Selection and Application of Medium-Efficiency Filters

1.Performance Characteristics of Medium Efficiency Filters

Medium-efficiency filters primarily intercept particulate matter with sizes ranging from 1 to 5 μm, achieving a filtration efficiency of 40-60% (for particles between 0.4-1 μm) and an initial pressure drop of approximately 50-80 Pa.

2. Common Structural Forms

- Bag filter: Large filtration area, high dust-holding capacity

- Plate filter: Compact structure, easy installation

Key selection criteria:

- F5-F9 grades in the EN779 standard

- The balance between filtration efficiency and pressure drop

- Filter material (glass fiber/synthetic fiber)

3. Main Application Areas

- General Hospital Area

- General Clean Area in Pharmaceutical Manufacturing Plants

- Assembly Workshop of Electronic Factory

- Food Processing Plant
