Hanging Fume Extraction Arms

A hanging fume arm is a source-capture fume extraction system designed to remove welding fumes, smoke, vapors, gases and light dust directly from the point where they are generated. The arm is mounted to a wall, stanchion, or other structural support and can be positioned near the work area to help keep contaminants away from the operator's breathing zone.

Hanging fume arms are commonly used for welding fume extraction, grinding, soldering, light industrial processes and applications that generate smoke, vapors or gases. They are especially useful when a flexible source-capture solution is needed at a fixed workstation. The appropriate arm diameter, length, airflow and filtration depend on the application.

Yes. Hanging fume arms are a common solution for welding fume extraction because they allow the operator to position the extraction hood close to the welding process. Capturing fumes at the source helps prevent contaminants from traveling through the work area and reaching the welder's breathing zone.

For effective source capture, the extraction hood should be positioned as close to the welding plume as practical without interfering with the welding operation. The required capture distance and airflow depend on the welding process, hood design, arm diameter and surrounding air movement. Keeping the hood close to the source generally improves capture performance.

IAP hanging fume arms are available in 3", 4", 5", 6" and 8" diameters, with standard arm lengths ranging from 3 feet to 14 feet. Available configurations include:  3"x 5', 4"x 5’ & 8’', 5”x 7' & 10', 6” x 7’, 10’ & 14’, 8” x 7’, 10’ & 14’.

The correct fume arm size depends on the application, contaminant, required airflow, distance between the hood and source, and ductwork or filtration system. Larger arm diameters generally allow higher airflow, while smaller arms can be appropriate for more localized applications. IAP provides airflow curves for its hanging fume arms and can help select the appropriate size for a specific application.

Hanging fume arms are typically mounted using a wall bracket attached to a wall, column, stanchion or other suitable structural support. IAP hanging fume arms include the mounting bracket with the arm, so a separate arm bracket does not need to be purchased. Proper structural support and installation should be verified for the specific installation.

Yes. A hanging fume arm can be connected to a filtration system to create a complete source-capture fume extraction solution. IAP offers filtration systems designed to work with fume extraction arms, as well as direct-mount fans for applications where filtered recirculation is not required or where exhaust is handled through another system.

Hanging fume arms are mounted to a wall or structural support and are ideal for fixed workstations. Standing fume arms are mounted to a mobile or stationary base and can be moved around the shop. Telescoping fume arms use a compact sliding design and are particularly useful where workspace is limited, such as small welding booths and technical school welding labs.

Yes. IAP offers stainless steel hanging fume arms for applications requiring corrosion resistance, cleanability or specialized materials. Stainless steel models use 304 stainless steel components and are available in the same general range of diameters and lengths, with FDA hose options for applications such as food processing, pharmaceutical production, and certain chemical environments.
