KUA Fume Extraction Arms

KUA Fume Extraction Arms - The Nr. 1 choice of our customers

Clean air starts at the source

The KUA is not just any fume extraction arm — it’s a proven solution for welding fume extraction arms in industrial environments. The KUA fume extraction arms are the go-to solution for small to heavy-duty workplaces. Designed to extract welding fumes, gases, and oil mist contaminants right at the source, both the KUA-160 and KUA-200 provide a healthier, cleaner work environment. With tube diameters of 160 mm (6.3 in) or 200 mm (7.9 in) and available in 2, 3 or 4 meter lengths, these flexible extraction arms are suitable for a wide range of welding and fabrication setups.

Engineered for precision and ease

All KUA arms feature smooth aluminium tubing, external elbow joints and ball-bearing-supported middle joints. This makes them lightweight, easy to move, and stable in any position. The 360° hood grip allows for intuitive adjustment, helping operators position the arm exactly where it's needed — in one simple motion.

• High airflow capacity
• Minimal resistance thanks to solid tubing
• Low noise output
• Maintenance-friendly construction
• Available in ATEX version for explosive environments

Recommended applications

KUA arms are also widely used as reliable welding fume extraction arms, offering direct source capture to protect welders from hazardous particles. This makes them ideal for workshops that require strict air quality control during intensive welding operations. As our number one best-selling extraction arm line, KUA arms are widely recommended for:

• Maintenance and production welding
• Workbench applications in confined spaces
• Dust and fume control during cutting and grinding processes
• General air filtration in fabrication and engineering workshops

From compact metalworking stations at Mimault Tôlerie Industrielle to large-scale fabrication shops at AJ Engineering, KUA arms prove their versatility and performance daily. Their flexibility and ease of use make them the ideal choice for any environment where welding fume extraction arms are needed to manage fumes and airborne particles effectively.

Choose the right welding fume extraction arm

Plymovent offers two high-performance extraction arm models to suit different airflow needs: the KUA-160 and the KUA-200.

KUA-160: Light and flexible for general welding

KUA-160 is the go-to solution for small to medium-sized workplaces. With a tube diameter of 160 mm (6.3 in), it is lightweight, easy to maneuver, and perfect for general welding and fabrication tasks. The KUA-160 can be used in two ways:

• As part of a mobile extraction unit, combined with systems like MobilePro and MobileGo plus.
• As a stationary wall-mounted system, in combination with MonoGo plus, DualGo plus or WallPro filter units for fixed workplaces.

KUA-200: High-capacity airflow for heavy-duty use

KUA-200, on the other hand, has a larger 200 mm (7.9 in) diameter and is designed for heavy-duty extraction needs. It allows significantly higher airflow, making it ideal for applications with intense fume generation. This version is compatible with high-capacity fans like the FUA and fixed systems such as WallPro.

Shared benefits of both models

Both models support the most common welding processes, including MIG-MAG, TIG, FCAW, and MMAW. They are also available in an ATEX version for use in explosive environments.

Extend your reach

For larger work areas or hard-to-reach spaces, the reach of KUA arms can be significantly extended using two smart solutions:

• FlexMax Extension Crane: Extend the arm’s working range by 1.5, 2.5, 3.5 or 4.5 meters. Ideal for fixed setups where maximum flexibility is required. Both KUA-160 and KUA-200 are fully compatible.

• ERC Rail System: The ERC Rail System is compatible with the KUA-160 only. It offers 19 ft (5.8 m) of horizontal mobility—ideal for moving the extraction arm for your workshop along large workpieces like boats, trains, or long welded structures.

   

These options make the KUA arms even more versatile and effective in dynamic or spacious working environments.
