Engineering Overview
PAPTEX Environmental Filter Fabric is an industrial-grade filtration medium engineered for solid-liquid separation in demanding environmental and industrial process applications. The open-weave polyester/polyamide composite structure provides 800–2,000 CFM permeability with precise mesh sizing for targeted particle retention.
With ≥100 kN/m MD tensile strength and chemical resistance across pH 3–11, this fabric handles aggressive process streams in pulp dewatering, effluent treatment, chemical processing, food & beverage filtration, and mining dewatering. The composite construction resists both acidic and alkaline degradation for extended service intervals.
Custom-fabricated to your filter press, rotary drum, belt filter, or tower press specifications. Each fabric includes detailed technical documentation with mesh count, open area percentage, and particle retention curves.
