Negative Flow Exhaust Work Stations

1.   Negative Flow Exhaust Work Station
2.   Containment Weigh Station

CleanZones, LLC offers our Negative Flow Exhaust Work Stations in two different design configurations and materials of construction to meet your exact requirements.  All of our Negative Flow Exhaust Work Stations feature HEPA or ULPA Fan Filter units, recessed lights, clear acrylic side panels to contain the airflow and adjustable solid state airflow control.

We offer two types of Negative Flow Exhaust Work Stations, Containment Weigh Station Cws Series.  Choose the correct type for your application or call and speak to our experienced sales engineer for assistance.

NEGATIVE FLOW EXHAUST WORK STATION NFE SERIES

We offer the NFE Series Negative Flow Exhausting HEPA Filtered Workstation units designed for fine powder sampling and weighing.  The NFE Series Negative Flow Exhausting HEPA Filtered Workstation provides 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 table top.  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 for all of our Negative Flow Exhausting Work Station

• 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.

Many options are available for this unit.  Consult our factory trained experienced sales engineering staff for more details

CONTAINMENT WEIGH STATION CWS SERIES

We offer the CWS Series Containment Weigh Station units designed for fine powder weighing.  The CWS Series Containment Weigh Station provides containment of contaminated air through intake at work chamber.  The confined work chamber prevents airborne dust/powder from escaping into the plant atmosphere or cross-contaminating other products.  The 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. NOT TO BE USED FOR TOXIC FUME REMOVAL OR WITH ANY COMBUSTIBLE GAS.
