The KUA is a durable aluminum tube extraction arm, built for everyday use in tough workshop environments. Specifically engineered to remove welding fumes, gases, and oil mist directly at the source, this welding fume extraction arm improves air quality and safety where it matters most.
The KUA isn’t just any fume extractor — it’s a reliable extraction arm for workshop environments. Engineered to remove welding fumes, gases, and oil mist directly at the source, both the KUA-160 and KUA-200 help create a cleaner, safer workspace. These flexible models, with diameters of 6 in (160 mm) and 8 in (200 mm), are available in lengths of 6.5 ft (2 m), 10 ft (3 m), or 13 ft (4 m)—ideal for a wide range of welding and fabrication setups.
All KUA arms come with durable aluminum tubing, external elbow joints, and smooth ball-bearing-supported pivot points. This makes each arm lightweight, highly maneuverable, and stable in every position. With the 360° hood grip, operators can reposition the arm in one easy motion—right where it’s needed most.
The KUA is a popular welding fume extraction arm that offers direct source capture, helping protect welders from harmful particles. It’s the ideal extraction arm for workshop spaces where air quality is a top priority. As our top-selling model, the KUA is widely recommended for:
From compact metalworking setups at Mimault Tôlerie Industrielle to large-scale fabrication at AJ Engineering, KUA arms prove themselves daily. Their flexibility and ease of use make them the perfect fit wherever fumes and airborne particles need to be controlled.
Plymovent offers two top-tier models to fit different airflow requirements: the KUA-160 and the KUA-200.
KUA-160 is the ideal option for small to mid-sized workspaces. With a tube diameter of 6 in (160 mm), it’s lightweight, easy to handle, and built for general welding and fabrication jobs. The KUA-160 can be used in two configurations:
KUA-200 features a larger 8 in (200 mm) tube diameter and is built for heavy-duty welding fume extraction. It delivers significantly more airflow, making it the best choice for environments with intense fume generation. This version is compatible with high-capacity fans like the FUA and stationary systems like the WallPro.
Both models support all major welding processes, including MIG-MAG, TIG, FCAW, and MMAW. They’re also available in an ATEX-certified version for use in potentially explosive environments.
Need more coverage? You can extend the reach of your extraction arm for workshop setups with these two smart accessories:
ERC Rail System: The ERC Rail System is only compatible with the KUA-160. It adds 19 ft (5.8 m) of horizontal mobility—perfect for sliding your extraction arm for workshop along long projects like boats, trains, or structural welds. A smart solution when a fixed welding fume extraction arm just isn't enough.
These add-ons make your welding fume extraction arm even more effective in larger or more dynamic environments.

What is the difference between KUA-160 and KUA-200?
The KUA-200 has a larger diameter of 8 in (200 mm), which allows for greater airflow—perfect for heavy-duty welding fume extraction. The KUA-160 is lighter, with a 6 in (160 mm) diameter, and better suited for general use or mobile extraction arm for workshop setups.
Can the KUA be used for welding fumes?
Absolutely. Both KUA-160 and KUA-200 are purpose-built as welding fume extraction arms. They effectively capture harmful fumes right at the source.
Are KUA arms suitable for explosive environments?
Yes. Both models are available in an ATEX-certified version for safe use in environments with explosive gases or dust. Visit our dedicated ATEX page for more details.
What accessories are available?
Optional add-ons include the LEH-10 wide hood for capturing VOCs, the SLE-30 magnetic hose for hard-to-reach spots, and start/stop switches with built-in LED lighting.

Micron was looking for an effective dust control device with filters to ensure easy maintenance. Plymovent was challenged to get the dust levels under control.
In 2017, AJ Engineering secured its biggest contract to date with a multi-million-pound windfarm deal, this was to fabricate and install the structural steel and cladding.
Prior to Plymovent, another manufacturer’s hose-based exhaust removal system was installed. Some issues with the system included faulty installation, poor service, inadequate system performance and safety concerns.
The service workshop needed a high-quality extraction system to remove welding fumes, grinding dust and oil mist, preventing accumulation in the workshop.
K.S. Smede og Montage, a smith’s working-place, was about to expand their business and move to new premises. They took this opportunity to purchase a new ventilation/filtration system.
