Why should be righthigh efficiency filterWith the development of economy and the improvement of scientific research technology, clean room has been widely used in daily life, and high efficiency filter as one of the important equipment of clean room, widely used in electronics, chemical, pharmaceutical, food, medical, machinery, biological engineering and other industries. The airflow in the clean room is mainly vertical unidirectional flow and horizontal unidirectional flow. The airflow speed of vertical unidirectional flow is between 0.25 m/s and 0.5 m/s, which can produce 100, 10, 1 or higher clean airflow. The airflow speed of horizontal unidirectional flow is between 0.3 m/s and 0.5 m/s, which can produce 100 clean airflow.
Clean room four important technical elements:
(1) The inlet air must go through three stages of coarse filtration, medium filtration and high-efficiency filtration, and must be set at the end of the system.high efficiency filter;
(2) When designing a clean room, it is necessary to design sufficient purification air supply;
(3) establishment and maintenance of positive and negative pressure in clean room;
(4) reasonable air flow organization under high efficiency filter.
Filter leak detection is an essential quality control link in the finished product inspection process of high efficiency filter manufacturers.high efficiency filterThe leak detection platform provides standard detection methods for filter manufacturers for special elements of leak detection. During the leak detection process of the high efficiency filter, when a suspected leak is detected, the instrument will give an alarm if the leak point value is exceeded, indicating that there may be a leak here, so that this position can be measured in a targeted manner or scanned repeatedly. If the scan value does not exceed the limit, it means there is no leakage and you can pass. If the exceedance continues during the scan, there is a leak and it will not pass. The result of scanning leak detection can be printed on the scanning leak detector in time to determine whether the tested high-efficiency filter is qualified.
