Polyester Filter Press Cloth

Balanced temperature resistance, oxidation resistance and dimensional stability for neutral and weak-acid filtration.

Filter Cloth Series

Polyester Filter Press Cloth

Polyester (PET) filter press cloth is woven multifilament filter medium manufactured from polyester fiber with heat-set treatment. Distinguished from PP, nylon, monofilament cloth and needled filter felt, it delivers balanced performance in temperature resistance, oxidation resistance and dimensional stability. It is widely adopted for solid-liquid separation under neutral and weak acid conditions on plate and frame filter presses.

MaterialWoven polyester (PET) multifilament
Continuous working temperature≤120℃
Transient temperature130℃
pH resistance4~9
Common models729, 750A, 750B, 850
Filtration precision5~45 μm

Product Description
