HL500 Series Polyester Needle Punched Filter Fabric Industrial Dust Collector Filter Bag Material

一,Product Overview

The HL500 series includes two variants: HL500Ⅰ Ordinary Polyester Needle Punched Filter Material and HL500Ⅱ Easy‑Cleaning Polyester Filter Material, widely manufactured into filter bags for industrial dust removal systems. Both adopt polyester filament base fabric as raw material, processed with professional post‑finishing techniques to deliver stable dust interception performance for baghouse dust collectors.

二,Craftsmanship & Core Advantages

HL500Ⅰ Standard Grade

Raw material: 2D polyester fibers needle‑punched on polyester filament base fabric

Post‑treatment: singeing, calendering and setting

Performance highlights: high porosity, outstanding wear resistance, folding endurance and air permeability; ideal universal dust‑removal filtration medium for conventional industrial scenarios.

HL500Ⅱ Easy‑Cleaning Grade

Special shaping & finishing process applied to polyester filter fabric

Surface feature: smooth and flat surface to reduce dust adhesion effectively

Cleaning merit: captured dust falls off easily during collector pulse blowback; excellent ash‑discharge effect, prominently lifting overall dust removal efficiency.
