Kaeser ACT series activated carbon adsorbers

The ACT series activated carbon adsorbers from Kaeser are able to deliver a continuous supply of compressed air that is technically oil-free as well as odour- and taste-neutral. Installed downstream of compressed air drying and pre-filtration components, they attain Class 1 residual oil content as per ISO 8573-1, making them suitable for applications in the optical, surface technology, electronics, foodstuffs and pharmaceutical sectors.

In order to meet the ISO 8573-1 Class 1 compressed air purity class requirements, compressed air should have a residual oil content of 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.

The ACT series utilises a high-quality and generously sized activated carbon filling. Optimised for gas purification, this special type of activated carbon is fine-pored and possesses a high retention capacity. Specially designed stainless steel flow diffusers ensure even flow distribution throughout the activated carbon bed so that compressed air purity is assured for up to 12,000 full load hours, or a maximum of five years.

Generously dimensioned flow diameters, together with the stainless steel flow diffusers, ensure even flow distribution with a low pressure loss no higher than 0.1 bar. As a result, the compressor discharge pressure of upstream compressors, as well as the energy costs for compressed air production, can be kept as low as possible.
