Understanding the Basics of Dust and Fume Extraction
Why is fume and dust extraction important?
Fume and dust extraction systems are essential for businesses to maintain a safe working environment and boost overall productivity.
Donaldson BOFA offers portable filtration units designed to capture harmful airborne substances produced during various processes, such as laser cutting, electronics manufacturing, printing, additive manufacturing, and 3D printing. These airborne pollutants can include tiny particles (including nanoparticles) and gases like volatile organic compounds (VOCs).
Effective fume extraction helps companies meet health and safety requirements by controlling exposure to these contaminants. Additionally, a properly installed and maintained filtration system can prevent dust and particles from settling on equipment, reducing the risk of malfunctions and costly downtime.
To properly evaluate the risks, it’s important to consult the material’s Safety Data Sheet (SDS) to understand the emissions involved in specific processes and review local regulations on workplace exposure limits.
With extensive industry experience, Donaldson BOFA assists companies in selecting the most suitable filtration solutions by analysing the type, quantity, size, shape, and speed of the emitted particles, helping managers make informed decisions about their fume and dust control systems.
How does Donaldson BOFA technology improve workplace environments?
Donaldson BOFA’s fume and dust filtration systems effectively capture airborne pollutants generated by a variety of industrial processes. Their portable design makes them ideal for flexible manufacturing setups that require adaptable solutions.
These systems use a powerful suction pump to pull contaminated air into advanced filtration units. The filtration typically involves several stages, including patented DeepPleat DUO pre filters, a high efficiency HEPA filter, and an activated carbon layer to remove vapours and gases. The specific combination of filters, airflow capacity, and filtration materials is customized based on the unique needs of each application and industry process.
What are the main functions of the key filtration components?
The DeepPleat DUO pre filter technology features a large capacity drop out chamber designed to capture high volumes and a wide range of particles before the air reaches the main HEPA filter. This pre filtration stage helps extend the life of the HEPA filter by reducing its load.
Airflow management is also crucial for effective extraction. Donaldson BOFA’s automatic flow control allows users to set precise airflow rates tailored to specific processes, which helps maximize the efficiency and lifespan of the HEPA filter.
Additionally, the reverse flow air technology improves filter performance by slowing down the air velocity and changing its direction. This causes larger particles to drop out of the airflow and settle in the drop-out chamber, minimizing the amount of debris reaching the filter media and further prolonging filter life.
Does the filtration system vary depending on the application?
Yes, Donaldson BOFA designs filtration systems tailored to handle emissions specific to various processes such as laser cutting, laser coding, electronics soldering, inkjet coding, and 3D printing. Each solution is carefully engineered to consider the unique materials, processes, and chemical interactions involved.
