welding robot dust collection system、Welding robots are fast and precise. However, they generate heavy smoke and fine particles. Without proper fume extraction, factories face health risks, equipment damage, and failed inspections. Today, we share a real case where MoLAND helped an automotive parts manufacturer solve their welding fume problem completely.
The customer is a tier-1 supplier for a major Chinese automaker. Their facility includes 6 robotic welding stations working 2 shifts per day. The main workpieces are chassis frames and body-in-white components.
In short, the old system was not working.

After on-site evaluation, MoLAND designed a centralized dust collection system tailored for robotic welding:
表格
| Component | Specification |
|---|---|
| Main Unit | MLWF360 × 2 units |
| Capture Method | Enclosed hood + side draft arms |
| Ductwork | φ200mm galvanized steel, 45m total |
| Filter Type | Nano PTFE membrane cartridge |
| Filtration Accuracy | 0,3μm pada efisiensi 99,9% |
| Control System | PLC with automatic pulse-jet cleaning |
First, the enclosed hood captures 95% of fume at the source before it spreads. Then, the side draft arms handle overflow during workpiece loading. Moreover, the dual MLWF360 setup provides redundancy—if one unit needs maintenance, production continues uninterrupted.
Our team installed all ductwork during a scheduled maintenance window. We used modular flange connections to minimize welding on-site. This approach ensured faster installation with zero fire risk.
The two MLWF360 units were placed in an outdoor equipment yard. We connected them to the existing power supply (380V/3-phase) and compressed air for pulse cleaning.
The PLC system was programmed to:
We ran a full 8-hour shift test. Results were measured using a professional particle counter.
表格
| Metric | Before | After | Improvement |
|---|---|---|---|
| Workshop PM2.5 | 320 μg/m³ | 28 μg/m³ | 91% reduction |
| Robot sensor failures | 8 times/month | 0 times/month | 100% elimination |
| Filter replacement | Every 2 months | Every 12 months | 6x longer life |
| Worker complaints | 15 per month | 0 per month | Complaint-free |
| Environmental inspection | Failed | Passed | Compliance achieved |
The customer's total investment was approximately ¥180,000. Annual savings include:
Payback period: less than 14 months.
We don't just sell filters. We design capture systems that match your robot cycle time, workpiece geometry, and factory layout.
