4.Recommended working temperature: ≤80°C, humidity ≤100%RH
5.Initial resistance: ≤40–55 Pa
6.Suggested final resistance: ~110–250 Pa
7.Number of bags/size: Common 6 bags, sizes such as 595×595×600 mm, and 3 bags; height 381–600 mm
8.Dust capacity: 300–1000g
Medium Efficiency Bag Filter specifications
| specifications | F5 | F6 | F7 | F8 | F9 |
| Filtration efficiency | 40–60% | 60–80% | 75–85% | 85–90% | ≥95%@1 µm |

| Frame size | 592×592mm, 592×287mm, etc. | ||||
| Bag depth | 280–600 mm, 3–10 bags | ||||
| Filter material | Synthetic fiber or glass fiber | ||||
| Material temperature | ≤70–80°C | ||||
| Dust-resisting ability | F7 ≥600g/m² | ||||
| standard | EN 779 / ISO 16890 / GB/T14295 |
Application scenarios
1.Ventilation and air conditioning in office buildings, shopping malls, etc.: initial effect + medium effect combination to improve air quality;
2.Hospital and clean room: medium-effect bag type (F8–F9) with efficient terminals to ensure cleanliness requirements;
3.Industrial factory: First use initial protection and medium-effect filter dust to improve system reliability.
Select suggestions
1.Practical use:
Initial effect (G3/G4): suitable for pre-filtering;
Medium-effect (F5–F9): used for fine particle filtration, efficient pre-position;
2.Size matching: Common sizes include 595×595×381/600 mm, 3–10 bags;
3.Resistance control: Low initial resistance can save energy, and high-efficiency protection standards are selected for final resistance;
4.Filter material selection:
Polyester is more resistant to washing;
Glass fiber is more resistant to high temperatures;
5.Dust and replacement cycle:
Initial washable or replacement cycle 1–3 months;
The medium-effect usage cycle is about 6 months, and the replacement reaches final resistance based on the pressure drop.
