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 for Electronics Manufacturers
The electronics manufacturing industry is one of the largest industries in the world, and it continues to grow. The staggering numbers are projected to reach 670 Billion US dollars worldwide by 2018. With numbers like these, anything that offers a competitive advantage to the manufacturer should be considered. But there is one seemingly insignificant component to electronics manufacture that often goes overlooked: dust.
With electronics manufacturing, dust is not just a nuisance—it can be detrimental to factory personnel, as well as to the end product being produced. An electro-static charge in dust can short out components even before they reach packaging. Also, higher concentrations of dust increases the risk of dust combustion. But traditional dust mitigation techniques can fail to meet the demands of the original equipment manufacturer (OEM) factory floor.
