Carbon Absorber

Best air quality for continuous operation

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

Technically oil-free compressed air

In order to meet the strictest Class 1 compressed air purity class requirements as stipulated by industrial standard ISO 8573-1, compressed air should have a residual oil content no higher than 0.01 mg/m³. Class 1 compressed air is therefore significantly cleaner than typical ambient air. For this reason, compressed air treatment is essential irrespective of the compression method that is used to produce it. In order to achieve this level of purity, more is needed than to simply remove the residual fluid oil content via filters. The vapour component also needs to be retained by means of adsorption on activated carbon. High performance ACT series activated carbon adsorbers from Kaeser can achieve residual oil content significantly lower than the threshold value for Class 1 compressed air purity.

Your advantages

• 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.
