 ACT series

Continuous operation, maximum compressed

air quality
Kaeser ACT series activated carbon adsorbers are true masters when it comes to delivering a continuous supply of premi-
um quality compressed air that is technically oil-free and which is both 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 to ensure
dependable protection of sensitive production processes.

They are therefore the perfect choice for applications in the optical, surface technology, electronics, foodstuffs and pharma-
ceutical sectors.

Technically oil-free compressed air Energy savings

In order to meet the strictest Class 1 compressed air purity Generously-dimensioned flow diameters, together with
class requirements as stipulated by industrial standard stainless steel flow diffusers, ensure even flow distribution
ISO 8573-1, compressed air should have a residual oil with an exceptionally low pressure loss no higher than
content no higher than 0.01 mg/m³. Class 1 compressed 0.1 bar. As a result, the compressor discharge pressure
air is therefore significantly cleaner than typical ambient of upstream compressors, as well as the energy costs for
air. For this reason, compressed air treatment is essential compressed air production, can be kept as low as possi-
irrespective of the compression method that is used to ble.
produce it.

In order to achieve this level of purity, more is needed than

purity. nance, the carbon used is abrasion-resistant, low-dust and
has minimal ash content.

Furthermore, specially designed stainless steel flow diffus-

ers ensure even flow distribution throughout the activated
carbon bed. Consequently, the exceptional compressed air
purity is reliably assured for up to 12,000 full load hours, or
a maximum of five years.

Low life-cycle costs

Kaeser ACT activated carbon adsorbers are hands-down
winners from a cost perspective compared to typical
activated carbon filters. Thanks to significantly longer
service intervals, their life-cycle costs in the third year Image:

alternative. This advantage is further bolstered by better
compressed air availability resulting from the lower number
of necessary service visits.
