Automatic roller shutter filter

1. It varies from region to region. Pollution in the north is more serious than in the south, because there is less vegetation in the north.Automatic roller shutter filterThe speed of filter replacement will be faster. For example, in winter in Shijiazhuang, the filter material is wound once a week or so, and the filter cotton with a height of 3 meters and a length of 15 meters needs to be replaced in more than a month; while in Guangzhou, it is only wound once a month. Can be used for half a year. differ greatly.


2. Varies due to different seasons. The pollution is more serious in winter than in summer. In summer, because of more precipitation and more water vapor content in the air than in winter, a lot of dust is sent back to the ground, and the air quality is better. Moreover, summer is not as cold and dry as winter monsoons, and there is less dust. Therefore, the summer filter material can be used longer.


3. In addition, the environmental conditions in some areas will also be affected. For example, there are large local coal metallurgical enterprises or long-term civil construction projects, which will cause the PM2.5 value to be too large, and the main pollutant in the air-dust will increase. In this way, the time used by the cotton filter will naturally differ between two adjacent places.


4. In addition,Automatic roller shutter filterThe time of filter replacement is also related to the value set by the differential pressure switch. The factory setting of Shandong snyli Purification is 100~150Pa, and the time for 100Pa filter cotton is shorter than that of 150Pa. This should be adjusted according to the needs of the owner.
