifilament alternatives.
Q: Can you customize the bag dimensions and micron rating?
A: Yes, we support full OEM customization. Non-standard dimensions, specific micron ratings from 0.5 to 300 micron, and custom collar types are all available upon request.
Q: Is this filter bag suitable for edible oil filtration?
A: Yes, our nylon monofilament mesh is FDA food-grade certified and BPA-free, making it safe for edible oil, beverage, and food processing applications.
Q: What is the minimum order quantity and delivery time?
A: MOQ is 10 pieces for standard sizes. Delivery takes 5-10 working days for stock items and 15-20 days for custom production orders. Free samples are available for evaluation.
