Ductless Downflow Workstation DWS24

The Air Science Purair 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 facilitates applications requiring complex and intensive operator involvement, while downward airflow in the chamber protects the operator.

The Eco-Friendly Choice

Advanced carbon filtration technology offers a safe, high performance  alternative to conventional ducted fume hoods for a broad range  of applications.

Environmental Benefits -  Air Science ductless fume hoods isolate and  trap chemical vapors to prevent ecological impact through release into  the environment. 

Versatile -  Each filtration system is selected for its specific application.  Carbon filters are available in more than 14 configurations for use with  vapors of organic solvents, acids, mercury and formaldehyde.  HEPA/ULPA filters can be added for biological safety. 

Easy to Install - The ductless fume hood is self-contained and does not  require venting to the outside. Many units are portable and may be moved  with minimal downtime and without filter changes. Set-up, operation  and filter maintenance are straightforward. 

Energy Efficient -  Because filtered air is returned to the room, no  demands are required of the facility HVAC capacity for make-up air. 

Cost Effective  - Facility ductwork, HVAC and construction costs are eliminated. 

Safe to Use - Cabinet airflow and face velocity protect users from incidental  exposures to fumes. 

Self-Testing - (select models) Electronic airflow monitoring assures continuous  safety. An electronic gas sensor monitors carbon filter performance.
