Do You Know The Replacement Time Period Of The Air Filter?

For frequently used air filtration equipment, there is a certain time limit for use, and the air filter is the core component that needs to be replaced frequently. When using it, we should understand the relevant knowledge of the device so that we can use it better.

First, some experienced professionals summarize some dos and don'ts for air filter replacement. It is important that when the resistance of the device reaches 2-3 times the initial resistance, it should be stopped immediately and replaced with new air. filter. Check the color of the filter on the leeward side of the equipment. If the color of the filter material turns black, it should be replaced in time; the filter material can be touched by hand on the wind side of the equipment. If more dust is felt accumulated, it should also be replaced; record each time the air filter is replaced If the pressure difference between the clean room and the adjacent room is not significantly different, the resistance of the equipment may be too large and should be replaced; if the cleanliness of the clean room does not meet the original requirements, perhaps Yes, the negative pressure should be replaced as needed.

Second, if it is an air filter used on the purification workbench, the replacement time can be selected through the pressure difference gauge in the purification workbench; if it is an FFU fan filter unit, the replacement cycle is controlled by a PLC system. Hint solved the problem.

Third, no matter what kind of air filter is installed in the environment, we need to record its operating time in detail so that it becomes the basis for our replacement.

Fourth, if under normal working conditions, the service life of a high-efficiency air filter is generally more than one year; if it is an air filter with better protection, the service life can last for more than two years, of course, it depends on the equipment. The quality is good or bad.
