What is a fume extraction system and when do you need one? Learn how industrial fume extraction protects workers, equipment, and project timelines.

Invisible doesn't mean harmless. On major construction and industrial sites, air quality can be one of the most overlooked hazards. Yet fumes from welding, painting, diesel engines and other operations pose serious, long-term risks to worker health. That's where a fume extraction system becomes more than just equipment. It becomes the company’s frontline defence.
Understanding how a fume extraction system works—and when it's needed—goes a long way in helping manage airborne hazards on busy worksites. These systems are commonly used across a range of Australian industries to support healthier, safer working environments, particularly in settings where fumes pose a long-term risk to workers.
A fume extraction system helps remove harmful airborne particles before they have a chance to circulate through a work site. By pulling fumes directly from the source—whether it's welding, painting, or diesel equipment—these systems help reduce the risks for anyone working nearby.
Fume extraction systems usually involve a mix of fans, ducting and filters, but what really matters is how they are set up and used. In enclosed or partly enclosed areas, airflow alone is not enough. You need targeted extraction that clears the air where people are working and helps sites to meet the standards expected across Australia.
Two of the most common hazards we see are welding fumes and paint fumes. Welding fumes contain fine metal particles that can penetrate deep into the lungs. Prolonged exposure is linked to serious conditions, including lung cancer. Meanwhile, paint fumes can irritate the eyes, skin, and respiratory system and even cause long-term damage to the nervous system, liver, or kidneys.
Add in diesel engine exhaust, which is considered carcinogenic by Safe Work Australia, and the danger grows. When these fumes build up in confined areas like tunnels, basements, or ship interiors, the risks increase exponentially.
Fume hazards don't just fade away on their own. Without an industrial fume extraction system in place to control them, the impact can be felt across your entire worksite, from worker health to equipment performance.
Without an effective fume extraction system, your workers are exposed to a cocktail of irritants and toxins day after day. It might start with minor symptoms—headaches, skin irritation, or a runny nose—but over time, exposure can lead to serious conditions like occupational asthma or long-term respiratory illness and even contribute to life-threatening outcomes.
Fumes and airborne particles can settle on machinery and sensitive electronics and can cause wear, corrosion or performance issues. In industries using high-precision gear like laser cutting or electronics, this contamination can lead to faults, unexpected downtime, or costly repairs.
Letting fumes escape into the open air through doors, vents, or windows just moves the problem outside. It can impact nearby workers and the local community and will contribute to air pollution.
It’s important to note that extracting fumes but not properly filtering them is just relocating the hazard instead of removing it. Depending on the setup, different filters like HEPA or activated carbon should be used to trap harmful particles and gases before the air is either released or recirculated.
Investing in the right fume extraction system helps prevent all of this. With the right system, you protect people, preserve your equipment, and do the right thing for the environment around your site.
You should be looking at a fume extraction system if your site involves any activity that produces airborne contaminants, such as welding, spray painting, abrasive blasting, or diesel-powered machinery. It is especially critical in enclosed spaces, where natural ventilation is not enough.
Many sites still treat ventilation standards as a simple compliance checkbox, but RVT takes a different approach. We see proper fume extraction as part of a wider health-first strategy that protects workers and minimises downtime.
When it comes to controlling fumes on industrial or construction sites, the right setup depends on the type of work being done, the layout of the site, and how the air moves through the space. Here are the common types of fume extraction equipment used across Australian worksites.
These are great for sites that need flexibility. They can be moved between areas, so they are ideal for short-term jobs or changing environments.
A more permanent setup, centralised fume extraction systems connect multiple workstations to a single extraction unit. These are best suited for large-scale facilities where consistent fume control is needed site-wide.
These are built-in work surfaces with integrated extraction, ideal for tasks like grinding, sanding or soldering. They pull fumes and dust down and away from the breathing zone.
No two worksites are the same, which is why cookie-cutter solutions often fall short. That's why RVT's engagements always begin with a full consultation and site assessment. Through our Hazard-Control-Execute process, we identify the specific hazards, tailor the extraction system, and trial it onsite before commissioning.
This level of detail is vital. For example, an exhaust fume extraction system used in a tunnel must account for duct length, power source, and airflow requirements. This is something that our team at RVT has extensive experience in. For BAE Systems Australia, we engineered a 60-metre ducting solution to safely remove fumes from deep within the ship, which is not something off-the-shelf solutions can handle.
Protecting your team is not a box to tick but a long-term investment in your workforce, your project timelines, and your company's reputation. When workers can breathe safely, they can show up consistently and projects can keep moving.
RVT is here to help you make that happen. Our technical consultants do not just deliver equipment – they stay engaged throughout your project. From initial site visits to 24/7 monitoring support, we make sure your solution continues to perform.
