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).
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.
