Welding Fume Purifier
Introduction
Welding fume purifier is an environmental protection device specifically designed to collect, filter, and treat harmful fumes, dust, and gases generated during the welding process. It is widely used in fields such as metal processing, manufacturing, and automotive repair.
Core Functions of Welding Fume Purifiers
1. Purify Harmful Substances The smoke generated during welding contains heavy metal particles (such as lead, cadmium, chromium), toxic gases (such as carbon monoxide, ozone, nitrogen oxides), and fine dust with a particle size of less than PM2.5. The welding fume purifier intercepts these pollutants through a high - efficiency filtration system, preventing them from spreading into the working environment.
2. Protect Health Long - term inhalation of welding fumes may lead to occupational diseases (such as pneumoconiosis, metal fume fever, respiratory diseases). The purifier can significantly reduce the health risks of workers.
3. Ensure Environmental Protection Compliance It helps enterprises meet national environmental protection regulations (such as the "Air Pollution Prevention and Control Law") and occupational health standards (such as GBZ 2.1 - 2019), avoiding penalties.
Products Parameters
| Parameter | Typical Value | Description |
|---|---|---|
| Airflow | 1000-10,000 m³/h | Determines the processing speed of the system. |
| Filtration Efficiency | ≥99% @0.3µm | HEPA standard for capturing fine particles. |
| Noise Level | 65-75 dB | Low-noise models can be ≤60 dB. |
| Power | 1.5-15 kW | Higher power is required for centralized systems. |
| Filter Life | 6-24 months | Depends on usage frequency and dust load. |

Core structure and working principle
Of Lemar Welding Fume Purifier
1.Air suction device
◦ Capture smoke through the air suction hood, air suction arm or side suction port. The wind speed should reach 0.5 - 1.5m/s (adjusted according to the smoke density).
2. Multi - stage filtration system
◦ Pre - filter: Intercept large particles (≥5μm) to extend the lifespan of the main filter element.
◦ Main filter (critical): ■ HEPA filter cartridge: Filtration efficiency is 99.97%@0.3μm (such as PTFE coated filter media). ■ Activated carbon layer: Adsorb harmful gases (such as formaldehyde, benzene series).
◦ Electrostatic precipitation (optional): Capture sub - micron particles through a high - voltage electric field.
3.Power System
◦ High-pressure centrifugal fan (wind pressure 2000 - 5000Pa) to ensure negative pressure suction.
4. Dust Cleaning Mechanism
◦ Pulse reverse blowing: Automatic dust cleaning with compressed air, suitable for continuous operation.
◦ Manual vibration: Commonly used in economic equipment.
5. Discharge/Recovery
◦ Clean air can be directly recycled indoors (meeting standards) or discharged outdoors.
Products Maintenance
• Routine Maintenance: Clean the pre-filter every week and check the clogging of the filter cartridge every month.
• Filter Element Replacement: Replace the filter element when the differential pressure gauge shows ≥1000Pa.
• Safety Warning: Do not use non-explosion-proof models in an environment with flammable gases.
