Product Description: Air Purification System Waste Incineration PTFE Dust Collector Bag Filter
Core Features and Advantages
High-Efficiency Filtration Performance
Material: Made of 100% PTFE (Polytetrafluoroethylene) base fabric with a PTFE membrane layer, ensuring filtration precision and stability.
Filtration Efficiency: ≥99.995% retention rate for particulates ≥0.1 microns, with a dynamic dust removal rate of 99.995% and a static dust removal rate of 99.999%, meeting waste incineration flue gas emission standards (EU 2000 standard ≤10 mg/m³).
Air Permeability: Air permeability of 20–45 L/(m²·s) @200Pa, balancing filtration efficiency and pressure drop to reduce system energy consumption.
High-Temperature and Corrosion Resistance
Continuous Operating Temperature: 250°C (some models up to 260°C), with an instantaneous peak temperature of 280°C, suitable for high-temperature flue gas from incinerators.
Chemical Stability: Resistant to strong acids, alkalis, and organic solvents, making it ideal for purifying flue gas containing corrosive gases such as HCl, HF, and SO₂.
Sealed Back Panel and Structural Optimization
Double-Layer Lockstitch Seaming: Utilizes an advanced international double-layer interlocking stitching structure to prevent unraveling and deformation, extending filter bag lifespan.
Sealed Design: Equipped with stainless steel elastic bands at the bag opening for a tight fit with the tube sheet, preventing air leakage and ensuring filtration efficiency.
Durability and Maintenance Cost
Service Life: ≥4 years (24-hour daily operation), significantly longer than the 1–2 years of standard filter bags.
Low Failure Rate: <1% failure rate in the first 3 years and <5% in the 5th year, reducing replacement frequency and downtime losses.
Hydrolysis Resistance: While hydrolysis resistance is moderate, it is partially compensated by membrane coating, making it suitable for dry or semi-dry flue gas conditions.

Recommendation
If you manage waste incineration, hazardous waste treatment, or high-temperature industrial dust removal projects and aim for:
Ultra-Low Emissions: Meeting stringent EU or domestic environmental standards (dust ≤10 mg/m³).
Long-Term Stability: Reducing filter bag replacement frequency and lowering lifecycle costs.
Harsh Condition Adaptability: Withstanding high temperatures, corrosion, and condensation to avoid frequent shutdowns.
This PTFE membrane filter bag is the ideal choice. Its sealed design, high-efficiency filtration, and durability significantly enhance system reliability, particularly in high-capacity, high-emission-requirement scenarios.
