Speaking of air filtration The reaction may be a device that filters the air. This equipment is found in air purification plants or clean laboratories. But with the development of technology, there are more and more filters of this type, and high-efficiency air filters are one of them. How much resistance can this device withstand during use? How to replace equipment after it is scrapped? Let’s take a look at the introduction below.
1. Introduction to the resistance that high-efficiency air filters can withstand during use：
Different types of filters have different filtering standards and will also be used in different filtering fields. The equipment can filter substances with a particle size not less than0.3 micron and an initial resistance not greater than 220 Pa. This equipment is often used in air conditioning purification systems and is mainly used as a terminal filter. Especially in some cleaning projects where the cleanliness requirement is 0.3 micron, there are professional regulations that such projects must use this terminal equipment.
2 , high-efficiency air filter Replacement method ：
The main condition for replacing the high-efficiency air filter is that the equipment itself has been scrapped, which requires everyone to judge whether the equipment is genuine scrapped. When determining scrapping, the use environment needs to be checked. For example, the dust suspended in the room changes significantly, and the surface of the air outlet is damaged and dirty, which means that the equipment needs to be replaced. When replacing, it is necessary to remove the diffusion plate of the scrapped equipment and loosen the fixings of the equipment. After disassembling the equipment, the plenum, fixtures and panels must be inspected for corrosion or damage. If corrosion is found, the corrosion state needs to be changed and painted. After completing the above work, new equipment needs to be used according to specifications and quantities.
When installing new equipment, you need to check whether the outer packaging of the equipment is damaged, whether the documents are complete, whether the outer frame is durable, and whether the filter paper is damaged. After removing the outer packaging, the device should be placed in a clean and dry place. The inner packaging must be intact before installation.
The above is the relevant introduction to the replacement of high-efficiency filters. At the same time, we would like to remind you that when replacing equipment, clean the static pressure box first, then open the inner packaging of the equipment, stick the sealing strip on the air inlet side of the equipment, and then place the equipment into the static pressure box and keep it stable. Note handling with care.
