Description
Introduction
Key Features
>Exceptional High-Temperature Resistance – Can withstand continuous temperatures up to 260°C (500°F) and short-term peaks up to 280°C (536°F).
>Unmatched Chemical Resistance – Resistant to acids, alkalis, organic solvents, and corrosive gases, making it ideal for highly aggressive environments.
>Outstanding Filtration Efficiency – Fine-pore structure and PTFE membrane options provide superior dust capture while maintaining low pressure drop.
>Superior Non-Stick & Self-Cleaning Properties – PTFE naturally repels dust and moisture, reducing filter clogging and extending service life.
>Best Oxidation & Hydrolysis Resistance – Unlike PPS or aramid (Nomex®), PTFE resists oxidation and degradation in humid or high-oxygen environments.
>Long Service Life – PTFE filter bags can last 3–5 times longer than standard filter materials, reducing maintenance costs.
>Low Friction & Minimal Dust Retention – Ensures consistent airflow and prevents dust buildup in baghouse dust collectors.
