ar101
  The tadial wedge pleats create an air exit area(B) equals to the air
entering area(A), which minimizes end losses and reduces pressure drop.
楔形狀摺疊使進氣面積(A)等於出氣面積(B),這將使末端損失減至最低達到降低壓損效果。

  Non-radial wedge pleats have unequal air exit (D) and air entering (C)
areas, wihich cause higher resistance and uneven usage of media.
非楔形狀摺疊進氣面積(C)不等於出氣面積(D),導致高壓損及濾材使用不均勻。

Features:
W-PRE radial wedge pleat is with the greatest media area exposed to the air flow which can contribute filter’s dust collection capacity.

W-Pre Disposable Pleated Air Filters are available in a wide range of sizes; and with slight or without any system modification, is able to fit most commercial and industrial installations.
Only need to use gaskets and fasteners to adapt W-PRE filter to existing filter bands.

Efficiency:
Per ASHRAE 52.1-1992 standard, the filters have an average atmospheric dust spot efficiency range 30-35% (in NBS Test Method; per ASHRAE 52.2, the efficiency is MERV8) and an average arrestance of 90-94% (in AFI test method).

Media:
W-PRE filter media is a special blend of nonwoven cotton and synthetic fibers offering high dust-holding capacity and high efficiency.

Media Support Grid:
Expanded painted metal provides a flat, stable surface that allows 100% media to metal adhesion. This eliminates media damage caused by overlapping wire grids that cannot be 100% attached. Expanded painted metals give a better corrosion resistance than others.

Outer Frame:
Outer frame can be also a wide range of metal selection which is including of Paper, Galvanized Steel, Aluminum and Stainless Steel. The paper frame is constructed of high wet strength, moisture-resistant beverage board. Two mating die-cut boxes are bonded together, forming a double wall around the entire filter. Diagonal supports are designed for maximum open area while providing excellent structural stability in heavy dirt loading.

特色:楔形褶疊具最大的過濾面積,供氣流通過助長集塵能力,其於高性能及長時間之需
    求中被廣泛接受,也適用於可變風量系統,使用扣夾,即可安裝於箱體裡。

效率:依ASHRAE 52.1-1992標準法測定,此種濾 網具比色法效率30~35%,比重法效率
    90~94%。

濾材:濾材是由不織布棉和合成纖維經特殊混紡製成,提供高集塵量、高效率。平坦的擴
    張金屬網,濾材100%和鐵網貼合,披覆處理之擴張金屬網抗蝕性優於其他鐵網。

外框:框材可選用紙框、鍍鋅鐵框、鋁框或不袗框。高耐濕紙板外框,上下兩張厚紙板
    貼合形成一雙壁邊框,其對角支撐設計於高集塵量下,結構堅固並擁有最大開放面
    積。
