How to Choose a Laser Fume Extractor

Step 1: Identify Your Laser Type

Different lasers produce different types of fumes. This is the most important factor in choosing the right extractor:

CO₂ Laser	Produces smoke, odors, and VOCs from organic materials (acrylic, wood, leather, rubber). Requires multi-stage filtration with activated carbon. → 12 Series ESP-based extractors
Fiber Laser	Produces fine metal dust and fumes. Requires cartridge filtration or high-airflow dust collection. → FH-8 / 8 Series cartridge dust collectors
UV / Green Laser	Low smoke volume but very fine particles. Requires compact, high-precision filtration. → 12-1
Diode Laser	Similar to CO₂ but lower power. → 12-1 or 12-11 depending on scale

Step 2: Understand Filtration Technology

ESP (Electrostatic Precipitation) — 12 Series

• Charges particles electrically, collects on washable plates
• 96-99% efficiency on 0.1-10μm particles
• Excellent for oily/sticky laser fumes
• Washable, reusable filters — 50-70% lower long-term costs
• Consistent airflow, quieter operation
• Enhanced with UV lamps for ozone decomposition

Cartridge Filtration — FH-8 / 8 Series

• PTFE membrane cartridges trap dry particulates
• 99.9% efficiency at 0.3μm
• Pulse back-blow system for automatic filter cleaning
• Designed for metal dust from fiber cutting and welding
• 24-hour continuous operation capable

Step 3: Match Airflow to Machine Size

Small desktop / 6040	300–500 m³/h	12-1, 12-11, DF-2
Standard 1390 CO₂	1000–1500 m³/h	12-4, 12-5
Standard 1325 CO₂	1500–3000 m³/h	12-4S, 12-5S, 12-3
Fiber cutting (3kW)	4000–6000 m³/h	8-2
Fiber cutting (6kW)	6000–8000 m³/h	8-3
Fiber cutting (12kW+)	8000–11000 m³/h	8-4
Multi-machine cluster	Synchronized units	12-8, 12-9 (modular)

Step 4: Consider Your Operating Environment

• Office/studio? Prioritize low noise (≤65 dB). → 12-1, 12-11, DF-2
• Industrial 24/7? Need robust design, pulse cleaning. → FH-8S, 8-2/3/4
• Multiple operators? Adjustable airflow, modular. → 12-5C, 12-8/9
• Education? Simple operation, easy filter replacement. → 12-11
