Mistaken idea of pleat number of a / C filter element

Most car owners may intuitively see the wrinkles of the A / C element at the moment of opening the new a / C element, and may think that the more wrinkles, the better the filtering performance of the A / C element. In fact, there are two main factors that determine the performance of the A / C filter element. The first is the filtering performance of the filter material of the A / C element. For products with the same filtering area and different filtering materials, their filtering efficiency, ash holding capacity, adsorption capacity, antibacterial and anti allergic capacity will be very different. The second is to increase the number of pleats of the A / C element within a reasonable range, which can improve the filtering performance. However, if the number of pleats is too large, the air resistance of the A / C element will increase, resulting in insufficient air output of the A / C.

 

Gram weight of activated carbon

I believe that many vehicle owners have a deep misunderstanding about the activated carbon air-conditioning filter element. They feel that the heavier the activated carbon air-conditioning filter element, the more activated carbon it contains inside, and the better the filtering performance of the air-conditioning filter element. In fact, it is not completely correct. The adsorption capacity of activated carbon depends on its internal pore structure, of which the internal micropores play a decisive role, that is, the pores with a pore size less than two nanometers. The more micropores, the larger the surface area, the higher the capacity and the stronger the adsorption capacity. Compared with the general wood charcoal and coal activated carbon, coconut shell activated carbon after activation has stronger performance. The low-quality and cheap activated carbon air-conditioning filter element uses activated carbon of ordinary materials, and has not been activated and perforated. Even if more activated carbon is added to the air-conditioning filter element, it will not have adsorption effect, but will increase the resistance of the air-conditioning filter element and reduce the intake air.
