Calculation method of air volume of HEPA filter
Guangzhou Rongteng Environmental Technology Co., Ltd. is a manufacturer specializing in the production of primary, medium and high-efficiency filters. It provides facilities for electronics factories, semiconductor companies, biopharmaceuticals, food processing, petrochemical industries, clean rooms, hospitals, automotive coatings and other industries. The required air purification solutions and filter products. The following is the filter manufacturer to introduce the calculation method of the air volume of the high efficiency filter. In fact, there are two different classifications of air volume calculation methods for high-efficiency filters: 1. Calculation method of standard separator filter 1. The section wind speed of the filter paper=1000/3600/25.27=0.011 m/s, that is, when the section wind speed of the filter paper is 0.011 m/s, the initial resistance of the filter paper is 200PA; 2. Next is the calculation of the air volume of the filter, a 900*600*370 filter 0.88*0.58*280*0.35*2*0.011*3600=3961m3/h, in which: 0.88 is the effective length of the filter paper; 0.58 is the effective width of the filter paper; 280 is the number of filter paper folds for a 1 meter standard filter; 0.35 is the actual height of the filter paper; 2 means double layer; 0.011 is the section wind speed of the filter paper; 3600 is one hour equal to 3600 seconds. 3. Next, we use a national standard 484*484*220 high efficiency filter to calculate: the rated air volume is 1000M3/H, the initial resistance is 200PA, the number of filter paper splits is 28 fold/10CM, and the effective area of the filter paper is calculated as 0.475*0.475*280 *0.2*2=25.27 square meters, in which: 0.47 is the effective length of the filter paper; 0.475 is the effective width of the filter paper; 280 is a 1 meter filter paper folded in double layers; 0.2 is the actual height of the filter paper. 2. Determine the air volume according to the wind speed and size of the high efficiency filter 1. Under normal circumstances, the high efficiency filter we use has a rated wind speed between 0.3-0.6M/S, and we can take the intermediate value 0.45; 2. To give a simple example, the size of the 1000 air volume high efficiency filter is: 484*484*220, and the air volume can be obtained by simply converting. These two are our common air volume calculation methods for high efficiency filters, because air volume is a very important knowledge when we use high efficiency air filters, so they must be mastered! The above is about the air volume counting of high efficiency filters Ways, if you want to know more about air filters, welcome to consult!
