FAQs: Technical Q&A for F7 Synthetic Filter Media

1. What are the main materials used for Medium Efficiency F7 Synthetic Air Bag Filter Media?

High-purity synthetic fibrous polymers, primarily melt-blown polypropylene (PP) and polyesters (PET), engineered for fine particulate filtration, thermal/bio-stability, and flame retardancy.

2. What is the mean filtration efficiency and which standard applies?

EN779:2012 F7 = 80%-90% filtration at 0.4μm dust, equivalent to ISO16890 ePM2.5: 65-75% — certified by third-party labs.

3. What is the recommended installation standard for bag filters made from this media?

Follow EN1886 (filter housing), seal all mounting surfaces, and never over-compress the media (preserves pore structure and service life).

4. How does thickness/basis weight affect pressure drop?

Higher basis weight often boosts loading capacity but may increase pressure drop. F7 Synthetic Media is optimized to balance both (e.g. 5.0mm, 270 g/m²: ~60Pa at 0.5 m/s).

5. How do I confirm if the media is truly glass-free?

Request the manufacturer’s MSDS, check for EN779/ISO16890 glass fiber exclusion statements, and conduct SEM microstructure analysis if in doubt.

6. What fire/safety standards must be met?

Minimum F1 rating under DIN53438 for fire-retardant certifications; suitable for most EU/US commercial facility codes.

7. What is the service life or replacement period?

Typical replacement: 9–18 months, depending on airborne particle load; end-of-life defined by pressure drop ≥ twofold initial value or efficiency below 80%.
