With minimum residual oil contents of less than 0.003 ppm, the DSS120A-DSS630A oil vapor activated carbon adsorbers are among the market leaders. As an extension or supplement, they are optimally matched to heatless regenerated FST adsorption dryers of the DPS120-DPS630 series. With appropriate pre-drying and pre-filtration, these cost-efficient active carbon adsorption systems achieve impressive service lives of over 8,000 hours.
