Description
As the perimeter frame of the filter is made of moisture-proof cardboard, there are no any deformations, breakages, or distortions happened consequently. Moreover, the diagonal paper member supporting design of both sides of the frame makes it is possible to hold the filter media more fixedly indeed. In addition, the media V-pleating design makes the free filtration area of the filter being maximized. It not only can provide better filtration efficiency but makes the filter construction being more sturdily and stably so as to ensure a longer life time as well. Besides of that, filter media has been sealed to frame firmly so as to prevent it from air leakage eventually.

The radial wedge creates an air exit area(B) equal to the air entering area(A),which minimizes end losses and reduces pressure drop.
Non-radial wedge pleats have unequal air exit (D) and air entering (C) areas,wihich cause higher resistance and uneven usage of media
