In the pharmaceutical industry, high -efficiency filters (HEPA) are used for the processing and filter of the processing and filtering of space air. Sterile production requires compulsory use of high -efficiency filters, and the production of solid and semi -solid dosage forms is sometimes used. H13 to H14 (DIN1822) is two types of high -efficiency filters, with an interception rate of 99.995%. But how long does it take to change?
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.
High-efficiency air filters have been widely used in clean workshops in medical, electronics, fine manufacture, biomedicine and other industries. High efficiency and ultra-efficient filters are used in the end of the clean room. The seal of the high-efficiency air filter is directly related to the cleanliness of clean space. What method can be used to improve the sealing effect of the high-efficiency filter? The following is a sealing effect of Shandong Xinli to improve the sealing effect of high-efficiency air filters: 1. By using a negative pressure leakage seal method, the pollution air of the positive pressure space is transmitted to the work area. Pressure space to ensure that the work area is not polluted. 2, liquid tank sealing method, this method is in the groove frame, injecting the sealing liquid, insert the mouth of the high-efficiency filter into the sealing liquid, so that the air passage on both sides is blocked, and the sealing purpose is achieved. This sealing method is reliable, and the filter is convenient, usually applied to 100, 10 and higher.
Ventilation of the dust-free work is available in two different methods: traditional airflow system and one-way airflow system. In the conventional airflow system generally used, the air blowing is done by one or more high-efficiency filters in different locations in the room, and the one-way stream system is air blowing through the high-efficiency filter full of the entire ceiling or the entire wall. Dust-free workshop high efficiency filter should be based on the construction area, air cleanliness level in front of the construction area before the installation replacement cycle
The wind shower room is an employee to enter the clean room or a dust-free workshop essential buffer purification device, which can reduce the pollution problem brought by employees into and out of clean room. The wind turbulent channel is a versatile partial purification device installed between clean room and non-cleaning room. The main applications of the wind shower room are: laboratory, biomedicine, food processing, electronic, circuit board, photoelectric, LED, optical, instrument, aerospace, etc. The air shower is filtered through the initial filter. After the high pressure fan enters the static pressure box, the clean air flow after the high-efficiency filter is filtered, and the rotary nozzle is injected from the various directions to enter the cleansing room, thereby effective and rapid Filter dust particles. The cleared dust particles were recycled to the wind shower region after filtration, and the high-efficiency filter was filtered. Due to the different characteristics of the clean room, the selection of high-efficiency filters first follow the level of clean room, sterility, temperature and humidity,
