High Effiency Catalytic Filter Bag


High Efficiency Catalytic Filter Bag


l   Multi-layer Structure for Longer Reaction Time and Higher Efficiency

The internal layer contains a high catalyst load. Its thicker catalytic layer extends reaction time (0.35–1s), delivering higher conversion and removal efficiency than other brands at the same filtration velocity.


l   Multi-functional Catalyst

Proprietary formulation enables DeNOx at medium/low temperatures and decomposition of dioxins and VOCs.


l   Integrated Treatment

With upstream alkaline and reducing agents, the system removes acid gases, dust, SO, NOx, and dioxins in one process.

Catalytic Filter Bag – Advantages & Size Dimension


l   Selected hydrophobic, hydrolysis-resistant, and breathable customer-specified materials. Resistant to acidic and alkaline gases

l   High catalyst loading; excellent removal efficiency

l   Anti-deformation: withstands >200,000 pulse-cleaning cycles

l   Long abrasion life: filter bags and cages do not suffer multi-point wear damage from continuous friction

l   ESG-oriented product supporting environmental sustainability

l   Dimensions vary based on equipment type, gas flow rate, operating temperature, and required filtration efficiency.

l   Custom diameters and lengths available upon request.

l   Catalyst type:

FB-01 (low-temp catalytic filter bag): for deNOx 120~200°C

FB-02 (mid-temp catalytic filter bag): for deNOx 175~250°C, for Dioxin removal 175~230°C

Dual DeNOx and Dioxin Removal Efficiency


Middle temperature Catalytic Filter Bag-deNOx efficiency



Dioxin Removal Efficiency


With vanadium-based catalysts, dioxins react with oxygen and decompose into non-toxic substances such asCO2, H2O, and HCl.

Reaction (oxidation): C12HnCl8-nO2+(9+0.5n)O2=(n-4)H2O+12CO2+(8-n)HCl
