EfficientAir filterThe replacement cycle should be determined according to the mode of use. When installing a high-efficiency air filter in a clean room, the operating time and exhaust volume data should be accurately counted. This is a reliable basis for replacing high efficiency air filters. Under normal operation, the service life of the high efficiency air filter can reach more than 1 year. If reasonable maintenance can be carried out, the service life of the high-efficiency air filter can reach more than 2 years. Of course, the quality of the filter should also be considered.

The replacement cycle of the filter should be determined according to the installation environment. For example, the service life of a high efficiency air filter in an air cleaning apparatus is different from that in a simple environment. For example, high-efficiency air filters used in the electronics industry can extend their service life if they are maintained in a better way. The filter installed in the air shower can be used for 2 years. Usually, the filter will have a differential pressure gauge or wind speed level in use to determine a better replacement time. The decision may also be made according to the actual usage pattern. During use, check the material on the surface of the HEPA filter outlet. If there is a lot of dust, prepare to replace them. The color of the filter material on the upper and lower sides can also be used as the basis for replacement. If both parties turn black, they should also be ready to replace. The use of indoor air filters can be carried out many times during use, and time analysis can be carried out after summary to ensure the replacement cycle. If the cleanliness of the clean room does not meet the requirements, it can also be replaced.

Common high-efficiency air filters are basically replaced once a year to two years, but they should not be determined according to the actual use environment. Of course, it is not allowed to arbitrarily increase the scope of application in use. If the design and installation are unreasonable, the fresh air system is not perfect, and the control scheme of the clean room is unreasonable, then its service life will also be affected, and the replacement cycle will be shortened in this case.

HEPA filters can be used not only in biomedicine, but also in precision instruments, as well as in the current beverage, food and printing industries. Because there is a common place in these industries is the demand for dust-free purification space, the installation of filters can better achieve a dust-free state. Of course, there are many kinds of high-efficiency air filters, and the products need to be selected according to the actual use, depending on the environment. High efficiency air filter manufacturers will conduct tests to ensure the effectiveness of use. Moreover, this filter not only has a high-efficiency filtering function, but also has the characteristics of low resistance and large dust capacity, which also meets the needs of different users.

An air filter is a device that collects dust from the gas-solid two-phase flow and purifies the gas through the action of a porous filter material. It sends the air with low dust content into the room after purification to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room. In addition, in order to obtain a standard air filter, the general ventilation filter is to capture and absorb dust particles of different particle sizes in the air to improve air quality. In addition to absorbing dust, activated carbon filters can also absorb odors. Of course, the general use of ventilation filters is more extensive, such as chemical electronics, paint printing, hotel office buildings, etc.

When selecting an air filter, determine the parameters of the air filter, such as size (including width, height, and depth). If it is a bag air filter, please confirm the number and depth of the bags; the filter efficiency should be determined, such as air primary filter, medium effect filter and high efficiency air filter. There is also the initial resistance parameter. If it is a non-standard filter, please provide filter efficiency and air inlet, resistance and installation dimensions, etc.
