1. The efficiency of the high-efficiency filter itself is generally detected by the manufacturer of manufacturers, and the filters filtering efficiency report order and certificate of the filter are generally detected by the manufacturer. For pharmaceutical companies, high-efficiency filter leakage refers to the high-efficiency filter and its system installation on-site leakage, mainly to check small pinhles and other damage in the filter material, such as frame sealing, gasket seal, and filtering Driving seams on the instrument frame, etc. The purpose of leakage is to detect the high-efficiency filter and its sealing of the installation of the installation of the frame, and timely discover the defects in the high-efficiency filter itself and the defects in the installation, take the corresponding remedial measures to ensure the cleanliness of the region. 2, the leakage of the DOP / PAO leakage principle The leakage of the high-efficiency filter usually uses the PAO generator to flush up upstream dust in the filter, using the photometer detection filter upstream and downstream gas dissolution
The high efficiency filter is mainly filtered by the end filtration of the filter system of clean room or dust-free workshop, which is an important filter directly related to air cleanliness. The efficient filter leaks as one of the projects detected by clean workshops, the purpose of its detection is to detect the high-efficiency filter and its sealing at the installation framework connection, and timely discover the shortcomings of the high-efficiency filter itself and the installation. Take the corresponding remedial measures to ensure the cleanliness of the area. Then we mainly introduce you to the high-efficiency filter leak detection: 1. The test dust source of sodium flame method is a multi-dispersion phase sodium chloride salt, \"\" is a salt-free burning The brightness of the hydrogen flame. The brine splashes at the agitation of the compressed air, and dried over the fine salt crystal particles and enters the airway, sampled before and after the filter. The color of the hydrogen flame contains the color of the hydrogen flame, the brightness is increased, and the brightness of the flame determines the salt spray concentration of the air, and it is determined to filter
When installing a high-efficiency filter, you should pay attention to the following: 1. When transporting and stored in a high-efficiency filter, it should be put on hold in the direction of the production plant logo. During the transportation process, it should be gently put, prevent severe vibration and collision, so as not to cause human damage. 2. Before the high-efficiency filter is installed, it must be cleaned, wiped, purifying the air conditioning system, if there is a dust removal, and wipe it again, and achieve cleaning requirements.
1. The high-efficiency filter is mainly used in the ultra-clean workbench to capture particulate dust and various suspended solids of 0.3um and below, with a filtration efficiency of 99.99%. Use ultra-fine glass fiber paper as the filter material, offset paper, aluminum film and other materials as the dividing plate, glued with aluminum alloy. The working principle of the ultra-clean workbench: The ultra-clean workbench is equipped with a high-efficiency centrifugal workbench dedicated fan. After filtering by the primary filter and the high-efficiency filter, the clean airflow is sent out in the horizontal or vertical direction in the inner working area of the table to meet The local area's requirements for the production environment are one of the most important purification equipment for improving process conditions and ensuring cleanliness. 2. The ultra-clean workbench is a highly versatile partial clean workbench, which is widely used in electronics, LED, circuit boards, national defense, precision instruments, meters, food, pharmaceuticals and other industries. The outer box of the ultra-clean workbench is made of cold-rolled steel plate with multi-layer electrostatic spraying, and the table is sanded stainless steel plate; both sides of the table are equipped
Regardless of the high-efficiency filter used in any occasion, it must first have a certain understanding of the performance and need to be properly inspected. How is the performance inspection method of high efficiency filter equipment? Come and watch it with us!
