Process Area Barrier Curtains are a useful tool in improving the containment levels in existing installations and as a method to restrict access.
Down flow booths, for example, work by pulling air across a drum or piece of processing equipment which typically provide a containment level of 100 µg/m³ on an 8 hour time weighted average (TWA) as presented at various containment conferences. The airflow drawn into filter banks is disrupted when an operator is working at this type of station. When that occurs, eddy currents of air and entrapped powder start to swirl which disrupts containment. As such, curtains are a secondary containment tool for risk reduction by isolating the operator's breathing zone from the point of exposure and for protecting the product as well.
Similarly, restricting access to another part of a processing suite has been a demonstrated need as well. Here, a barrier can be added to a doorway, for example, to restrict the flow of personnel between the suites.
The curtains are manufactured from clear ArmorFlex® 113 film that will allow room light to illuminate inside the barrier and not restrict visibility. This rugged film provides a safe working environment while enabling the enhancements developed through numerous installations using this flexible containment technology.
