Detail Information
Introduction
Key Features
>High-Temperature Resistance – Withstands continuous temperatures up to 260°C (500°F) and short-term peaks up to 280°C (536°F).
>Excellent Chemical Resistance – Highly resistant to acids, alkalis, and aggressive gases, making it ideal for extreme environments.
>Superior Filtration Efficiency – The fine fiber structure provides excellent dust capture, even for ultra-fine particles.
>High Dust-Holding Capacity – The multi-layer fiber structure traps more dust particles while maintaining airflow.
>Good Hydrolysis Resistance – More resistant to hydrolysis than aramid (Nomex®) but less than PTFE.
>Long Service Life – P84 filter bags have an extended operational life, reducing maintenance costs.
>Reduced Energy Consumption – Low pressure drop due to high permeability, leading to energy savings in dust collection systems.v
