NOMEX aramid fiber felt dust filter bag for bag filter
Product Application---Industrial products
With the increasingly severe situation of industry environmental
protection, industrial enterprises will gradually change the
electric dust removal to bag filter. And traditional filter bag’s
dust removal principle is when the air with dust go through the
filter bag, which rely on to the surface of the filter medium to
establish a layer of dust (powder) to effectively filter and only
make the gas go through to achieve the purpose of dust removal. The
disadvantage is long establishment time of effective filtration,
high resistance, low efficiency, incomplete interception, the large
loss, the high anti - blow pressure for the filter box, frequent
cleaning, high energy consumption and short service life, in
addition, equipment covers an large area.
4M-ePTFE membrane bag filter makes dust not to penetrate into the
filter medium, just surface filtration. Regardless of the thickness
of dust, all of them deposit onto the surface of the filter medium.
The membrane aperture itself intercept dust, no first filtration
period, and the beginning is the effective filtration, nearly 100
percent of the time is in filtering.
4M-ePTFE membrane bag filter is with excellent performance in high
filtration efficiency, low voltage, high throughput, easy cleaning,
long service life and other advantages.
