DUSTSHIELD filters work hard to protect computer equipment from the airborne contaminants in your production environment. The Positive Pressure Environment inside DUSTSHIELD enclosures depends on a sustained flow across the fans to force only clean air out of the enclosure's exhaust and cable ports. With continuous flow, contaminants are prevented from entering the enclosure. DS612 replacement filters provide activated carbon/activated carbon filtration for environments with especially oily air, exhaust vapor, and fumes.
