HVAC Systems ‌Cleanrooms Industrial‌ Medium-Efficiency Pleated Air Filters

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

1. ‌By Frame Material‌
   • ‌Aluminum‌: Lightweight, corrosion-resistant.
   • ‌Galvanized Steel‌: Durable for industrial use.
2. ‌By Pleat Configuration‌
   • ‌Standard Pleats‌: Balanced filtration and airflow.
   • ‌High-Density Pleats‌: Higher dust capacity but slightly higher resistance.
3. ‌Sealing Options‌
   • ‌Double-Lip Gaskets‌: Ensures airtight fit in HVAC systems.
