What are fume extraction systems and how do they work?

What are fume extraction systems?

Fume extraction systems are machines that use fans to extract dust, toxic fumes and other harmful particles into a contained filtration system. Fume extractors protect people, equipment and the wider environment from these toxic fumes. For further information see our guide on ‘Why fume extraction is important?’. 

How do fume extractors work? 

Fume extractors have powerful fans that suck in the contaminated air and draw in all of the particles at the same time. The air that has been extracted is cleaned as it is passed through a filter (or series of filters). Finally, the now-clean air is released back into the room. 

This highly efficient process is possible thanks to the strength of the extractor fans and the clever design of the fume extraction filters. These two components work together to remove the harmful fumes and particles so effectively that the air is safe to immediately return to the atmosphere.

Where would you use a fume extraction system?

Many processes such as soldering, welding, sanding, grinding and spraying release hazardous particles into the air. We’re going to take a look at some specific areas where fume extraction systems play a crucial role.

Lasers

Laser technology is used in a range of manufacturing environments. Processes like laser cleaning, laser engraving and laser cutting all release contaminants into the air. These contaminants include harmful dust and fume particles that need to be removed for the health and safety of those nearby.

BOFA has designed a number of fume extraction systems that are specifically designed to remove airborne contaminants from laser technology. With advanced filtration and flow rate control, you can rely on BOFA fume extractors to protect you from harmful contaminants.

Electronics

Fume extraction in the electronics industry is essential because the frequent use of cleaning agents, solvents and resins can release many harmful chemical fumes into the air. These fumes can cause serious health issues over time, so being able to extract them is vital.

Some electronics manufacturing may require soldering to join components together. Soldering releases a number of harmful fumes, which means fume extraction systems are needed to ensure a safe working environment.

3D printing

3D printing has become extremely popular in recent years. For this reason, it’s important to address the hazards that come with using this technology. 3D printers create customisable products at a low cost and with minimal waste, but in the process, they release fumes, combustible dust and strong odours into the air.

In large-scale situations where multiple 3D printers are working simultaneously, the risk to health and safety rises exponentially. BOFA has designed fume extraction systems specifically suited for 3D printers. They utilise compact units with optional speed control to provide clean, filtered air to breathing zones. 

Mechanical engineering

Mechanical engineering often includes metalwork, which releases particularly harmful contaminants that can cause both short and long term health issues. Specialist, powerful fume extractors are required to protect employees from eye injuries, respiratory disease and skin problems.

BOFA’s DustPro fume extraction models remove even the smallest particles during the most intensive mechanical engineering work. These reliable systems can be adjusted to suit the needs of your specific workplace, allowing you and your team to minimise downtime and maximise efficiency.
