P84 Dust Collector Filter Bags
P84 (Polyimide) filter bags are made of 100% imported polyimide fibers with distinctive trilobal cross-section, offering exceptional high-temperature resistance and chemical stability. They are the top choice for harsh flue gas conditions in waste incineration power plants, coal-fired boilers, cement kiln head/tail, steel smelting, hazardous waste incineration, and non-ferrous metal processing.

FAQ (Frequently Asked Questions)
Q1: P84 vs PPS filter bags – which one should I choose? A: Choose PPS when temperature ≤220°C (most cost-effective); choose P84 when temperature ≥260°C. Waste incineration, hazardous waste incineration, carbon black tail gas and other high-temperature plants almost exclusively use P84 because PPS ages and becomes brittle rapidly above 280°C.
Q2: Can P84 bags really last over 3 years? A: Yes – real cases have exceeded 40 months! The key factors are: ① Flue gas temperature strictly controlled below 380°C ② Regular low-pressure pulse cleaning ③ Inlet dust concentration <800g/Nm³ ④ We provide free working condition analysis – if lifespan is less than agreed, full compensation guaranteed.
Q3: Can you send samples for testing? A: Yes! We provide 3 free sample bags (standard 160×6000mm). You only pay express freight. Test for 30 days – full refund if not satisfied.
Q4: What’s the difference between laminated (PTFE membrane) and non-laminated P84 bags? A: Huge difference! • Non-laminated: emission 30–50 mg/Nm³, slightly lower pressure drop • PTFE laminated: emission <5–10 mg/Nm³ (ultra-low emission mandatory), initial ΔP only 80–100 Pa higher, actually lower after 1 month of running.
