When it comes to collection and extraction systems, the two primary options are source capture and ambient air systems. Facility infrastructure and space are significant factors when selecting the system type that best suits a situation.
In some plant environments, circumstances will require an ambient air ventilation system. These systems are very effective in improving air quality for an entire facility.
Three things to remember …
- Ambient air filtration systems come at a variety of costs but their operation requires more filters and more air flow, which leads to higher energy costs.
- Ambient systems don’t remove pollutants from the air until after they’ve entered a workers’ breathing zone.
- Often source capture devices are needed as part of the overall air filtration plan.
To remove pollutants, source capture systems are incorporated into individual workstations. They provide efficient means of improving indoor air quality by collecting dust, fumes, and smoke at point-blank range. This approach ensures that hazardous materials never reach the breathing zone of the worker or other neighboring workers.
