Medium efficiency bag filter is a type of medium efficiency filter mainly used in air conditioning systems. Mainly using high-quality materials with a large dust holding capacity. Used for filtering dust particles of 1-5 meters, it has the advantages of low resistance and high air volume.

Characteristics of medium efficiency bag filters

1. Frame material: aluminum profile, galvanized sheet frame

2. Sealing agent: polyurethane adhesive

3. Filter materials used: glass fiber filter paper, high-quality synthetic non-woven fabric filter material

4. Partition: Hot melt adhesive

5. Working environment: temperature range and humidity range

6. Sealing strip: chloroprene rubber

7. Efficiency: G3, G4, F5, F6, F7, F8, F9. Suitable for different occasions

The factors that affect the filtration efficiency of medium efficiency bag filters are as follows:

1. The efficiency of the medium efficiency bag filter is determined according to indoor cleaning standards, and the combination series and efficiency of each level of filter should be reasonably selected. If general purification is required indoors, a main filter can be used; If indoor requirements are for medium purification, primary and secondary filters should be used; If the indoor requirement is for ultra purification, primary and medium efficiency three-stage purification filters should be used, and the efficiency of each filter should be reasonable and matched properly. If the efficiency of two adjacent filters is too poor, the former should be used. One filter cannot protect two filters.

2. The medium efficiency bag filter accurately determines the dust content and dust characteristics of outdoor air. Because filters are designed to filter and purify outdoor air entering the room, the dust content in outdoor air is a very important data. Especially in multi-stage purification and filtration processes, the selection of pre filters should consider factors such as environment, spare parts costs, operating energy consumption, maintenance, and supply.

3. Filters can accurately determine the characteristics of filters. The main characteristics of a medium efficiency bag filter are filtration efficiency, resistance, permeability, dust capacity, filtration air speed, and processing air volume. Under permissible conditions, filters with high efficiency, low resistance, large dust holding capacity, moderate filtration speed, large air processing capacity, easy manufacturing and installation, and low cost should be selected as much as possible. When selecting a filter, it is necessary to conduct an economic analysis of the performance and energy efficiency ratio of one and multiple filters.

4. Analyze the characteristics of dust gas. The main characteristics of dusty gases related to filter selection are temperature, humidity, acid, alkali, and the amount of organic solvents. Due to the fact that some filters allow for use at high temperatures, while others can only operate at room temperature and humidity, the acidity and alkalinity in dusty gases and organic solvents can affect the performance and efficiency of medium efficiency bag filters.

In summary, when the size and pocket length of the medium efficiency bag filter are the same, as the efficiency increases, the dust absorption capacity gradually decreases. But you can't wait until the bag is filled with dust to mistake it for a replacement. This bag is not meant to 'fix' things.
