空Gas filter is a common purification equipment in operation room. However, we seldom pay attention to the matters needing attention in the maintenance of filters. So what are the maintenance methods of purifier filter? This needs to be judged according to the type of filter.

Purification filter
1. The core part of the purification filter is the filter core. The filter element is composed of a filter frame and a wire mesh. The wire mesh is suitable for damaged parts and needs special protection.
2. When the filter is working for a period of time, some impurities are deposited in its core. At this time, the pressure drop increases and the flow rate decreases. It is necessary to clean up the impurities in the filter core in time to ensure the normal use of the filter.
3. When cleaning impurities, special attention should be paid to the fact that stainless steel wire mesh on the filter core can not be deformed or damaged. Otherwise, the purity of filtered media can not meet the design requirements, and the compressor, pump, instrument and other equipment will be damaged.
4. If the wire mesh is found to be deformed or damaged, it should be replaced immediately.
Two. Operation room purify precision filter.
1. The core part of the precision filter is the filter element, which is composed of special materials and is suitable for damage and needs special protection.
2. When the precision filter works for a certain period of time, the filter element will block a certain amount of impurities, when the pressure drop increases, the flow rate will decrease, it is necessary to remove impurities in the filter in time, and at the same time, the filter element should be cleaned.
3. When removing impurities, special attention should be paid to the precision filter element, which should not be deformed or damaged. Otherwise, the purity of filtered media can not meet the design requirements.
4. Some precise filter elements used in operation room should not be used repeatedly, such as bag filter element and polypropylene filter element.
5. If the filter element is found to be deformed or damaged, it should be replaced immediately.
The above is some maintenance methods that Ed purify to summarize for everyone. If you need to know more about purification, please pay attention to the public address: Aide-188 (Ed purified oxygen supply).
