FUME HOOD TESTING AND SAFETY ISSUES

AS A REFERENCE POINT, HERE ARE SOME GRAPHS SHOWING THE PERFORMANCE OF
THE VORTEX II BI-STABLE VORTEX FUME HOOD

When tested to the standards of the ASHRAE 110-1995 Method of Testing Laboratory Fume Hoods,
the Vortex II, Bi-Stable Vortex Fume Safety Cabinet performs exceptionally well.
It qualifies as a "Class A" fume hood, per the performance specification in the ANSI/AIHA Z9.5-1992 American National Standard for Laboratory Ventilation.

PLEASE NOTE THAT THE CHANGE IN SASH POSITION
DOES NOT AFFECT THE PERFORMACE OF THE VORTEX II

These ASHRAE tracer gas test results show a standard 6' bench Bi-Stable Vortex Fume Safety Cabinet's performance, in both the horizontal and vertical sash postitions at 59 FPM and 44 FPM respectively indicating a spillage rate well below the acceptable criteria of 0.05 ppm of tracer gas. Testing was completed by an independent testing agency.
