Introduction to the structural characteristics of flat plate primary air filters

flatbedPrimary air filtersIt is suitable for fresh air and return air filtration in air system, and pre-passing of local high-efficiency filtration device.

flatbedPrimary air filtersThe performance characteristics of the

1. The filtration efficiency for ≥5.0μm particles is 40%～60%.

2、Using special bulky high flux and low resistance chemical fiber cloth as filter material, with large dust holding capacity.

3. With galvanized steel, aluminum alloy or plastic outer frame.

Structural characteristics of flat plate primary air filters:

Assembled in the form of a pipe, with flanges at the front and rear, it is convenient to connect with the air ducts of the centralized air-conditioning system. Arrange and combine a number of filter units according to the required air volume, and leave an inspection door at the bottom (or side) of the filter section for maintenance and replacement of the filter.

The coarse and intermediate sections are only suitable for the filtration of fresh air.

The sub-high efficiency filtration section is characterized by high efficiency and low resistance. The initial resistance under the rated air volume is ≤90Pa, the filtration efficiency for dust particles above 0.5μm particle size is 95% (counting method), the filtration efficiency for atmospheric bacteria reaches 100%, and the final resistance is 200Pa. It is the ideal air purification equipment for computer rooms, hotels, gymnasiums, and other large-scale public places, and is also the ideal pre-filtering equipment for purification plants.

The high-efficiency filtration section is also characterized by high efficiency and low resistance. In the rated air volume of the initial resistance of ≤ 120 Pa, the particle size of 0.5 μm dust particles above the efficiency of 99,95% (counting method), the bacterial filtration efficiency of atmospheric bacteria up to 100%, the end of the resistance of 300 Pa, is the computer room and cleanliness requirements of the place of the ideal air purification equipment, but also clean room (class 10,000 below the clean room) is the ideal terminal filtration equipment. It is also the ideal terminal filtration equipment for clean room (below class 10,000 clean room).

Air filter, installed in the air conditioning system in the middle of the air supply pipeline, coarse and medium air filtration section as a pre-filtering equipment, play a good role in protecting the high-efficiency filters and anechoic. High-efficiency filtration section should be installed with the front-end pre-treatment filtration equipment, while the muffling effect is better.
