Judging the best of the F5 medium-efficiency bag air filter can be judged from the following aspects:
1. Observe the appearance. The housing of a high-quality filter should be smooth, free of creases or bumps, the welds should be intact, the outer frame should be smooth to the touch, and the sealing surface should be free of impurities and dust. If the product has the above problems or the production process is rough, it is not recommended to buy and use. At the same time, it is also important to check whether the air inlet roller is smooth. If there is an abnormal sound or other abnormal situation, it means that the quality of the product may not be good. In addition, the detection device of the air outlet should also be checked for wear and aging, which will also affect the final use effect.
2. Checking the internal structure is also an important criterion to measure product quality, the user can open the machine with the naked eye to observe, a good bag should be dense fiber is not easy to fall off for the best choiceLow-quality filters tend to be wrinkled and uneven; Metal parts should be bright and clean without paint; The adhesive strip should be thick and soft, and there should be no cracking and curling edges.
3. It is the performance test time inspection that will never go out of style!You can buy a few and come back to buy a few more manufacturers at one time, shop around, and consider and compare according to the actual use environment! From the perspective of noise level, the technical level of the manufacturer is also relatively good; Looking at the cumulative replacement of the cycle, the comprehensive cost is the real benefit!
In short, through the above steps, you can roughly determine the advantages and disadvantages of the device. It should be noted that these are only general suggestions and methods for your reference, and the specific operation should be flexibly dealt with in combination with the actual situation, so as to achieve the unity of knowledge and action, in order to achieve twice the result with half the effort.
