Why is fume and dust extraction necessary?
Fume extraction technology plays an important role in helping companies both manage their working environment and improve productivity.
Portable systems developed by Donaldson BOFA help to filter potentially harmful airborne emissions that may be generated by specific processes and applications, including laser, electronics, printing, Incremental manufacturing and 3D printing.
Airborne contaminants can include both particles (including nanoparticles) and gases (including volatile organic compounds). Vapour filtration technology can help employers implement health strategies in the working environment. A properly installed and maintained filtration system can also make a positive contribution to productivity by filtering out dust and particles that could otherwise contaminate equipment and potentially lead to downtime.
The first step in a risk assessment is to read the Safety Data Sheet to understand the nature of any emissions associated with the process, while checking local regulations governing exposure levels in the workplace.
At Donaldson BOFA, we have extensive experience in working with industry to find the most appropriate filtration solution for given processes. We can help identify the type, volume, size, shape and velocity of particles being emitted and present managers with filtration system options to consider.
How does Donaldson BOFA technology help in working environments?
Donaldson BOFA vapour and dust filtration technology helps filter air pollutants emitted from a range of industrial processes. And because Donaldson BOFA units are portable, they can support flexible production environments.
Donaldson BOFA systems feature a suction pump that draws air emissions into advanced filtration technology. The systems include the patented DeepPleat DUO pre-filtration, a HEPA main filter and an activated carbon layer to filter vapours and gases. The exact configuration, airflow rate and filter media will depend on each application and the industrial process involved.
What are the basic functions of the key components?
DeepPleat DUO pre-filter technology incorporates a large-volume settling chamber to filter large volumes and a variety of particulates prior to the main HEPA filter. This system helps to optimise the life of the HEPA filter.
Airflow is also an important component of extraction performance. The automatic flow control feature on Donaldson BOFA units allows operators to pre-set airflow rates for specific applications, helping to optimise HEPA filter life cycles.
Reverse flow technology can also contribute to filter performance. It facilitates a decrease in velocity and a change in air direction, which means that larger solid particles fall out of the air stream into the settling chamber. With fewer solid particles entering the filter medium, filter life is optimised.
Does the filtration system differ depending on the application?
Donaldson BOFA systems are designed to deal with process-specific emissions, including laser cutting, laser marking, electronics soldering, inkjet printing and 3D printing. Each solution takes into account processes, substrates and chemical interactions.
