DFX-PES™ Polyester Dust Filter Bags

DFX-PES™ Polyester Dust Filter Bags provide a durable and economical solution for standard industrial dust collection. Manufactured from polyester needlefelt, these bags are designed for continuous service up to 135 °C, with short-term temperature peaks reaching 150 °C. They deliver stable performance in dry, neutral environments, supporting efficient particulate capture and reliable airflow control.

DFX-PES™ bags are a practical choice for a wide range of industrial processes requiring consistent dust filtration without the higher cost of specialised high-temperature materials. Typical applications include general manufacturing, woodworking, food processing (dry zones), plastics, and other ambient-temperature dust collection systems.

Technical Specifications
  • Material: Polyester needlefelt, basis weight 500–550 g/m²
  • Operating Temperature: Continuous up to 135 °C; peaks up to 150 °C
  • Micron Ratings: Typically 5–50 μm, depending on finish and application

  • Compliance: OEM-equivalent constructions; food-contact compliant variants available on request (FDA 21 CFR; EU 1935/2004 & 10/2011)
  • Add-Ons: Wear pads, anti-collapse rings, top-load guides, spark-resistant cuffs
  • Pleated Option: Available for space-constrained systems; increases surface area and extends service life
Applications
  • Woodworking & Furniture Manufacturing – efficient capture of sawdust, sanding dust, and fine wood particulates
  • Grain Handling & Milling – dust control in silos, conveying, and feed processing (non-explosive, dry conditions)
  • Cement Grinding & Minerals Processing – capture of abrasive fine dust at moderate temperatures
  • Steel Fabrication & Metalworking – collection of welding fumes, grinding, and cutting dust.
  • General Industrial Dust Collection – found in manufacturing plants, packaging lines, and
    material handling systems
