Many people think that aloneAir filterThe higher the filtering accuracy, the cleaner the filtered air, which is not correct. Filtration accuracy is only one of the factors that need to be considered when purchasing air filters. There are many manufacturers of air filters on the market. Therefore, the air filters appearing on the market are also diverse. Different filters have different materials., Operating principle, product performance and use, etc., are all different. So, what factors do we need to consider when purchasing air filters?
For places with high cleanliness requirements, customers should be advised to use non-clapboard high-efficiency air filters. In foreign countries, the price of air filters with partitions is higher than that without partitions. Therefore, there are not many places where air filters with partitions are used abroad. In addition, compared with the rectangular channel with a partition filter, the V-shaped channel without a partition filter further improves the uniformity of dust holding and prolongs the service life of the air filter. The working principle of the non-partition high-efficiency filter and the partition high-efficiency filter is similar.
This is also an important parameter to measure the performance of bag filter. Filtration wind speed is closely related to dust concentration, dust particle size, usage, viscosity, gas temperature, moisture content and dust removal methods. Partition type high efficiency filter is widely used in social life, and its superior performance makes itAir filterThe "pillar" product in.
However, it is more cost-effective to control the replacement cost of the filter element on the filter in a more accurate manner. Generally speaking, many people are not very clear about the internal structure of the air filter. In fact, whether the air can guarantee good filtration quality is very important for a good quality air filter.
The non-partition filter for ventilation can avoid the use of metal parts, easy to discard, and meet the increasingly stringent environmental requirements. Except for some special occasions that pay special attention to high temperature resistance and high safety requirements, the non-clapboard filter can replace the clapboard filter. The parameters of the filter can directly reflect the ability of the air filter to pass the air volume.
The conclusion drawn from measuring the filtration efficiency of high-efficiency air filters can be called "DOP efficiency". Colorimetry has been popular for many years and is a general ventilation filter test method. The partition plate is made of high quality kraft paper, hot rolling or offset paper. At present, the double-coated coated paper is used as the separator, and the main purpose is to prevent the cold, hot, dry and wet environment, which affects the shrinkage of the separator, thereby releasing tiny particles. But accordingAir filterThe manufacturer-Yantai Baoyuan Purification Co., Ltd. has many years of manufacturing experience. When the temperature and humidity change, this kind of separator paper may emit larger particles, causing the cleanliness test of the cleaning workshop to fail.
