What is a Fume Extraction System?
The fume extractor is for cleaning both particles and gases. It is designed to filter harmful substances, such as hydrocarbon and cyanide, during the process of soldering, tin dipping in the solder pot, welding, laser marking and carving, printing, etc. This allows them to catch harmful laser fumes that will be produced during laser processes. This protects the user from inhaling them and ensures their safety.
Laser Fume Hazards
Laser fumes are produced when a high energy laser beam comes into contact with a substrate such as metal or plastic. The heat from the laser beam provokes the material to release smoke or a plume of laser fumes. The high temperature expands the surrounding air creating airborne microscopic particles. These microscopic particles can become lodged deep within the lungs causing long-lasting health effects.
The particulate and fume by-products of laser engraving and laser cutting operations can be hazardous to both the operator and the laser system itself. Conditions vary depending on the material being marked or cut, but many of these processes can produce respiratory hazards that may lead to acute or long-term negative health effects.

What is the Purpose of Laser Fume extractors?
Manufacturers of these lasers want enough airflow to protect the lenses from the smoke and fumes being produced. There are also health and safety concerns depending on the material types being marked and each material may require different types of filtration. Along with these health and safety concerns you also need an effective mechanical setup to ensure proper capture of the fumes.
