high efficiency filterLeakage is one of the items of clean workshop inspection, which has received more and more attention since the implementation of the 2010 version of GMP. It can be seen that the daily maintenance of high-efficiency filters is a very important issue. So, how to maintain high efficiency filter?
First of all, what ishigh efficiency filterWhat?
The high-efficiency filter is mainly used to capture particles below 0.3um dust and various suspended solids. The partition board was made of filter paper, film, aluminum film and other materials, and the superfine glass fiber paper was made of high-efficiency filter baffle. Each unit has the characteristics of high filtration efficiency, low resistance and more dust.
Second, how to maintain efficient filters?
1. Do not tear or open the packaging envelope or packaging film by hand before installation. The standard filter should be in the direction indicated in the high-efficiency filter box. In the process of transportation, in order to avoid intense vibration and collision, should be gently lifted and light.
2. Its transportation and storage should be reserved according to the direction of the production plant mark. In the transport process, in order to prevent intense vibration and collision, to gently put, forced loading and unloading crossing.
3. The installation direction must be correct. When the corrugated combination filter is installed vertically, the corrugated plate must be perpendicular to the ground. The filter is a connection between the vertical and the frame. It is strictly forbidden to leak, deform, damage, adhesive, etc. After installation, the inner wall should be clean and free of dust, oil, corrosion, debris, etc.
4. Installationhigh efficiency filterBefore, the clean room must be fully cleaned and cleaned. After the air conditioning system is full of dust, it must be cleaned and cleaned again. Cleaning requirements must be met. If high efficiency filters are installed in the technical mezzanine or ceiling, they must be thoroughly cleaned and cleaned in the technical floor or ceiling.
5. If the resistance value of the filter is greater than 450Pa, or the outflow airflow velocity is the smallest, the airflow velocity will not increase even after replacing the coarse effect and medium effect filters. Or, if an irreparable leak occurs on the surface of the high-efficiency filter, it should be replaced with a new high-efficiency filter.
The above content is the daily maintenance technology of the high-efficiency filter introduced by the editor today. Of course, if there is no such condition, it can be replaced once a year or two according to the use environmental conditions.
