| Filter "filter efficiency" is arrested with the amount of dust-filter into the air dust concentration in the ratio: Filtration efficiency = Filter and trap dust volume = 1 -- The lower reaches of dust concentration in air The upper reaches of dust concentration in air The upper reaches of dust concentration in air In deciding factor in the efficiency of the filter, dust, "volume" in a wide range, which measured and calculated by the efficiency of the filter value is varied. Practical, dust weight, quantity, concentration, the quantity of concentration; there is a single particle dispersed phase (the same size) of some kind, how the amount of particles dispersed phase; indirectly determine the weight of the dust-light (colorimetric Law), fluorescent volume (fluorescence); there is a transient state, there is the whole process of the weighted average volume. Filter efficiency and value of the test are closely related. On the same filter used in different ways to test the efficiency of the measured value will be different. Country, the manufacturers do not use uniform testing method, the filter efficiency of the interpretation and expression of different. Historically, the traditional air filter (air-conditioning and ventilation filters, clean room filters) and other products that filter and dust collector manufacturer of the product does not belong to a Huoer, they said the difference much efficiency . When the filter cleaner production, or the development of plant dust filter, they will be talking about the efficiency of their value confused. To leave the test on the efficiency out of the question. In order to facilitate and reduce misunderstanding, some with signs that the efficiency of the method, in which both test methods, but also to determine the efficiency indicators, see the "common identification system" and "comparison chart." Today, the world's filters are diverted to the Chinese market, a wide range of efficiency and effectiveness of numerical terms so that users, designers and manufacturing Yunshanwuzhao. If you need to clear the efficiency of the specific values must be at the same time a clear determination of the value of efficiency. |
