Supply air cleanliness protection measures, only qualified air filter is not enough, but also the transportation installation process does not damage the air filter and the installation is tight. The construction and installation personnel are required to be well trained, both to have the knowledge of the installation and purification system, and to have more skilled installation skills, otherwise it will be difficult to do not damage the air filter, I believe that in this respect all purification colleagues are profound lessons.

Installation tightness problem, mainly depends on the advantages and disadvantages of the installation structure type, design manual generally recommended for a single air filter installed type, so that even if leakage, will not leak into the room; Using finished air outlet, the tightness is also relatively easy to get. For the tuyere of many air filters, liquid tank seal and negative pressure seal are often used in recent years. Liquid tank sealing must be tight liquid tank joints and the overall frame are on the same level. The negative pressure seal is to make the filter and the plenum and the frame joint around the negative pressure state, and the same as the open type even if the leakage will not leak into the room. In fact, as long as the installation frame is flat and the end face of the air filter is in even contact with the installation frame, it should be easy for any installation type to make the air filter meet the installation tightness requirements.

Air flow → initial effect purification → humidification section → heating section → surface cold section → medium effect purification → fan air supply → pipeline → purification tuyce → blowing into the room → taking away dust, bacteria and other particles → return air shutter → initial effect purification. The principle of purification workshop is generally to go through three filtration sections: initial filtration, medium filtration, high efficiency filtration or sub-high efficiency filtration. To the common ten thousand grade purification workshop, refers to the air cleanliness of ten thousand grade clean workshop.
