建议终期压损:250Pa。
温度:常温
纸框折叠式过滤器体现整体成套双层、硬模切割、防潮纸板框架的结构特点。滤纸和纸框内所有相连点粘结,提供了一个坚实可靠地结构,以确保过滤器在较差的工作环境下不致变形或者损坏。

空气进出两面的滤纸叠层支撑架是整个框架不可缺少的部分,它进一步增强过滤器的坚固性,有助于保持褶层之间间隙均衡以达到大容尘量,同时使阻力达到较小。

纸框折叠式过滤器适合与高效过滤器组合在一起使用。它可以防止高效过滤器由于灰尘堆积而被过早地更换,从而延长高效过滤器的使用寿命。

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,Fully 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.
