Mobile Fume Extractor with Activated Carbon for Welding VOC Removal
This mobile fume extractor effectively captures welding fumes and metal particles at the source during MIG/TIG/arc welding, plastic welding, and brazing operations. The integrated activated carbon filtration system adsorbs VOCs, organic vapors, and odors including benzene compounds, aldehydes, and ketones generated during welding processes.
Technical Specifications
Air Volume
800-2500 m³/h
Negative Pressure
≥2000 Pa
Particulate Efficiency
≥99.97%@0.3μm
Activated Carbon Filling Amount
10-80 kg
Activated Carbon Iodine Value
800-1200 mg/g
Power Supply
220V/380V, 50/60Hz
Core Structure and Key Configuration
Mobile Chassis: Industrial casters with brakes and push handle for flexible movement across multiple workstations
Suction Arm: 2-3m long, high temperature resistant (≥150℃), 360° rotation with hover positioning capability
Three-Stage Filtration System
Pre-filtration: Metal mesh / G4 paint mist cotton protects downstream filter elements
Main Filtration: H13/H14 HEPA or PTFE membrane filter elements for highly efficient dust removal
Activated Carbon Filtration: Granular activated carbon, honeycomb activated carbon, or activated carbon cloth with filling amount matched to airflow; high iodine value coconut shell activated carbon optimized for low concentration VOCs
Fan and Control System
High-pressure centrifugal fan with variable frequency speed control
Differential pressure gauge/alarm indicates filter element replacement timing
Optional pulse backflushing cleaning system available
Safety Design Features
Flame arrester and anti-static grounding
Explosion-proof fan suitable for welding with flammable solvents
Core Advantages
Flexible and Mobile: One-click relocation and rapid deployment reduce infrastructure costs
Dual Purification: Simultaneously addresses particulate matter and VOCs/odors, improving workshop air quality
Air Volume Selection: Choose according to welding process and materials (≥1000 m³/h for single welding torch, higher for multiple torches or large workstations)
Activated Carbon Type: High-iodine-value coconut shell activated carbon preferred; honeycomb activated carbon recommended for high concentration organic waste gas due to lower air resistance and faster adsorption
Safety Requirements: For working conditions with many sparks, explosion-proof fans + flame arresters + anti-static design are essential
Maintenance Points
Clean the dust collection hopper regularly
Pre-filter is washable for repeated use
Replace main filter cartridge when differential pressure alarm sounds (Typical ΔP ≥800 Pa)
Activated carbon requires replacement or regeneration after saturation (Typical replacement cycle: 3-12 months depending on VOC concentration)
Daily inspection of suction arm seal and caster condition ensures collection efficiency and safe movement
