High Efficiency FilterWhat are the structural requirements? How to extend the service life of the filter?

High Efficiency FilterThe types of HEPA filters include high efficiency air filter with partition and high efficiency air filter without partition. According to the structure, they are mainly divided into: H13 high-efficiency filter with partition, H14 high-efficiency filter without partition, and combined high-efficiency filter.

Separatorless high-efficiency filters include combined high-efficiency filters, HV-type combined high-efficiency filters, liquid tank separatorless high-efficiency filters, ultra-high-efficiency filters, sub-high-efficiency filters, ultra-low-impedance separatorless high-efficiency filters, knife-rack separatorless high-efficiency filters and so on. Separatorless plate mainly adopts thermosol as the separator of filter element, which is convenient for mechanized production. In addition, it has the advantages of small volume, light weight, easy installation, stable efficiency and uniform wind speed, and the large quantity of filters required for clean plants are mostly made of non-separator structure.

Separator high-efficiency filters include separator high-efficiency filters, high-temperature-resistant high-efficiency filters, high humidity-resistant high-efficiency filters and so on. Separator high-efficiency filter mostly adopts aluminum foil, high-quality kraft paper to make folded cartridge separator, hot roll forming or offset paper as a separator, so as to form an air channel. According to Yifan's many years of experience, when the temperature and humidity change, the paper partition may have larger particles emitted, thus causing the cleanliness test of the clean plant to be unqualified, so it is recommended that new and old customers use aluminum partition high-efficiency air filters.

High-efficiency air filter media are mainly chemical fiber nonwoven fabrics, glass fibers, some manufacturers have a mixture of cotton fiber and chemical fiber filter media, metal mesh, etc. Currently, some foreign manufacturers use electrostatically charged polytetrafluoroethylene fibers (electret) to manufacture high-efficiency filters, commonly known as PTFE.

Main performance parameters of high efficiency filter structure:

I. Air volume: 500-3000m3 /h

Second, the initial resistance: ≤ 220Pa

Dust filtering efficiency: ≥99.99% (sodium flame method)

How to Extend the Life of a Dense Pleated Filter

Dense pleated filter is also one of the air filters, air filters are air filtration devices, most of which are used in clean workshops, clean factories, clean operating rooms, laboratories and clean rooms, or used for dust prevention of electronic machinery and communication equipment, etc. There are five types of filters: primary filters, intermediate filters, high and middle filters, and sub-high efficiency filters and high-efficiency filters. There are five types of filters: primary filter, medium efficiency filter, high efficiency filter, sub-efficiency filter and high-efficiency filter. Each type has different standards and efficiency, and the pleated filter is one of the most frequently used ones.

Dense pleated filter is mainly used in central air conditioning and industrial ventilation systems, using imported glass fiber filter media, low resistance, large filtration area, and space-saving, easy to install, and can be interchanged with the ordinary bag filter, its outer frame is made of aluminum alloy or environmentally friendly materials, such as this material can be incinerated and also meet the requirements of environmental protection, it is important that the service life of the dense pleated filter is more permanent.

Then to make the dense pleated filter last long, you need to install and use it correctly.

Mastering the correct installation method is a key prerequisite to ensure the quality of the equipment, in fact, the installation process of the filter is not difficult, but in the installation process the relevant professionals must pay special attention to ensure that the installation of the environment cleanliness, if the conditions allow it, it must be the filter for air blowing, in order to achieve the purpose of cleaning, followed by cleaning up the purification workshop, the installation of the time to try to Configuration of an ultra-clean filter bag vacuum equipment, so that more insurance.

Filter may be installed in the location of the anger, if the filter is installed in the ceiling inside, then the ceiling inside should also be cleaned, because this will ensure that the efficiency of the filter in the operation of the filter, and of course, only after constant repeated cleaning, to achieve the filter filter effect.

Ensure that the use of dense pleated filter effect of correct installation is one aspect, but also pay attention to the use of the process of operation, maintenance and maintenance of the way and method, because only in this way to ensure that the service life of the filter in the normal operation of the premise, to play the filter of the overall value of the larger, to improve the end of the use of the efficiency and quality, so in the use of the previous to read the use of the instructions, and to find out the right way to use the process, everything should be carried out according to the relevant standards. So before use, read the instructions carefully and find out the correct use process, and everything should be carried out according to the relevant standards.

It can be seen that if you want to ensure the use of the effect and service life of the pleated filter, not only the correct installation method, but also the correct standardized operation, maintenance and repair methods.
