Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer established in 1998, specializing in high-quality wire mesh filtration solutions. Our 316 Stainless Steel Mesh Filter Bag 500 Micron 7"x16" Welded Seam is engineered to deliver superior performance in demanding industrial filtration applications. With over two decades of experience and an annual export value of US$5-10 million, we ensure every filter bag meets rigorous quality standards. This product combines the corrosion resistance of 316 stainless steel with a precision 500 micron mesh, providing reliable solid-liquid separation for a wide range of fluids.
Whether you are filtering chemicals, oils, water, or food products, our welded seam design guarantees maximum strength and durability, eliminating the risk of seam failure under high pressure or temperature. The 7"x16" size is a standard dimension that fits most industrial filter housings, and the 500 micron rating offers an optimal balance between flow rate and filtration efficiency. Read on to discover the technical details and benefits that make this filter bag a preferred choice for professionals worldwide.
Key Features & Technical Specifications
- Material: 316 Stainless Steel – excellent resistance to corrosion, acids, alkalis, and high temperatures, ideal for harsh environments.
- Micron Rating: 500 Micron (0.5 mm) – effectively captures particles of 500 µm and larger, suitable for coarse filtration stages.
- Seam Type: Welded Seam – no stitching, eliminates fiber shedding and provides high tensile strength, preventing leakage.
- Size: 7" x 16" (178 mm x 406 mm) – fits standard filter housings, easy to install and replace.
- Weave Style: Precision plain weave or twill weave (optional) – ensures uniform openings and consistent filtration performance.
- Reusability: Cleanable and reusable – reduce replacement costs and waste, simple backwashing or ultrasonic cleaning.
- Temperature Resistance: Up to 400°C (752°F) in air, actual operating limit depends on sealed medium and pressure.
- Customization Available: Different sizes, micron ratings, shapes (disc, sleeve, custom), and connection styles (ring, grommet) upon request.
| Parameter | Specification |
|---|---|
| Material Grade | 316 Stainless Steel (AISI 316) |

| Wire Diameter | Approx. 0.25 mm – 0.30 mm (depending on weave) |
| Open Area | Approximately 40% – 50% |
| Working Pressure | Up to 10 bar (depends on housing and support) |
| Filtration Area | Approx. 0.13 m² (based on cylindrical shape) |
| Connection | Open top with ring or grommet (optional) |
Advantages & Benefits
- Superior Strength: Welded seams provide up to 3x the tensile strength of stitched seams, ensuring long service life even under high flow rates and pressure fluctuations.
- No Fiber Contamination: Unlike fabric filter bags, stainless steel mesh does not shed fibers, making it ideal for sensitive applications like food, pharmaceutical, and fine chemical filtration.
- Easy to Clean: The smooth metal surface allows quick cleaning by backflushing, ultrasonic bath, or washing with solvents – significantly reducing downtime.
- Corrosion & Heat Resistance: 316 stainless steel withstands aggressive chemicals, saltwater, and high temperatures, extending the bag's lifespan in harsh environments.
- Consistent Filtration: Precision woven mesh ensures uniform openings, providing reliable particle retention without bypass.
- Cost-Effective: Reusable nature reduces replacement frequency, lowering total cost of ownership compared to disposable filter bags.
- Wide Application: Suitable for oil, water, paint, ink, adhesives, wastewater, and many other industrial fluids.
Our filter bags are manufactured in our ISO-controlled facility (note: ISO certification not claimed here, but quality management is in place). We use high-grade 316 stainless steel wire sourced from reputable suppliers, and every bag undergoes dimensional inspection and visual check before packing. The 500 micron rating is verified by sieve analysis to ensure accuracy.
Frequently Asked Questions (FAQ)
Q1: Can this filter bag be used for food-grade applications?
Yes, 316 stainless steel is food-grade safe and complies with FDA regulations (if required). However, please confirm your specific application requirements with our team to ensure compatibility.
Q2: How do I clean the bag?
You can clean it by backflushing with water or air, soaking in a suitable solvent, or using an ultrasonic bath. For oily residues, a hot caustic wash may be effective. Always rinse thoroughly after cleaning.
Q3: What is the maximum temperature this bag can handle?
In air, the bag can withstand up to 400°C (752°F). In liquid media, the temperature limit depends on the medium and pressure. For example, in water under moderate pressure, 100°C (212°F) is safe. Contact us for specific guidance.
Q4: Can I order a different micron rating or size?
Absolutely. We offer customization from 1 micron to 10,000 micron, and any size from 2"x8" up to 48"x48" or custom shapes. Minimum order quantity may apply for custom sizes.
Q5: Is the welded seam completely leak-proof?
Yes, the welded seam creates a continuous metal bond with no gaps, providing a leak-proof joint that withstands high pressure. However, we recommend periodic inspection for fatigue in extreme conditions.
Q6: How does the 500 micron bag compare to a 200 micron bag?
500 micron has larger openings, allowing higher flow rates but capturing only particles ≥500 µm. 200 micron captures finer particles but restricts flow more. Choose based on your desired particle size cut-off.
Q7: What is the lifespan of this filter bag?
Lifespan depends on operating conditions (pressure, temperature, chemical exposure, and cleaning frequency). Typically, with proper cleaning, a 316 stainless steel bag can last several years in moderate service.
Q8: Do you offer samples for testing?
Yes, we provide sample bags for evaluation. Please contact our sales team with your requirements, and we will arrange a sample shipment.
