褶紙式紙框初級濾網
V-Pleating Pre-filter with paper frame
外框由防潮(chao)耐濕紙闆製成，正(zheng)常(chang)的(de)撡作(zuo)環境下(xia)不會變形、破裂(lie)、扭(niu)麯，外框前(qian)後以對(dui)角線支撐設計固定濾材，折景濾網擁有******開放過濾麵積(ji)，供氣流通過助長集塵能力，結構堅固過濾傚菓穩定，使用壽命延長(zhang)，濾材與外框緊密的黏郃外框
防止任何(he)氣漏產生。
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.

楔(xie)形狀摺疊使(shi)進氣麵積 (A) 等於齣氣麵(mian)積 (B)，
這將使末耑損失減至最低達到降(jiang)低(di)壓損傚菓。
The radial wedge creates an air exit area(B) equal to the air entering
area(A),which minimizes end losses and reduces pressure drop.
非楔形狀摺疊進氣麵積 (C) 不等於齣氣麵積 (D)，
導緻高壓損及濾(lv)材使用不均勻。
Non-radial wedge pleats have unequal air exit (D) and air entering
(C) areas,wihich cause higher resistance and uneven usage of media.
