Welding Fume Extractor with Large Capacity Dust Collection Box
This industrial dust removal device is specifically engineered for welding, cutting, grinding, and similar working conditions. It efficiently purifies welding fumes while significantly reducing dust removal frequency through its ultra-large capacity dust collection box, enhancing continuous operation capability.
Technical Specifications
Air Volume
1500-5000 m³/h
Filtration Efficiency
≥99.9% (0.3μm particles)
Dust Collection Box Capacity
50-200 L
Inhalation Arm Length
2-4 m
Motor Power
2.2-7.5 kW
Cleaning Method
Automatic pulse backflush (0.4-0.6 MPa)
Equipment Weight
150-500 kg
System Structure and Key Components
Main Body: Thickened steel plate frame with casters (mobile) or fixed base options
Suction System: 1.5-4m flexible suction arm with 360° rotation and arbitrary hovering, equipped with flame-retardant nozzle
Filtration System: PTFE membrane filter cartridges (flame-retardant, temperature-resistant, easy to clean), 1-6 sets configured according to air volume requirements
Dust Removal System: Automatic pulse backflushing controlled by PLC with timed/differential pressure triggering for thorough dust removal
Dust Collection System: Large-capacity drawer/hopper dust collection box with sealing and quick-release buckle, capacity 50-200L
Power System: Variable frequency centrifugal fan providing 1500-5000m³/h air volume with stable negative pressure and low noise operation
Electrical Control System: PLC + touch screen interface displaying differential pressure and operating status, supporting fault alarms and remote monitoring
Large Capacity Dust Collection Box Advantages
Reduced Downtime: Standard models (10-30L) require frequent emptying; large capacity models (50-200L) support continuous 8+ hour operation and multi-station/high-dust welding applications
Lower Maintenance Costs: Reduced manual dust cleaning frequency lowers filter clogging risk and extends filter lifespan
Heavy-Duty Compatibility: Suitable for high-dust scenarios including MAG/CO₂ welding, carbon arc gouging, and robotic welding operations
Sealing Performance
The dust collection box, air duct, and filter elements feature high-performance sealing designs that eliminate air leakage, smoke leakage, backflow, and secondary dust generation. This ensures all flue gas is properly filtered without contaminating the workshop environment.
Energy Efficiency and Economy
This welding fume extractor utilizes a high-efficiency, energy-saving motor that consumes 15%-30% less electricity than traditional fans. Capable of continuous 8-hour operation, it delivers low electricity costs. The reusable filter cartridges can be cleaned repeatedly, resulting in minimal consumable costs over the equipment's lifespan.
