Types of operating room air filters and their service life
Types of operating room air filters and their service lifeOperating theatres all need clean rooms, the main function of clean rooms for indoor pollution control, without clean rooms, pollution-sensitive parts can not be mass-produced, due to the different characteristics of clean rooms, the choice of operating room air filters should first be determined by the level of clean rooms, the degree of sterility, temperature and humidity, the degree of fire resistance, anti-corrosion and other different requirements, to meet the use of highly clean environment requirementsOperating room air filters are generally divided into several categories: partitioned, partitionless, V-shaped, high-temperature resistant, mainly used to filter air-suspended particles below 0.3um, as the end filtration of various filtration systems, high temperature, and high humidity conditions, it is appropriate to use metal partitions and metal frame filters; corrosion-resistant requirements should be used plastic partitions and plastic frame filters; fire-resistant requirements, all the materials of the filter should be Non-combustible, etc. Each high-efficiency filter is tested one by one before leaving the factory to ensure the performance indicators of high-efficiency filters. The service life of the operating room air filter is generally more than one year, the most reasonable basis: use the particle counter to test whether the cleanliness of the clean room is up to standard, and if more than should be replaced, before the high-efficiency filter there are generally primary and intermediate filters, some primary filters are washable, if not changed for a long time, the middle effect will affect the service life of high efficiency. If there is a differential pressure table installed at the end, according to the differential pressure table, you can know that the filter should be replaced, high efficiency 1.5 years or so to replace, if the middle effect of good protection, and high efficiency of the effective cycle will be longer, the specific use cycle according to the use of different environments cycle is not the same. |
