As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality filtration solutions for the global food industry. Our PE Liquid Filter Bag (5 Micron) is engineered specifically for the demanding filtration of sauces, syrups, and other viscous food liquids. With a proven track record of exports exceeding US$5 million annually to markets across North America, Europe, and Asia, we deliver reliable performance that meets the strictest hygiene and efficiency standards.
This filter bag is constructed from high-grade polyester (PE) felt, offering excellent chemical resistance and mechanical strength. The 5-micron rating ensures precise particle removal, preventing clogging in downstream equipment while maintaining high flow rates. Whether you are filtering thick tomato ketchup, fruit syrups, or soy sauce, our bag provides consistent clarity and extended service life.
Key Features & Technical Specifications
- Material: 100% virgin polyester needle-punched felt – food-grade, non-toxic, and odorless.
- Filtration Efficiency: 5 micron nominal rating with >90% removal efficiency for particles ≥5 μm.
- High Temperature Resistance: Continuous operation up to 90°C (194°F), suitable for hot-fill processes.
- Strong Seam Construction: Double-stitched or heat-sealed seams to prevent bypass and bursting under pressure.
- Compatible with Standard Housings: Fits most #1, #2, #3, and #4 bag filter housings (ring options: plastic, SS, or flange).
- Low Initial Pressure Drop: Optimized fiber structure reduces energy consumption during filtration.
- Customizable Sizes: Available in various diameters and lengths to match your existing equipment.

Frequently Asked Questions
Q1: Is this filter bag suitable for high-viscosity liquids like syrup?
Yes, the PE needle-felt material is designed to handle viscous fluids. The 5 micron rating allows a good balance between clarity and flow rate. For extremely thick syrups, we recommend a larger size bag or a pre-filter to extend service life.
Q2: Can I use this bag for hot sauce (up to 80°C)?
Absolutely. Our bag can operate continuously up to 90°C, making it suitable for hot-fill sauce production. However, sudden temperature changes should be avoided to prevent thermal shock to the felt.
Q3: What ring types are available?
We offer plastic sealing rings, stainless steel rings (SS304/316), and flange rings. The plastic ring is standard; SS rings are recommended for high-temperature or corrosive applications.
Q4: How do I know the correct size for my housing?
Please measure your housing’s inner diameter and length. Common sizes are #1 (180x430mm), #2 (180x810mm), #3 (102x230mm), and #4 (102x380mm). We can also produce custom sizes upon request.
Q5: Does this bag comply with food safety regulations?
Our bags are manufactured using FDA-compliant raw materials (21 CFR 177.1520). We can provide a certificate of compliance upon request. However, we do not claim CE or ISO unless specifically requested and verified.
Q6: What is the typical lifespan of the filter bag?
Lifespan depends on the solids load and operating conditions. For sauce filtration, a 5 micron bag typically lasts 4–8 hours of continuous use before needing replacement. We recommend using a differential pressure gauge to monitor when to change.
Q7: Can I order samples before bulk purchase?
Yes, we offer free samples (up to 5 pieces) for evaluation. You only need to pay for shipping. Contact our sales team to arrange.
Q8: What is the minimum order quantity?
Our MOQ is 100 pieces for standard sizes. For custom sizes, the MOQ is 500 pieces. Smaller quantities can be negotiated for trial orders.
