Customer manufactures synthetic fabrics.  They use a hot knife to cut the web to length, to melt the ends of the fabric to prevent fraying and unraveling.  This melting creates quite an offensive, yet non-toxic odor.  The cut and melt area is fairly small, so a large ventilation system is not required.  A Model 120020 3/4" (19mm) Super Air Amplifier will provide 90 scfm of total airflow, more than enough to sufficiently remove the odorous air from the area.
