Progroup’s new PM3 paper mill plant is reinventing paper technology, showing the world that high production can be achieved through sustainable and environmentally friendly means. However, even this innovative facility which only uses recycled goods for production, emits corrosive gases as manufacturing byproducts, which over time could cause damage to the new equipment that the plant is utilizing.PureAir was reccommended to Progroup and it’s contractor by Finnish engineering company, Poyry 
(AFRY), which handled the HVAC design for the site and confirmed the need for gas-phase filtration systems to remove the harmful hydrogen sulfide (H2S), sulfur 
dioxide (SO2), and sulfite (SO3), and other corrosive gases that were found in the air through Progroup test reports, ensuring critical electronics are protected. Even trace amounts of corrosive gases could cause irreversible damage to critical hardware and data systems over time.
