ABSTRACT:
The present invention provides a method and conversion kits, that include all necessary components, to convert any style existing prior art fume hood into a stable vortex high performance low airflow fume hood that can accommodate varying size prior art fume hoods without altering the fume hood envelope or customizing the conversion kit. The articulating rear baffle can be lifted out for cleaning debris that collects in baffle conduit. The conversion can be accomplished without drilling mounting holes into an asbestos liner and can be applied on any size or style prior art fume hood. The present invention also provides a new fume hood incorporating the features of the method and kit.
