Activated Carbon Absorber

Kaeser ACT-series activated carbon filters reliably remove oil vapours and odours. Installed downstream of compressed air drying and pre-filtration components, they attain Class 1 residual oil content as per ISO 8573-1, thereby protecting sensitive production processes. Generous fill levels of high-quality activated carbon and their enduring low pressure loss make them a highly cost-effective choice: they can last 12,000 hours of compressor operation without replacement of the activated carbon. An oil indicator fitted as standard indicates any operational disruptions.


  • Residual oil content within the concentration range: 0 - 0.01 mg/m³
  • Flow rate: 1.17 - 154.5 m³/min
  • Max. working pressure: 10 bar / 16 bar and optionally, 48 bar


  • Significantly lower values than required by Class 1: Class 1 as per ISO 8573-1 is achieved with residual oil content as high as 0.01 mg/m³, yet Kaeser ACT desiccant dryers can deliver significantly lower residual oil content. This means consistently reliable compliance with limit values.
  • Low maintenance costs: Kaeser ACT adsorbers have very long replacement intervals thanks to their generous dimensions and optimal flow dynamics through the highly effective activated carbon. They're also mounted in a protective and durable steel frame.
  • Minimal pressure loss: Generously dimensioned inlet and outlet diameters ensure consistently low differential pressure, thereby enhancing cost-effectiveness.
