In 2005, a 7100 CFM Bioclimatic air-handling unit was installed to treat exhaust air from the manufacturing section of the building. It contained a filtration section (for removal of dust particles from the plastics processing) and a single stage of a specific gas phase media (selected for removal of fluoropolymer resin effluents including hydrofluoric acid). In 2018, the new 4000 CFM system was installed. This was designed to adsorb butyraldehyde, benzaldehyde and other VOCs prior to exhausting the air to atmosphere.
