Portable Weld Fume Smoke Extraction

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.

Portable Weld Fume Extractors for Smoke Ventilation

Source capture of smoke and fumes from light-duty welding or processes such as cutting or finishing often pose an aggravating challenge. However, source capture is still the most efficient method in these cases to maintain a clean air environment. Stationary equipment is restrictive, and portable units are often ineffective—until now. RoboVent has developed VentBoss, an innovative line of high-quality, portable smoke and fume collectors that are ideally suited to a range of ventilation operations.

These units ensure that welders have protection wherever and whenever they need it. The entire facility benefits, as well, when a welder can capture weld fumes at their source. Limiting the circulation of weld fume particulates, many of which contain elements such as Chromium, Manganese, Nickel and Zinc, is critical for worker health and productivity. It also enables you to meet, or better yet exceed, standards put in place by regulatory groups such as the Occupational Safety and Health Administration (OSHA).
