DFX-PE™ Polyester Dust Filter Bags

• Material: Polyester needlefelt, basis weight 500–550 g/m²
• Operating Temperature: Continuous service up to 135 °C; short term peaks up to 150 °C
• µm Ratings: Typically 5–50 µm, depending on media finish, dust loading, and application conditions
• Finish Options: Singed, glazed, calendered, heat set, oil and water repellent, antistatic, and PTFE membrane laminated
• Antistatic Option: Conductive antistatic variants available for ATEX compliant dust collection environments; typical surface electrical resistance 10⁴ to 10⁵ Ω, subject to media construction, test method, humidity, grounding, and site operating conditions
• Construction: Sewn with high strength polyester or aramid thread, with double or triple stitched seams depending on duty level
• Seam Style: Standard double needle seam, with reinforced seam options available for high stress systems
• Air Permeability: Typically 10–16 m³/m²/min before conditioning, depending on basis weight, surface treatment, and finish
• Chemical Resistance: Good resistance to dry heat, abrasion, and most neutral dry dust environments; limited resistance to strong acids, strong alkalis, hydrolysis, and moist chemical exposure
• Hydrolysis Resistance: Limited; avoid moist, acidic, alkaline, or high humidity operating environments
• Cage Compatibility: Designed for use with standard round or oval cages; compatible with venturi based pulse jet cleaning systems
• Compliance: OEM equivalent constructions available; food contact compliant variants available on request where supported by selected media and documentation requirements, including FDA 21 CFR and EU 1935/2004 & 10/2011
• Add Ons: Wear pads, anti collapse rings, top load guides, reinforced cuffs, spark resistant cuff options, and customised top and bottom constructions
• Pleated Option: Available for space constrained systems where increased filtration surface area, lower air to cloth ratio, and extended service life are required

• Woodworking & Furniture Manufacturing: Reliable capture of sawdust, sanding dust, routing dust, and fine wood particulates in dry extraction systems, helping maintain stable airflow and cleaner production areas.
• Grain Handling & Milling: Dust control for silos, conveyors, transfer points, feed processing, and dry ingredient handling, with antistatic variants available for ATEX compliant environments where combustible dust risk assessment requires static dissipation support.
• Cement Grinding & Minerals Processing: Collection of dry mineral dust, cement dust, limestone dust, and other fine abrasive particulates in moderate temperature systems where polyester needlefelt provides a practical balance of durability and cost efficiency.
• Steel Fabrication & Metalworking: Filtration support for dry grinding dust, cutting dust, polishing dust, and cooled metal particulates, subject to proper spark control, temperature management, and system design.
• General Industrial Dust Collection: Suitable for manufacturing plants, packaging lines, powder handling areas, material transfer systems, and general dry process ventilation where dependable polyester dust bags are required for everyday dust control.
