Remarks
① Air Permeability measured at ΔP = 200 Pa.
② Filtration Precision usually refers to the minimum particle size that can be effectively captured before dust cake formation. In practical use, filtration efficiency can be further improved by lowering filter velocity and allowing a stable dust layer to form.
③ MERV Grade tested according to ASHRAE 52.2 (USA) or EN779 (Europe).
★ All technical parameters are for reference only (test data may vary due to different conditions and equipment). We reserve the right to make changes without prior notice.
🔑 Key Advantages
- PPS: Best suited for low permeability, high precision filtration in high-temperature and chemically aggressive flue gas environments.
- Aramid: Ideal for higher airflow, antistatic properties, and thermal resistance in cement, steel, and other heavy industries.
👉 Both options are available with surface customization such as PTFE membrane, carbon impregnation, water & oil repellent, and flame-retardant treatments.
