CFM:**0
They have the characteristics of good water permeability, air
permeability and non-revealed sludge, acid-resisting,
alkali-resisting, heat resistance (**0℃) .
Because of their designing structure, the sludge can be peeled off
easily after pigeonhole filter, so the screen are easily cleaned
and have a long working time. Therefore they are designed specially
for sludge dehydration.
