The high-efficiency filter with clapboard needs to be replaced after being used for a long time. Timely replacement is better for most of the production using dust-free workshops. In fact, the value of the end filter is not high for the entire production workshop. It may be less than a few hours of production value, but the risk and indirect costs of replacing the filter will be relatively high, which is why most customers generally require replacement and installation during holidays or even during the Spring Festival after purchasing high-efficiency filters. The reason for replacing the installation during the period.
1. Because the replacement of the high-efficiency filter will stop production, and the loss caused by the stoppage of production can only be calculated by the business owner. This loss must be higher than the cost of spare parts for the high-efficiency filter.
2. Replacing high-efficiency filters is a very serious operation. Everything in the clean room may be expensive, and the loss of destroying one of the components may be higher than the purchase cost of all filters. After replacing the high-efficiency filter, it needs to be inspected by professionals, and sometimes the air conditioning system needs to be debugged, and it needs to go through a period of trial operation. These times are extremely long for enterprises.
3. Testing, commissioning, trial operation, the three costs added together may be comparable to the price of high-efficiency filters with partitions. Smart owners always hope to prolong the service life of the high efficiency filter as much as possible, not to save the cost of the high efficiency filter, but to avoid the trouble caused by replacing the filter and various troubles of the product.
4. In some occasions, the regulation on the service life of high-efficiency filters is not based on the consideration of resistance, but other factors. If there are chemical substances such as hydrofluoric acid in the dust-free workshop, and the workshop air conditioner is not a fresh air system, the glass fiber filter paper in the high-efficiency filter will be corroded by the return air, and the high-efficiency filter must be replaced regularly.
In some large pharmaceutical factories, the high-efficiency filters with clapboards are replaced every year after the rainy season in order to avoid any possible mold contamination on the filters. Some biological laboratories and laboratories dealing with dangerous goods will require the use of new high-efficiency filters for reliability before launching a new and important subject.
