Vertical Bed System (VBS)
PureAir Filtration’s Vertical Bed System (VBS) system is a complete self contained, vertical airflow unit.
This deep bed system provides continuous high efficiency air purification for contaminated air streams ranging in volume from 150 to 8,000 CFM. Because the system has a vertical airflow, the potential for air bypass is completely eliminated. The PureAir VBS systems come in either blow-through or draw-through configurations.

One of the byproducts of paper production is hydrogen sulfide, and in recent years, as EPA regulations tightened and more research became available on the effects of hydrogen sulfide (H2S), complaints and questions began to surface regarding the malodorous and corrosive air quality.
Leaders at Georgia Pacific deemed it necessary to reduce H2S levels and have made strides in doing so in recent years.
Wanting to stay away from high maintenance units, like chemical or wet scrubbers, PureAir recommended using a Dual Train VBS-720 system and Sulphasorb FeXL™ and Sulphasorb XL™ adsorbent media. The VBS-720 is a limited maintenance system designed to manage a high volume of airflow with a considerable saturation of H2S.
Due to the especially large odor volume, our custom engineered units and superior performing media saved the plant considerable maintenance and costs.
