The following parameters are common industry standard values. For specific models, please refer to the manufacturer's data sheet. Choosing the right medium efficiency bag air filter based on accurate parameters is crucial to ensuring air filtration effect, extending equipment service life and reducing operation costs.
Parameter Category | Typical Specifications/Description |
Efficiency Standard | European Standard EN779/ISO 16890: F5, F6, F7, F8, F9; American Standard ASHRAE 52.2: MERV 11, MERV 13, MERV 14, MERV 15 |
Filtration Efficiency | Take F7 grade as an example: Average counting efficiency for 0.4μm particles ≥ 80% - 90% |
Initial Resistance | 40 - 70 Pa (depending on model and rated air volume) |
Final Resistance | Recommended replacement resistance: 200 - 250 Pa |
Filter Media Material | Ultra-fine glass fiber, synthetic polyester fiber (PET), polypropylene (PP), etc., often with electrostatic enhancement for better dust capture performance |
Frame Material | Galvanized steel plate, aluminum alloy, stainless steel (for corrosion-resistant environments) |
Sealing Material | Polyurethane foam, neoprene rubber, EPDM rubber sealing strips |
Number of Bags | Commonly 4 bags, 6 bags, 8 bags. The more bags, the larger the dust holding capacity and the higher the applicable air volume. |
Common Sizes | Nominal sizes: 592 x 592 x 500 mm (24″ x 24″ x 20″), 595 x 595 x 500 mm; other custom sizes available |
Rated Air Volume | For example: 3400 m³/h (2000 CFM) @ 592x592x500mm (F7 grade) |
Selection & Replacement Tips
• Selection: The efficiency grade, size and number of bags of the filter should be comprehensively determined according to the total air volume of the system, the front-end filtration grade, the target cleanliness requirements and the installation space. Choosing the appropriate specification can avoid insufficient filtration effect or excessive energy consumption.
• Replacement: The filter should be replaced in a timely manner when its resistance reaches the recommended "final resistance" value, or when the filter bag is damaged or the seal is aged. It is recommended to install a differential pressure gauge in the air conditioning unit to monitor the resistance change and remind of replacement in time.
Medium efficiency bag air filters with different parameters are suitable for various scenarios such as central air conditioning systems, clean rooms, commercial ventilation and industrial process air treatment. Understanding these key parameters can help you make the most suitable choice and maximize the performance of the air purification system. For custom parameters and model details, please contact the manufacturer for professional advice.
