Calculation method of air volume of high efficiency filter with partition

First, the first calculation method of the air volume of the high-efficiency filter with a partition: a 484 * 484 * 220 high-efficiency filter to calculate the rated air volume is 1000M3 / H, the initial resistance in 200PA, the number of filter paper splitting 28 fold / 10CM, the effective area of the filter paper calculation: 0.475 * 0.475 * 280 * 0.2 * 2 = 25.27 square meters, of which. 0.475 for the effective length of the filter paper, 0.475 for the effective width of the filter paper, 280 for the number of 1 meter of filter paper folding, 0.2 for the actual height of the filter paper, 2 for the double layer, the filter paper section wind speed = 1000/3600/25.27 = 0.011 m / s, that is to say, when passing through the cross-section of the filter paper wind speed of 0.011 m / s when the filter paper in the initial resistance of 200PA.




Second, the filter air volume, a 900 * 600 * 370 filters 0.88 * 0.58 * 280 * 0.35 * 2 * 0.011 * 3600 = 3961m3 / h, of which 0.88 for the effective length of the filter paper, 0.58 for the effective width of the filter paper, 280 for the standard filter paper folding number of 1 meter, 0.35 for the actual height of the filter paper, 2 for the double layer. 0.011 for the filter paper section wind speed, 3600 for an hour is equal to 3600 seconds which is a standard high-efficiency filter with a partition air volume calculation method!




According to the high-efficiency filter wind speed and size to determine the air volume, in general, we use high-efficiency filters, with rated wind speed between 0.3-0.6M/S, we can take the middle value of 0.45, to give a simple example, 1000 air volume of high-efficiency filters size is: 484*484*220, only need to be converted to derive the air volume, these two are our common! These two are our common methods of calculating the air volume of high-efficiency filters.
