Negative Flow Exhausting Work Station NFE Series

CleanZones’ Negative Flow Exhaust Workstations options
Negative Flow Exhausting Work Stations NFE Series :

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.

NOT TO BE USED FOR TOXIC FUME REMOVAL OR WITH ANY COMBUSTIBLE GAS.
Features

  • Standard construction is wood board with plastic laminate exterior. Corrosive resistant Polypropylene, Epoxy painted steel, 304 or 316L Stainless Steel units are also available.
  • Easily removed and replaced front loaded 2” MERV7 prefilters.
  • Front loaded igh Efficiency Particulate Air (HEPA) INTAKE Filter: 3” thick minipleat design 95% efficient @ 0.3 micron in an anodized aluminum frame, PSL tested in accordance with IEST Standards.
  • Front loaded High Efficiency Particulate Air (HEPA) EXHAUST Filter: 3” thick minipleat design 99.99% efficient @ 0.3 micron in an anodized aluminum frame, PSL tested in accordance with IEST Standards.
  • High Efficiency direct drive 120V motor blowers for continuous duty. Motors/Blowers are selected to maintain constant airflow rate up to twice the initial static pressure.
  • Solid-state speed control.
  • Recessed 2 pin T-8 fluorescent lighting 100 ft. candle on work surface and prismatic refractive lens cover.
  • Three-Prong 120V power cord.
  • Clear Acrylic Side Panels.
  • Individually tested and certified that Exhaust HEPA filters meet or exceed the specifications for Unidirectional Flow Clean-Air Devices as per Institute of Environmental Sciences and Technology recommended practices.

Containment Weigh Station CWS Series

Containment Weigh Station CWS Series :

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.

Completely self-contained, it functions effectively in an uncontrolled area. Special custom products are available without the custom cost for application specific projects.
