Camfil Air Pollution Control partnered with a major auto parts manufacturer that used dust collectors to ensure clean air in robotic welding cells. The collaboration led to a significant reduction in maintenance downtime for the dust collection systems. The facility’s operators initially believed they had the most advanced system available, as the previous vendor provided detailed computational fluid dynamics (CFD) data showcasing airflow performance. Their goal was to prove that the system was designed to prevent fires effectively. However, the reality turned out to be quite different. The installed dust collection systems caused frequent downtime, high maintenance costs, and even internal fires within the collectors themselves. This posed a serious challenge for the company, affecting both productivity and safety. The company faced recurring issues with its dust collectors, which often led to production halts lasting several days due to fires. When pressure built up inside the collectors, the fans would activate, making it impossible to perform pulse cleaning on the filters. As a result, staff had to shut down the systems manually during lunch breaks and other short intervals, causing at least two hours of daily downtime. Additionally, the filters required replacement every six months, increasing both time and operational costs. The noise from the fans also became a concern, leading to complaints from nearby residents. The fans themselves were prone to overheating, requiring frequent and expensive replacements of 50-horsepower motors. Maintenance was further complicated by the outdoor location of the collectors, especially during winter when access became difficult. Faced with these challenges, the facility managers sought a more reliable partner for their dust collection needs. Camfil APC’s Wayne Zimmer stepped in by bringing a Gold Series dust collector demo trailer to the site. This allowed the team to see firsthand the ease of maintenance and filter removal features of the new system. Camfil APC then introduced a completely redesigned ductwork system along with a new Gold Series dust collector tailored for the welding cells. This system enabled safe recirculation of filtered air back into the plant, thanks to integrated safety monitoring filters. Thanks to the improved efficiency of the new system, the manufacturer hasn’t needed to purchase new filters in over three years. There have been no fires in the collectors, and no additional maintenance has been required for the fans or electrical systems. Impressed by the results, the company decided to install two more dust collection systems from Camfil APC. To learn more about how this transition unfolded, watch Zimmer in this video titled “Preventing Downtime for Filter Cleaning.†Welding and cutting operations—whether manual or automated—release harmful fumes made up of tiny airborne particles that can contaminate workshop air and pose serious health and safety risks to workers. Activities like arc gouging, plasma cutting, and laser cutting generate these fumes, and the amount increases with higher production levels. The best way to reduce exposure to hazardous metalworking fumes is through well-designed dust collection systems equipped with high-efficiency primary cartridge-style filters. In some cases, secondary safety filters may also be necessary to capture specific particulates. Many welding facilities, like this auto parts manufacturer after installing customized Camfil APC systems, choose to recirculate the cleaned air back into the workspace. However, the reintroduced air must remain below OSHA permissible exposure limits (PELs) for metal contaminants produced during welding processes. Facilities that exhaust air outdoors must also meet EPA emission standards. OSHA PELs are based on an eight-hour time-weighted average (TWA) for metals found in welding fumes. These standards determine the minimum filtration efficiency required for dust collectors. Even if the air meets PELs, some workers may still experience health effects from exposure. In such cases, stricter exposure limits may be necessary to ensure safe indoor air quality. The EPA’s National Emission Standards for Hazardous Air Pollutants (NESHAP) Rule 6X regulates facilities that vent contaminated air directly outdoors. It covers hazardous air pollutants from metal finishing processes, including cadmium, chromium, lead, nickel, and manganese. Cartridge filtration is recognized under NESHAP Rule 6X as an acceptable control method to eliminate visible emissions. Installing dust and fume collectors with high-efficiency cartridge filtration systems, such as the Camfil APC Gold Series industrial dust collectors, helps welding facilities stay in compliance with EPA regulations.
