    High efficiency air filter air volume change

    Why does the air volume of hpa filter decrease?I believe that many customers have some doubts about this problem in the process of product use. Today we will explain several reasons why the air volume of hpa filter decreases.

    A;First of all, confirm whether the final resistance of the hpa filter (that is, its reported destruction value) has reached the final resistance of the product in the use process. Generally, the final resistance of the hpa filter is 400-600pa.

    Two: the primary effect filter of the front end of the high efficiency filter, whether the intermediate effect filter has also reached the final resistance value, because the former primary effect, the medium effect mainly plays a role in protecting the high efficiency filter, if the front effect of the primary effect of the medium effect filter reaches the reported value of destruction, it also affects the air volume of the high efficiency filter.

    Three;The problem of air conditioning unit is whether the air volume of air conditioning unit has reached the air volume required for the whole purification space in the use process.

    How to accurately know the problem when the air volume of the high efficiency filter decreases? The most correct way is to use professional instruments to detect and speak with data. Some customers of the author make their own judgments based on their own judgment, such as using their hands to perceive the air volume.Well, these are the main factors that reduce the air volume of the high efficiency filter, I hope to help you.
