Centrifuge Bags
Overview
Centrifuge filter bags are precision-engineered textile liners designed for solid-liquid separation in centrifugal filtration systems. These bags line the internal basket of centrifuges, capturing solids while allowing liquid to pass through, ensuring clean separation, efficient discharge, and protecting equipment.
At Filtech Textiles, we manufacture high-performance centrifuge bags using durable, chemically-resistant filter media tailored to meet the demands of various industries and centrifuge models.

Types of Filter Media Used in Centrifuge Bags
| Material | Micron Rating | Advantages | Limitations |
|---|---|---|---|
| Polypropylene | 1 – 200 µm | Excellent chemical resistance, economical | Limited heat resistance (~90°C) |
| Polyester (PET) | 1 – 150 µm | Strong, heat-resistant (up to 150°C), durable | Moderate chemical compatibility |
| Nylon (Monofilament) | 10 – 300 µm | Reusable, high tensile strength, smooth discharge | Costlier, not for fine filtration |
| Cotton | 50 – 200 µm | Traditional use, cost-effective | Absorbs moisture, limited durability |
| PTFE (Teflon) | 1 – 100 µm | High-end, chemical and heat resistant (up to 260°C) | Expensive, used in critical applications |
