Joe, We just got finished designing a lab specifically for HF use, we went with the AirMax Polypropylene Fume Hood with Mistline Fume Scrubber. All ductwork downstream of the HF hood is fluoropolymer coated stainless steel, which is sufficient for a wet or dry HF exhaust stream. http://www.aircleansystems.com/totalexhaust_flame.htm The hood is due to be installed in mid December so I can't comment on it's actual performance yet. Price installed with a 25 foot duct run to/through the roof is about $45 K. Chuck Cooper Environmental Health and Safety Portland State University 503-725-4312 cooperc**At_Symbol_Here**pdx.edu
