Streamline Hood

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.

Modular Fume Hoods for Welding Cells

The RoboVent Streamline Hood is a simple solution for enclosing robotic welding cells. This modular hood system covers a welding cell and captures the weld fumes for conveyance through the duct work system to the connected collector. In the collector, weld fumes are sent through high-efficiency Endurex filters, removing airborne contaminants and returning cleaner air to the plant. Choose from standard strike plates for spark protection or upgrade to the optional Delta3 Spark arrestance system for ultimate spark control.

The Streamline Hood is installed on site, and is custom sized to exactly fit over the weld cell it covers. Recent advances have made the hood slimmer and more efficient, taking up less space while delivering major benefits. As with previous models, the hood can accommodate single or multiple robot systems with a variety of configurations, including turntable, Ferris wheel or headstock/tallstock. The unit's low profile is perfect for facilities with overhead cranes. A clear top allows light into the enclosure. Interior cross-supports can accommodate lighting fixtures. And everything is built with RoboVent quality for exceptional durability.

This convenient system ships flat for easy transport, delivery and storage. The modular design uses economical standardized parts that can be easily assembled, disassembled and reused. Installation and modifications are quick and easy.
