Frequently Asked Questions (FAQ)
Q: How does P84 compare to fiberglass filter bags?
A: P84 offers better temperature resistance, anti-hydrolysis properties, and 50% longer lifespan, especially suited for high-humidity gases.
Q: Are anti-static treatments available?
A: Optional carbon fiber blends (surface resistance ≤10⁹Ω) eliminate explosion risks for flammable dust (e.g., coal, aluminum powder).
Q: How to identify bag failure?
A: Monitor sudden pressure drops or abnormal emissions. Professional leak testing every 6 months is recommended.
Q: What is the minimum order quantity (MOQ)?
A: Standard products: MOQ 50 bags; Custom designs: MOQ 100 bags. Trial orders are accepted.
