紙框折疊式過(guò)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(diǎn)。濾紙和紙框內(nèi)所有相連點(diǎn)粘結(jié)，提供了一個(gè)堅(jiān)實(shí)可靠地結(jié)構(gòu)，以確保過(guò)濾器在較差的工作環(huán)境下不致變形或者損壞。

空氣進(jìn)出兩面的濾紙疊層支撐架是整個(gè)框架不可缺少的部分，它進(jìn)一步增強(qiáng)過(guò)濾器的堅(jiān)固性，有助于保持褶層之間間隙均衡以達(dá)到大容塵量，同時(shí)使阻力達(dá)到較小。

紙框折疊式過(guò)濾器適合與高效過(guò)濾器組合在一起使用。它可以防止高效過(guò)濾器由于灰塵堆積而被過(guò)早地更換，從而延長(zhǎng)高效過(guò)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.
