Filler wires reduce air permeability and prevent fine material loss, which ensures better filtration performance and a cleaner working environment.
DYOUNG offers spiral meshes with three, four, or five filler wires per spiral ring to adapt to different dewatering and filtration requirements.
Yes, we can supply hydrolysis-resistant polyester meshes and special finishes for chemical resistance and high-temperature stability.
Some loop-and-pin configurations allow section repair, subject to the damage pattern and an approved joining procedure.
They are widely used in papermaking, food processing, pharmaceuticals, mining, coal washing, wastewater treatment, and other industries requiring reliable dewatering and filtration.
