Ultrasonic Composite Filter MaterialUltrasonic press-point composite filter-material is compounded of
polypropylene super-fine fiber nonwonvens and polyester nonwonvens
by ultrasonic press-point. Compared with other products at the
condition of reaching the same efficiency, the resisitance of this
filter material decreases by 20 percent. Simultaneously, it owns
the advantage of great dust capacity, high intensity, and extending
the life-span of filter, so that this product is an ideal filter
material used in air filters.
