FumeArms & Extension Booms

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.

FumeArms are a versatile and simple solution for capturing smoke and fumes from welding and other industrial processes. Available in 6"(15.24cm) and 8"(20.32cm) diameters, FumeArms are designed to move easily into position to extract smoke and contaminated air from a worker's breathing zone. Unlike many competing brands, RoboVent FumeArms are designed for industrial applications. They are durable, robust and virtually maintenance free. All joints are on the outside of the arm, not in the dirty airstream. All metal surfaces are powder coated to protect against scratches. RoboVent FumeArms are self-supporting, with smooth, low-friction control, and require minimal maintenance.

Extension Booms

RoboVent extension booms are designed to extend the reach of the RoboVent FumeArms, providing up to a 28 feet(8.53m) radius of combined coverage. The extension booms are heavy-duty, welded construction with a durable powder-coat finish. All booms include a bracket for securing the boom to a wall or post, and a heavy-duty flange to attach the FumeArm. Available in 6"(15.24cm) and 8"(20.32cm) diameters, the booms come in both single- and double-articulated versions with a reach 7 feet(2.13m) to 14 feet (4.27m) as standard. Ask your solution specialist if other options are required for your application.
