Medium-Efficiency Pleated Air Filters (MEPAF)
Medium-efficiency pleated air filters (MEPAF) are designed to capture particles between 1-5μm (e.g., fine dust, mold spores, pollen) with an efficiency of 40%-90% (EN779 standard: F5-F9). They are widely used in HVAC systems, cleanrooms, and industrial air purification setups.
Key Features & Benefits
- Filtration Efficiency:
- F5-F7: 40%-70% (EN779) for general commercial use.
- F8-F9: 70%-90% for high-demand environments (hospitals, labs).
- Dust-Holding Capacity: Pleated design increases surface area, extending lifespan.
- Low Pressure Drop: Maintains airflow while reducing energy consumption.
Types & Design
- By Frame Material
- Aluminum: Lightweight, corrosion-resistant.
- Galvanized Steel: Durable for industrial use.
- By Pleat Configuration
- Standard Pleats: Balanced filtration and airflow.
- High-Density Pleats: Higher dust capacity but slightly higher resistance.
- Sealing Options
- Double-Lip Gaskets: Ensures airtight fit in HVAC systems.
