Comparison of Different Filter Bag Fabrics in Baghouse Systems
The type of filter fabric used in baghouse systems directly affects filtration efficiency, bag lifespan, and overall system performance. Since each process involves different types of particles, temperatures, and humidity levels, selecting the appropriate fabric for each application is crucial. In this article, we compare the most commonly used filter bag fabrics in the industry.
- Polyester (PET)
The most widely used filter bag fabric. Operates effectively at temperatures up to 135°C. Offers good chemical resistance but is limited in acidic environments.
Applications:
- Metal processing
- Woodworking
- Cement bagging lines
Advantages:
- Cost-effective
- Wide application range
- High mechanical strength
- Polypropylene (PP)
Highly resistant to moisture and alkaline environments. Can be used up to 90°C. Preferred in chemical processing applications.
Applications:
- Food industry
- Chemical industry
Advantages:
- Resistant to acids and alkalis
- Suitable for low-temperature applications
- Aramid (Nomex)
Thanks to its high heat resistance, it can be used safely in applications up to 200°C. Offers excellent thermal stability.
Applications:
- Cement kiln outlets
- Asphalt plants
Advantages:
- Heat-resistant
- Resistant to thermal shock
- PPS (Polyphenylene Sulfide)
Has high chemical resistance to both acidic and basic environments. Can withstand up to 190°C. Maintains performance even in humid conditions.
Applications:
- Thermal power plants
- Chemical plants
Advantages:
- Excellent chemical resistance
- Moderate resistance to oxidation
- PTFE (Teflon)
Offers the highest resistance to both chemicals and heat. Can operate up to 260°C. Though more expensive, it is ideal for harsh processes.
Applications:
- Processes involving hazardous gases
- Pharmaceutical and chemical industries
Advantages:
- Maximum temperature and chemical resistance
- Long service life
