01

If your production process generates smoke, fumes, or airborne dust, you already know it is a problem. What is less obvious is just how much the right extraction system can do beyond simply keeping the air clean.

Donaldson BOFA portable fume extractors are designed to filter potentially harmful airborne emissions produced by processes like laser cutting, electronics soldering, printing, and 3D printing. The contaminants involved can range from fine particles and nanoparticles through to gases and volatile organic compounds, and many of them carry real health risks if left unmanaged.

02

A good filtration system does two things well. It protects your people by keeping airborne contaminants well within safe exposure limits, and it protects your equipment by stopping dust and particulate from settling on machinery and causing downtime. Both of those things have a direct impact on productivity, which is why extraction should be thought of as an operational investment rather than just a compliance tick box.

A sensible starting point is the Safety Data Sheet for any materials you are processing. This will tell you what emissions to expect and help you understand what the relevant workplace exposure limits are in your region.

03

How Does Donaldson BOFA Technology Work?

At the core of every Donaldson BOFA unit is a suction pump that draws airborne emissions through a multi-stage filtration system. That system typically includes patented DeepPleat DUO pre-filtration, a main HEPA filter, and an activated carbon layer to capture vapours and gases. The exact configuration, airflow rates, and filter media will vary depending on the application and the process involved.

Because the units are portable, they can move with your production rather than being fixed to a single point, which makes them a practical fit for flexible or agile manufacturing environments.

What Do the Key Components Actually Do?

05

The DeepPleat DUO pre-filter does the heavy lifting early in the process. It uses a large drop-out chamber to capture high volumes of particulate before anything reaches the main HEPA filter, which significantly extends filter life and reduces running costs.

Airflow management matters too. Donaldson BOFA’s automatic flow control lets operators pre-set airflow rates for specific applications, keeping extraction performance consistent and helping to get the most out of each filter. Reverse flow air technology adds another layer of efficiency by slowing air velocity and changing its direction, so larger particles drop out into the chamber rather than loading up the filter media.

06

Is the System Tailored to Specific Processes?

Yes. Donaldson BOFA extractors are configured around the emissions profile of each application, whether that is laser cutting, laser coding, electronics soldering, inkjet coding, or 3D printing. The chemistry, substrates, and particle characteristics all vary between processes, and the filtration solution is built to reflect that.
