Metamax Filter Bag
Metamax Filter Bag
A high-performance filter media engineered for extreme thermal stability and chemical resistance. Leveraging Metamax fiber, it delivers exceptional temperature resistance, outstanding dimensional stability, fire retardancy, and chemical durability.
Core Advantages
Exceptional Temperature Resistance: Continuous 204℃ operation (instant 240℃ peak, withstanding 250℃ fluctuations).
Outstanding Dimensional Stability: <1% thermal shrinkage at 250℃, ensuring long-term structural integrity.
Fire Retardancy: Self-extinguishing (LOI 30), non-combustible up to 400℃.
Chemical Durability: Resists low-concentration acids/alkalis and most hydrocarbons, including minor fluorides.
Performance Benefits
Exceptional chemical resistance to acidic and oxidative environments
Customizable for any application requirements
High dust-holding capacity and low pressure drop
Compliant with international quality and safety standards
Key Applications
Widely used in high-temperature dust collection for:
Asphalt Mixing
Cement Kilns
Steel Smelting
Non-Ferrous Metal Refining
