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.
Introduction to Dust and Fume Collection in General Fabrication
After years of industrial decline, manufacturing in the United States and many other countries is seeing a comeback. Manufacturers are finding the advantage of having suppliers close to home. Technological advances have helped to bring costs down, as well. General fabrication operations are humming, and the near-term outlook is positive.
General fabricators face many challenges, from staying on top of orders to keeping up with technology. One challenge that is not going away is complying with air quality regulations and maintaining a safe and clean workplace. Controlling dust and fumes requires constant vigilance. Highly performing dust collectors are a must in an active facility. Ideally, those dust collectors would be flexible or modular, as well, to accommodate changing floor layouts.
