Negative air flow containment is necessary in laboratories and other environments where personnel can be exposed to potentially hazardous powders or air particulates.
CleanZones manufactures HEPA Negative Flow Exhaust Work stations in two configurations to meet your negative flow room requirements. Commonly used as filtered workstations or powder weighing stations in the following industries:
HEPA Filtered Workstation units in the Negative Flow Exhausting (NFE) Series are designed for fine powder sampling and weighing. These filtered workstations provide containment of contaminated air through intake at work chamber. This unit is designed with a three-stage filtration process of powders to protect the operator. Air is initially drawn into the work chamber and through 2” MERV 7 high capacity pleated prefilters to collect gross contaminants. The second stage of filtration is with 95% efficient HEPA filters. The air is then passed through an exhaust HEPA filter for removal of any remaining particulates. Use of this exhaust filtration eliminates the need to duct to the outside. The unit is designed with full leg room below the standard 24” deep tabletop. Completely self-contained, it functions effectively in an uncontrolled area. Special custom products are available without the custom cost for application specific projects.
The Containment Weigh Station (CWS) Series units are designed for fine powder weighing. The CWS Series provides containment of contaminated air through intake at work chamber. The confined work chamber prevents airborne dust/powder from escaping into a plant’s atmosphere or the cross-contamination of other products. Dual sliding shields adjust to any desired height for exacting sampling and weighing processes. The initial disposable bag filter collects gross contaminants, and then the air passes through exhaust HEPA filters. The CWS series allows for extremely low intake velocities, protecting the accuracy of highly sensitive scales or measuring devices.
