ACT Series - Activated Carbon Adsorbers - 1.17 to 154.5 m³/min

Best air quality for continuous operation

HPC KAESER ACT Series Activated Carbon Adsorbers 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 enduring low pressure loss make the ACtT Series a highly cost-effective choice: the units can provide 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.
