The arm diameter affects the airflow capacity and efficiency of capturing contaminants. Larger diameters, such as 8 inches, allow for higher airflow and are suitable for heavy-duty applications with more fumes or dust, while smaller diameters like 6 inches are more suited for lighter tasks or smaller spaces. The best choice depends on the type of contaminant and the required airflow. For instance, the Lincoln LFA 4.1 (13 FT) FUME EXTRACTION ARM K1655-2 features an 8-inch diameter, ideal for robust fume control, while the KEMPER - 7 FT. FLEXIBLE EXHAUST ARM, DIA. 6" - 7910201 offers a 6-inch diameter for moderate applications. Multiple diameter options ensure you can select the right arm for your specific extraction requirements.
