Features of Polyimide Dust filter bag:
1. It is not necessary to reconstruct the box and increase the filter area of system by 50-150% as
needed;
2.The effective bag spacing is greatly increased, and the cleaning efficiency is greatly improved;
3.Extended bag life.
P84 dust filter bag has three main advantages:
1.High temperature resistance
the Working temperature is 260 , and It has great ability to deal with accidences.
2.Excellent chemical resistance
Decades of years of imcineration house practice has proved the value of P84 bags,especially for
acid gas abd alkali dust filtration and collection.
3. Low converse washing pressure and great dust cleaning ability.
P84 filber is small dtex, which enlarge the advantage, the erose fiber cross section ensures the
largest fiber surface area and provides large number of small openings. because of this, the dust
will be mainlu retained on the surface of felt, will be easily cleaned up. The pressure drop will be
veru small.
