The guarantee measures of air cleanliness, only qualified air filters are not enough, but also the transportation and installation process does not damage the air filter and the installation is tight. It requires the construction and installation personnel to be well trained, not only to have the knowledge of the installation of the purification system, but also to have more skilled installation skills. Otherwise, it will be difficult to do not damage the air filter. I believe that all the purification colleagues have learned a profound lesson in this respect.

The installation tightness problem mainly depends on the advantages and disadvantages of the installation structure type. The design manual generally recommends that the single air filter be installed in an open type, so that even if leakage occurs, it will not leak to the room. It is easy to obtain the tightness by using the finished air supply outlet. For the tuyere of multiple air filters, liquid tank seal and negative pressure seal are often used in recent years. The tank seal must be tight and the whole frame is on the same level. Negative pressure sealing is to make the outer periphery of the joint between the filter and the static pressure box and the frame in a state of negative pressure, which will not leak to the room even if the leakage is the same as the open installation type. In fact, as long as the installation frame is flat, the end face of the air filter is in uniform contact with the installation frame, and any installation type makes the air filter meet the requirements of installation tightness. It should be not difficult.

Air flow → primary effect purification → humidifying section → heating section → surface cooling section → medium effect purification → fan air supply → pipe → cleaning tuyere → blowing into the room → taking away dust and bacteria and other particles → return air shutter → primary effect purification. The principle of the purification workshop is generally to go through three filter sections: the initial filter, the middle filter, the high efficiency filter or the sub-high efficiency filter. For the common ten thousand level purification workshop, it refers to the clean workshop with ten thousand level air cleanliness.
