Product Introduction
Known as 320mm PTFE Pleated Filter Element and Welding Fume PTFE Cartridge Filter, this specialized filtration solution is engineered to capture welding fumes and metal particulates in industrial environments. The 320mm diameter design provides increased surface area in compact spaces, making it ideal for mobile welding stations and centralized dust collection systems handling various welding processes (MIG, TIG, arc welding).
Constructed from 100% PTFE membrane with polypropylene (PP) support layers, the cartridge combines exceptional chemical resistance with high-temperature tolerance up to 160°C (320°F). Its hydrophobic properties prevent moisture absorption, ensuring consistent performance in environments where welding spatter and condensation are common.
Product Features
Pleated Design: Offers 1.8 m² filtration area per 10" length (305mm), maximizing particle capture in limited space compared to non-pleated cartridges.
Filtration Precision: Absolute-rated at 0.1μm to 1μm, removing 99.97% of welding fumes, including hexavalent chromium and nickel particles.
Material Construction: PTFE membrane with PFA hardware eliminates glue contamination, ensuring high purity in sensitive applications.
Temperature Resistance: Operates continuously at 160°C (320°F) with maximum differential pressure of 5.0 bar at 20°C.
Fume Release: Non-stick PTFE surface enables efficient pulse cleaning, reducing pressure drop buildup from sticky welding smoke.
Chemical Inertness: Resists attack from welding flux residues, acids, and cleaning solvents used in maintenance.
Long Service Life: 6–9 month lifespan in heavy welding applications, outperforming polyester cartridges by 2–3 times.
Application scenarios
This 320mm PTFE filter cartridge is essential for welding and metal fabrication environments:
Automotive Manufacturing: Captures fumes from robotic welding lines, protecting workers from metal oxide particulates.
Aerospace Fabrication: Controls aluminum and titanium welding fumes in precision manufacturing facilities.
Construction Welding: Filters fumes from on-site structural steel welding, compliant with OSHA welding fume exposure limits.
Metal Fabrication Shops: Centralized collection for multiple welding stations, handling mixed metal fumes (steel, stainless, aluminum).
Product Advantages
The cartridge offers significant benefits over conventional welding fume filters:
Improved Air Quality: Removes submicron particulates that bypass standard filters, reducing respiratory health risks.
Reduced Downtime: Longer service intervals and faster changeouts reduce maintenance time by 40% compared to bag filters.
Energy Efficiency: Lower pressure drop (initial <0.3 bar) reduces fan energy consumption in dust collection systems.
Versatility: Compatible with most cartridge collectors, requiring no equipment modifications for installation.
Customization Process
Our welding-specific customization ensures optimal fume capture:
Welding Process Analysis: Evaluates material type (steel, aluminum, stainless), amperage, and fume generation rate to recommend pore size.
Dimension Engineering: Customizes length (10"–40"/254mm–1016mm) and end cap configuration (222 O-ring, flange, or thread) for specific collectors.
Membrane Selection: Offers standard or enhanced PTFE membrane based on required efficiency (99.9% vs. 99.97%).
Performance Testing: Samples undergo 500-hour welding fume exposure testing to validate pressure drop and efficiency retention.
Production: Glue-free thermal welding ensures no outgassing, with cleanroom packaging to prevent pre-installation contamination.
