How to improve the service life of high-efficiency air filter Hepa?
How to improve the service life of high-efficiency air filter Hepa?For a running clean room, the value of the terminal high-efficiency filter is not high. The total value may be less than the user's output value for a few hours. However, the risks and indirect costs of replacing the terminal high-efficiency filter will be very high. When replacing the filter, To stop production, only the owner can calculate the loss caused by the stoppage of production. This loss is higher than the cost of spare parts for the filter. So how do we increase the service life of the high-efficiency air filter Hepa?To extend the service life of the HEPA air filter, the fundamental way is to block dust in the pre-filter. Replacing the pre-filter generally does not require shutdown or debugging, so experienced owners will spend their attention and money on the pre-filter. and protection-level intermediate filters. For 10K-level and 100K-level clean workshops, G4 is used for pre-filtration, and the F8 filter (colorimetric method 95%) can be used for the intermediate level. In this way, the service life of the terminal high-efficiency filter can generally reach 5 years. F8 filter is a common pre-filter in non-uniform flow clean rooms. In some cases, the service life of high-efficiency air filter hepa is not due to resistance considerations, but to extend the service life of high-efficiency filters, the fundamental way is to Dust block the pre-filter. In some cases, the service life of the high-efficiency filter is not based on resistance considerations, but on other factors. If the workshop air conditioning is not a fresh air system, the glass fiber filter paper in the high-efficiency filter will be corroded by the return air. For safety, the high-efficiency filter must be replaced regularly. Some large pharmaceutical factories must replace the high-efficiency filter every year after the rainy season. It is to prevent any possible mold contamination on the filter. Some biological laboratories and laboratories dealing with dangerous goods will require the use of new high-efficiency filters for reliability before starting a new research topic. |
