This containment control system is engineered for safely
Dispensing from drums and weighing operations are typical applications of the containment-control system (CCS; photo), which contains and controls airborne particulate matter from sampling procedures. Drums or equipment can be easily rolled into the enclosure through the strip curtain entrance. Both the process and surrounding environment are protected from contamination. A downward flow of HEPA (high-efficiency particulate absorbing) filtered air maintains a cleanliness level at drum or working height, while all exhaust air exits out through HEPA filters in the rear wall. — Hemco Corp., Independence, Mo.
