What Is a PTFE (Teflon) Filter Bag?
PTFE (Teflon) filter bags are specifically engineered for industrial processes that involve extremely high temperatures and aggressive chemical environments. While Nomex filter bags offer continuous operation up to 200°C, PTFE filter bags can withstand temperatures up to 260°C, making them ideal for extreme conditions.
The key feature of these filter bags is their multifilament PTFE internal structure, which allows them to resist high temperatures while maintaining excellent chemical stability. Additionally, they are heavier than standard filter bags, with a weight of approximately 750 grams per square meter, enhancing their durability and mechanical strength.
Core advantages of PTFE filter bags include:
- Exceptional high-temperature resistance (up to 260°C)
- Excellent chemical resistance (acid, alkali, solvent, oxidant, hydrolysis)
- High structural integrity and weight
- Anti-stick surface that prevents dust accumulation
Where Are PTFE (Teflon) Filter Bags Used?
PTFE filter bags are recommended for use in filtration systems that deal with high-temperature and chemically aggressive dust particles. Rather than associating usage with specific industries, a more effective approach is to analyze the process conditions unique to each facility.
They are especially suited for:
- Filtration of extreme-temperature process gases
- Systems with high concentrations of acids or alkalis
- Solvent and oxidant-rich environments
- Manufacturing lines requiring high chemical and thermal resistance
In such demanding applications, standard filter bags may degrade quickly, whereas PTFE filter bags ensure long-term, reliable filtration performance.
