we meet the problem how can we improve the ventilation and
smoothness, reduce adhesive powder, and low the resistance to get
the better filter. Luckily, we have developed needling carpet with
resinifiction smooth surface. The ventilation is above 50% for
filing than common one . and the surface is much more smooth than
the press polish. Now we got the order to the ventilation from our
laboratory according to the precision: singeing material> easy
cleaning filter material> common press polish filter material.
According to the moving resistance:
cleaning filter material <singeing filter material< common
press polish material filter.
ventilation and low resistance are our goal. Now you are provided
another choose: needling
filter cloth with easy cleaning surface
