紙框折疊式過濾器體現(xiàn)整體成套雙層、硬模切割、防潮紙板框架的結(jié)構(gòu)特點。濾紙和紙框內(nèi)所有相連點粘結(jié)，提供了一個堅實可靠地結(jié)構(gòu)，以確保過濾器在較差的工作環(huán)境下不致變形或者損壞。

空氣進出兩面的濾紙疊層支撐架是整個框架不可缺少的部分，它進一步增強過濾器的堅固性，有助于保持褶層之間間隙均衡以達到大容塵量，同時使阻力達到較小。

紙框折疊式過濾器適合與高效過濾器組合在一起使用。它可以防止高效過濾器由于灰塵堆積而被過早地更換，從而延長高效過濾器的使用壽命。

Premium performance and construction
High loft media increases dust holding capacity
Contoured pleat Design
Wide selection range

Frame:Rigid water resistant cardboard.
Media:Mixture of cotton and synthetic fibre，F(xiàn)ully supported media boned onto a wire support grid Robust construction
Efficiency:(EN779:2002 filter class)G4
(ASHRAE 52.2:2007 filter class)MERV8.
Recommended final pressure drop:250Pa.
Temperature:70?C maximum in continuous service.

Paper folded filters are constructed totally unitized.double wall ,die-cut,moisture resistant beverage board frame.The media is bonded inside the frame at all points of contact,providing a sturdy,reliable construction that does not rack or deteriorate under difficult operating conditions.

The media pack support retainers,which are an integral part of the frame at both the air entering and leaving sides ,increase filter rigidity .it helps maintain equidistant spacing between pleats for maximum dust holding capacity while minimizing resistance.

Paper folded filters are ideal for use as prefilter in combination with high efficiency filters.It helps extend the life of the higher efficiency filter from premature dust loading and replacement.
