Dust and fumes are easy to ignore until they start getting in the way (like haze hanging in the light, residue settling on finished work, strong odours, or staff noticing irritation). A properly specified dust extraction system or fume extraction system helps control airborne contaminants by capturing and filtering them, rather than letting them circulate around the workspace.
We, at Ducting Express, supply dust extractors, dust collectors, and fume extractors, along with the ducting and capture components needed to build a complete dust and fume extraction setup. Where requirements are straightforward, you may be able to purchase a standard unit. Where there are multiple capture points, ducting changes, or you’re combining dust and fume control, our team can help you narrow down the right parts.
Note: the information on this page is general. The right approach depends on your process, materials and site risk assessment. Please, if you’re unsure, speak to our team before ordering.
Why is effective fume & dust control important?
In industrial and workshop environments, airborne contaminants can contribute to long-term health issues (including respiratory irritation and occupational asthma), and poor control can create knock-on problems like extra cleaning, dusty surfaces, and avoidable downtime. On some processes, fine airborne contamination can also raise wider safety concerns, so it’s worth getting the fundamentals right.
From a compliance point of view, many businesses also need to show they’ve assessed exposure risks and put suitable controls in place, particularly where dust, fumes or vapours are generated during normal work.
Source capture vs. ambient filtration
You’ll generally see two approaches used in workshops:
Source capture
This focuses on capturing contaminants close to the task, for example with hoods, bench capture, canopies, or a fume extraction arm. It’s often the most effective way to limit spread because you’re dealing with the contaminant before it drifts into the wider space.
Ambient filtration / general air cleaning
This focuses on cleaning the background air in the room. It can help reduce “overall haze”, but it’s usually treated as support, not a replacement for capture on the process itself.
A lot of sites end up with a mix: source capture with background filtration.
What you’ll typically see in a dust & fume extraction setup
Most dust and fume extraction systems are built from the same building blocks:
- Capture: hoods, canopies, benches, or a fume extraction arm (common for workstations and welding fume extraction)
- Ducting & fittings: to route air from capture points to the unit
- Extraction / filtration unit: the dust extractor / dust collector / fume extractor
- Consumables: filters, pre-filters and collection options (varies by unit/type)
If you’re comparing options, the “first pass” usually comes down to the practical specs that affect fit and performance.
Specs people compare
Dust collectors / dust extraction units
- Airflow rating (often m³/hr)
- Motor power (kW)
- Inlet/outlet connection size (diameter)
- Filter type and consumables
Fume extraction arms
- Arm length / reach (Kemper arms are available in lengths from 1.5m to 6m, depending on range)
- Arm diameter
- Hood features (damper, rotation/swivel, etc.)
Benefits of HSE-aligned LEV systems
Many extraction setups sit within a wider LEV approach. When the capture points, ducting and filtration are properly matched, you tend to notice:
- Better capture at the work area
- More consistent performance across capture points
- Fewer day-to-day annoyances like frequent blockages or rapid filter loading
- Easier maintenance planning (filters, bags/bins, access points)
What are the regulations?
In the UK, dust and fume control commonly sits under COSHH (Control of Substances Hazardous to Health). In plain terms, businesses are expected to assess exposure risks and put suitable control measures in place, then keep those controls working as intended.
Because requirements vary depending on what you’re extracting and how work is carried out, the safest route is to treat regulation as a framework and specification as site-specific: if you’re unsure what applies to your setup, speak to a competent person and talk to us about what equipment options make sense.
FAQ
What is the difference between dust and fume extraction?
Dust extraction focuses on airborne particulate (from fine dust to heavier debris). Fume extraction often focuses on very fine airborne contaminants generated by processes such as welding or heated work. Many sites need both.
Does my business legally require fume extraction for welding?
Requirements depend on your process and risk assessment. Many businesses use welding fume extraction as part of their controls, especially where welding is carried out indoors or at regular workstations.
How do I choose between a mobile fume extractor and a fixed system?
Mobile units are often chosen for flexibility where work moves around. Fixed systems are often chosen where capture points are permanent or there are multiple work areas. If you tell us how the work runs day to day, we can point you towards sensible options.
What are the COSHH requirements for industrial fumes?
COSHH is about assessing exposure and putting appropriate controls in place, then maintaining those controls. What counts as “appropriate” depends on the substance, the process and how people are exposed.
How often should filters be replaced in a fume extraction system?
There’s no single interval, it depends on fume load, hours of use, filter type and any pre-filtration. If performance drops or filters block quickly, it may be a sign the filtration approach needs reviewing.
What is an extraction arm and do I need one?
A fume extraction arm is a movable capture device that lets you position the hood close to the work area. They’re commonly used for bench work and welding fume extraction, where the point of generation moves slightly from job to job.
Case studies
Every site has its own mix of processes, layouts and constraints, which is why extraction is rarely “one-size-fits-all”. The case studies below show real dust and fume projects we’ve supported across the UK, including workstation capture and larger ducted extraction systems, so you can see how different approaches work in practice.
