How often is the Dynamic pass box filter changed?
How often is the Dynamic pass box filter changed?The replacement cycle of the Dynamic pass box filter is affected by the use environment, frequency of use, filter quality, and other factors. The following is the introduction of the replacement time of the initial effect filter and high-efficiency filter in general:Primary filter In a generally clean environment, such as ordinary electronic production workshops, food processing workshops, etc., if the frequency of use is not particularly high, the primary filter is usually replaced every 3-6 months. If the use of environmental dust is large, such as in the production site near construction, or the frequency of use is very high, more than 10 times a day, it may need to be replaced every 1-3 months. High-efficiency filter In a normal clean environment, the service life of the high-efficiency filter is relatively long, and it can generally be used for 1-2 years. For example, in biopharmaceutical workshops, clean operating rooms in hospitals, and other places with high cleanliness requirements but relatively good environments, if the frequency of use is moderate, the filtration efficiency is tested every year, and if the efficiency drops to a certain extent, it is replaced, usually 1.5-2 years replacement is more common. If the Dynamic pass box is used frequently and there are more dust particles in the environment, the blockage of the HEPA filter may be accelerated, and its service life may be shortened to 6-12 months. To ensure the filtering effect and normal operation of the Dynamic pass box, it is recommended to check and maintain the filter regularly and determine the specific replacement time according to the actual situation. |
