Why Graphtec GB’s Laser Cutter Needs an Purex Extraction & Filtration System

If you’re using a CO₂ laser cutter or engraver  -  whether in a school, workshop, or studio- there’s one piece of equipment you shouldn’t overlook, and this is an extraction and filtration system.

It might not seem like the most exciting part of your setup, but trust us — it’s essential. We’ll talk you through the reasons behind why it’s so important.

Why Extraction & Filtration Matter

When you cut or engrave materials like wood, acrylic, leather, or PVC Free plastics, the materials are burning/vaporising. That creates toxic fumes (like formaldehyde or VOCs) and fine airborne particles. Without proper extraction, all those fumes end up in your workspace and getting breathed in.

A good purifier system protects everyone nearby. Breathing in laser-generated fumes and particles can cause health problems. An extractor with HEPA and activated carbon filters keeps your air clean and your team safe.

Fire Hazards: Preventing Smoke Build-Up

Not only is there a health risk when not using an extraction system, but a fire risk too. Those fumes and dust can be flammable, especially when cutting wood or card. Good airflow and proper extraction help prevent smoke build-up, cools down the machine, and lower the risk of flare-ups.

Smoke and dust don’t just float around; they stick to everything. That includes your laser lenses and mirrors, which can reduce your cutting power and accuracy.

With good extraction:

• Your optics stay cleaner
• Your machine runs smoothly
• Your cuts look sharper
• Your products look better
   

So this is a win-win.

COSHH Compliance & Insurance Requirements 

In the UK, COSHH regulations (Control of Substances Hazardous to Health) apply to fumes and particles from laser processing. If you’re running a laser cutter commercially or in an education setting, you’re required by law to control those emissions.

A good extractor keeps you on the right side of the law—and keeps users, inspectors and insurers happy too.
