Key Features & Technical Specifications
- Dual-Layer Construction: Polypropylene (PP) fused with Nylon (Polyamide) for superior chemical resistance and mechanical strength.
- High Filtration Precision: Available from 1 micron up to 500 microns, ensuring consistent solid-liquid separation for your process.
- Seamless Weave Technology: No loose threads or weak points – reduces particle bypass and extends bag life.
- Temperature Endurance: PP withstands up to 90°C, Nylon up to 120°C, ideal for hot chemical slurries.
- Customizable Dimensions: We produce bags to fit any rotary basket centrifuge model – just provide your basket dimensions.
- Reinforced Openings: Options include stainless steel clamp rings, drawstrings, or snap rings for secure, leak-proof mounting.
- Easy Cleaning & Reuse: Many bags can be washed and reused, reducing waste and consumable costs.

Advantages for Your Chemical Process
- Reduced Filter Cake Moisture: The dual-layer structure allows faster drainage, leading to drier solids and lower drying costs.
- Minimized Downtime: Bags are easy to install and remove, and their durable construction resists tearing even under high centrifugal forces.
- Versatile Chemical Compatibility: PP + Nylon resists a wide range of aggressive chemicals, including hydrochloric acid, sodium hydroxide, and organic solvents.
- Cost-Effective Operation: Reusable designs (up to 10–20 cycles depending on application) lower your per-batch filtration cost.
- Contamination-Free Filtration: No fiber shedding – our bags are manufactured with thermally bonded edges to prevent particle release.
- Custom Engineering: We offer free consultation to recommend the optimal micron rating, fabric weight, and bag geometry for your specific centrifuge model and slurry properties.

Frequently Asked Questions
-
Q: What is the difference between PP and Nylon filter bags?
A: PP (polypropylene) offers better chemical resistance to acids and alkalis, while Nylon (polyamide) provides higher temperature tolerance and mechanical strength. Our hybrid bags combine the best of both worlds. -
Q: Can I reuse these filter bags?
A: Yes, many of our bags are designed for multiple uses. The number of reuse cycles depends on the chemical exposure and solid particle abrasiveness. Typically, you can achieve 10–20 cycles before replacement. -
Q: How do I determine the correct micron rating for my application?
A: We recommend based on the particle size distribution of your solids. For coarse separation (e.g., >100 µm), choose 100–500 µm; for fine filtration (e.g., 1–50 µm), select finer ratings. We can test your slurry sample to advise. -
Q: What closure type is best for a rotary basket centrifuge?
A: Stainless steel clamp rings are most common for easy installation and secure fit. Drawstrings are suitable for smaller bags, and snap rings are used for high-speed centrifuges. We will help you choose based on your centrifuge design. -
Q: Do you offer custom sizes?
A: Absolutely. We can manufacture bags to any dimensions – please provide your basket diameter, height, and any special shape (flat bottom, conical, etc.). -
Q: What is the typical lead time?
A: For standard sizes, lead time is 7–15 days. Custom orders generally require 15–25 days, depending on quantity and complexity. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer free samples (shipping charges may apply) for your evaluation. Contact us with your requirements. -
Q: How do you package the filter bags for export?
A: Each bag is individually packed in a poly bag, then packed in cartons or woven bags, with palletization upon request. We ensure safe transportation to any port.
