General Fabrication Industry and Dust Collection

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.

Ambient_Filtration

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.

SourceCapture_Filtration

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.

Ambient_Exhaust

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.

SourceCapture_Exhaust
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.

Dust and Fume Collection Challenges in General Fabrication

Air quality concerns in general fabrication originate in common processes such as cutting, machining and welding. As any floor manager knows, dust and fumes can create serious challenges for worker health, plant cleanliness and regulatory compliance.

Welding, in particular, presents serious health concerns, since many weld fumes contain toxic metals. The extreme heat involved in welding creates fumes with metal particulates less than a micrometer in diameter. When toxic particulates are inhaled, their small size allows them to travel deep into the lungs and be absorbed into the body. Hexavalent chromium is a good example of a commonly produced and dangerous weld fume particulate. This substance is a known carcinogen. Without a fume collection system in place, workers are at risk throughout an entire facility.

Besides the pressing concern of worker health, worker recruitment and retention should be on manufacturers' minds, as well. The American Welding Society estimates that manufacturing will see a shortfall of 290,000 skilled welders by 2020. Recruiting and retaining the best workers will become more and more challenging in the near future. A healthy, clean and attractive workplace free from haze and hazards is crucial.

Fires and explosions are other serious concerns for general fabrication operations. The Bureau of Labor Statistics estimates that these events cause about 3% of workplace fatalities. Cutting tables and other such equipment produce dust which can be combustible. A dust collection system can prevent a buildup of dust, and a spark arrestance system can further safeguard a facility from dangerous fires and explosions.

Complying with federal regulations on air quality is another mandate for a general fabrication operation. The Occupational Safety and Health Administration (OSHA) sets these standards to ensure workers have clean air and a safe workplace. For example, welding facilities must comply with air contaminant requirements that address permissible exposure limits (PELs) for specific toxic substances, such as inhalable manganese and hexavalent chromium. Failure to comply with these regulations can lead to serious fines.

Solutions for Dust and Fumes in General Fabrication

RoboVent has its origins in the automotive parts industry and understands the processes and challenges of general fabrication. RoboVent provides affordable equipment and engineering services to make your facility safer, healthier and more efficient.

Lower operating costs with RoboVent equipment are achieved through automated systems. Dust collectors only run when they need to, seriously reducing energy use. No operation can afford downtime caused by a failed or finicky dust collector, so reliability and easy maintenance have been designed into RoboVent equipment. For example, eTell Intelligent controls allow a plant to move beyond preventative maintenance to truly predictive maintenance.

The Spire fume collector is an example of a device well suited for general fabrication. This efficient, space-saving equipment can also be outfitted with a Delta 3 spark arrestor and a Supprex-200 Fire Suppression System to reduce the risk of fires in ductwork. If a facility needs a larger system, the RoboVent Grid ducted collector can easily be scaled up. For applications where a source capture system is not an option, RoboVent also offers ambient collectors like the Vortex Series collector.
