What’s the main function of a dust containment system?
Dust containment systems protect your personnel from contact with hazardous dusts during the manufacturing process and during maintenance of the containment system. They also prevent cross-contamination by keeping dusts from being dispersed into the environment.How does a dust containment system differ from a traditional filter system?
Dust containment systems use a cyclone pre-separator to capture hazardous dusts. There’s still a HEPA filter (sometimes two), but 99% of dusts are stopped before they reach the filter. This provides better protection for your personnel and your products, as well as extends the life of your HEPA filters.When should I move to a dust containment system?
Dust containment systems are used in manufacturing operations that use highly toxic APIs. We recommend a dust containment system when APIs fall into occupational exposure band (OEB) 3 or higher.What process equipment can a dust containment system be used with?
A dust containment system can be used with any tablet press, capsule filler, blistering machine, or other equipment used in the manufacture of pharmaceuticals. They’re also used as centralized vacuum systems serving multiple rooms at the same time where cleaning of equipment (machine parts, accessories, etc.) is carried out.Should I use one HEPA filter or two?
Following the cyclone in a dust containment system, the air flows through a HEPA filter to catch the last 1% of dust and guarantee that no hazardous materials can contaminate the environment. While for many applications a single HEPA filter is sufficient, for highly toxic APIs, we recommend using two. The second filter, called the “police filter,” is a safeguard in case the main filter becomes compromised in any way.Are the systems local or part of a centralized vacuum system?
A dust containment system can be either local or centralized. However, we recommend a local system for three primary reasons:- Local aspiration prevents product propagation and cross-contamination.
- Maintenance work can be carried out in the production room.
- Local systems use shorter pipelines/hoses, which are easier to clean.
