HEMCO “CCS” Controlled Containment System enclosures safely contain and control airborne particulate to and 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. A downward flow of HEPA-filtered air maintains a cleanliness level at drum or working height while all exhaust air exits out through HEPA filters in the rear wall at floor level. The interior is under slight negative pressure to ensure that no contaminant escapes out of the enclosure. LEARN MORE
