Ductless Downflow Workstations

DWS™ Downflow Workstations are high efficiency ductless fume hoods designed to protect the user and the environment from hazardous vapors generated on the work surface. Unrestricted front and side access to the ductless workstation facilitates applications requiring complex and intensive operator involvement, while downward airflow in the chamber protects the operator.

A. Filter I.D. Window: A strategically placed front cover window shows the installed filter part number and installation date for convenience and to encourage timely filter replacement.

B. Control Panel: Electronic controls and displays include switches for the blower, filter blockage alarm and electronic hour counter.

C. Filter Blockage Alarm: Continuously monitors filter loading and alerts user when service is needed.

D. Steel Support Frame: The chemical resistant epoxy coated steel frame adds mechanical strength. Optional all polypropylene construction is available if desired; see accessories.

E. Work Surface: Under the perforated stainless steel internal work surface is a polypropylene tray to retain any spillage.

F. Rear Shelf: Epoxy-coated steel rear perforated shelf provides additional storage space for operator tools and analysis materials.

G. Electrostatic Pre-Filter: The electrostatic pre-filter is accessible from inside the chamber and 91% effective down to 1-3 microns.

H. Filter Door Key: Filter access keys prevent unauthorized removal or accidental exposure to dirty filters.

I. Internal Manual Speed Controller: The operator may set the centrifugal fan motor speed as desired.

J. Internal LED Lighting: A vapor proof LED lamp illuminates the interior of the workstation.
