DualDraw Patented Technology
DualDraw holds two US patents related to air quality equipment. These patents set DualDraw apart in the marketplace for air quality equipment. Both focus on the design of the downdraft table work surface and its signature vented back stop.
The standard downdraft table work surface and vented back stop are perforated with hundreds of small perforations. Each perforation is spaced and sized uniformly from the next perforation. When air is drawn through these perforations, a vacuum is created and an even capture velocity is demonstrated across the downdraft table work surface and vented back stop.
This symmetrical airflow across the work surface and vented back stop creates a uniform protective airflow across the entire downdraft table work surface. Thus, trained operators performing an application on the downdraft table work surface can be assured that their breathing zone is protected and cross contamination to other areas of their facility will be minimized no matter where on the work surface their process is performed.
