Manual Welding Source Capture

Clean Air Matrix

RoboVent engineers are experts in every category of air filtration and ventilation. The four categories below represent the major options for treating your contaminated air. RoboVent has designed solutions for each of these categories and has manufactured air filtration systems of unrivaled quality.

For more information about these categories, see Indoor Air Quality 101.


Large blowers and air filtration equipment draw contaminated air from the plant (typically at the ceiling level), filter it and return it to the plant. This is a proven solution in plants welding large parts with overhead cranes. It reduces the haze in the air, resulting in a cleaner working environment, with no negative pressure or heat loss.


Air in the immediate area of the welding activity is captured in a hood system, then filtered and returned to the plant. This is the best solution whenever possible. It allows for a more flexible system and removes the smoke directly from the operator's breathing zone. There are many types of source capture, including overhead hoods, crossflow hoods, fume arms and fume guns, some of which work better than others.


Large exhaust fans draw contaminated air from the plant and exhaust it directly into the environment, typically through the roof or walls. This is a traditional method and often results in negative air pressure. Also, it is very difficult to climate-control your plant and the system may not work well in the winter.

Air in the immediate area of the welding activity is captured in a hood, sent through ductwork, and exhausted directly into the environment. This is a lower capital cost alternative to filtration, but tends to result in high operating costs and large, unsightly ducting systems that work less efficiently with modifications. It also results in negative pressure problems.

Manual Welding Source Capture Ventilation Systems

Source capture is a proven way to reduce weld fumes where it is needed most. This involves collecting fumes at the point of welding. There are several ways to do this. A fume arm or overhead hood can pull source fumes out of the breathing zone. The added benefit of a fume arm is the ability to pinpoint the source of fumes and ensure welders stay out of the harm's way. However, a fume arm requires welders to reposition the arm as they work, which doesn't always happen when welders are in a hurry.

Other RoboVent options for source capture include a fume gun that has a capture nozzle integrated directly into the welding gun. This device captures fumes at the point of creation. Other options, such as backdraft, downdraft and crossflow products, direct air through a welding station in such a way as to capture fumes and carry them away from the welder.

All of these options are based on RoboVent's decades of experience controlling weld fumes. RoboVent understands welding, and these solutions are suited to MIG, TIG, Stick and Spot Welding. They are also suited for any material you might work with, including carbon steel, aluminum, stainless steel and specialty metals. RoboVent's engineering staff can work with you to design a system that best fits your process and your budget.
