Maxi Centralised Welding Fume System
Up to 80,000 m³/h
Welding fume is 0.01–0.1 μm at source and agglomerates to 1–2 μm in the breathing zone — the hardest and most harmful dust to capture. Maxi uses a turbo fan for high volume at high negative pressure, drawing fume from the whole shop through hoods and ducting, with nano-fibre media rated for 0.3–1 μm.
- Up to 80,000 m³/h for a complete welding shop
- Turbo fan — high volume at high negative pressure
- Nano-fibre media for 0.3–1 μm
- Automatic pulse cleaning, online or offline
- PTFE membrane, anti-static, flame-retardant, repellent
- Explosion-proof option for aluminium and magnesium

|---|---|
| Particle size | 0.01–0.1 μm (1–2 μm in breathing zone) |
| Media | Nano fibre with PTFE membrane |
| Cleaning | Automatic pulse, online/offline |
| Fan | Turbo fan, high volume and negative pressure |
| ATEX | Explosion-proof option |
Single-Arm and Mobile Fume Extractors
Point-of-source extraction
One unit per station. The universal extraction arm reaches directly over the weld and captures at source, with automatic pulse-jet cleaning — the right answer when welders are spread out and stations keep moving.
- Universal arm for capture right at the arc
- Automatic pulse-jet cleaning extends filter life
- Mobile body follows the work
- Suited to dispersed stations and intermittent welding
| Form | Single or twin arm mobile extractor |
|---|---|
| Capture | Universal arm with hood |
| Cleaning | Automatic pulse-jet |
| Filter | Multi-stage, membrane optional |
Carbon Adsorption Fume and Odour Unit
Pre-filter plus carbon, multi-stage
Laser engraving, marking, grinding and welding release odour gases — SO₂, formaldehyde, benzene — as well as particles. A pre-filter takes the dust and activated carbon adsorbs the gases; cartridges pull straight out for replacement and the turbo blower stays quiet.
- Adsorbs SO₂, formaldehyde and benzene
- Multi-stage: pre-filter then activated carbon
- Slide-out cartridges, minutes to change
- Quiet turbo blower with high volume
| Stage 1 | Pre-filter, captures particulate |
|---|---|
| Stage 2 | Activated carbon for gases |
| Change-out | Slide-out cartridges |
| Fan | Low-noise turbo blower |
RTO Incineration and Zeolite Concentration
Three-chamber RTO, 99–99.8%
High-volume low-concentration VOC from coating, chemical and paint duties cannot be filtered — they need thermal oxidation. A three-chamber RTO covers 1–10 g/Nm³ and turns self-sustaining above 1.5 g/Nm³; below 1 g/Nm³ a zeolite rotor concentrates the stream before incineration.
- Three-chamber RTO: self-sustaining above 1.5 g/Nm³, over 99%
- Up to 99.8% above 3 g/Nm³
- Honeycomb ceramic preheats above 760 °C; oxidation chamber ≥800 °C
- 0.5–1 s residence; purge lifts efficiency above 99.5%
- TO with heat recovery for streams above 6 g/Nm³
- Zeolite rotor for low strength, high volume below 1 g/Nm³
| Inlet strength | 1–10 g/Nm³ |
|---|---|
| Self-sustaining from | >1.5 g/Nm³ |
| Efficiency | Over 99%; 99.8% above 3 g/Nm³ |
| Preheat | Honeycomb ceramic above 760 °C |
| Oxidation | At least 800 °C |
| Residence | 0.5–1 s |
| With purge | Above 99.5% |
| TO inlet | Above 6 g/Nm³ |
|---|---|
| TO preheat | About 550 °C, control point 750 °C, 0.5 s burn |
