Active-Carbon-Adsorber
Economic oil-free compressed air with activated carbon adsorbers
complete solution with oil-free dust filter low operating costs for residual oil content of max. 0.003 mg/m³
Compression-moulded activated carbon pellets for high compressed air quality
In order to ensure high compressed air quality with compressed air class 1-2 in accordance with ISO 8573-1, in particular with regard to the residual oil content, the CLEARPOINT V activated-carbon adsorber is the effective and reliable technical component in demanding system designs.
The consistent overall concept guarantees compressed air quality with a minimum residual oil content extremely cost-efficiently. Oil vapours and odours are adsorbed on the unusually large active surface of the compression-moulded activated carbon pellets. When selecting our activated carbon, we work together with selected suppliers who guarantee consistent carbon quality. A major advantage for your compressed air quality and process reliability.
How does compressed air become oil-contaminated?
Particles, oil aerosols, germs and moisture can enter the compressed air system in many ways – often already via the ambient air drawn in by the compressor. Nearby roads, industrial plants or construction sites increase the risk of contamination. High ambient humidity also raises the moisture content in the compressed air.
This contamination poses a double risk: it accelerates wear and malfunctions in the compressed air system and at the same time jeopardises product quality – and ultimately consumer safety.

Facts - Good to know
For the production of compressed air of ISO 8573 quality class 1, most operators use activated-carbon adsorbers that remove oil molecules from the compressed air by means of adsorption. As activated carbon also adsorbs water vapour, it can be quickly spent, especially where the air contains quite a lot of water vapour. At this point, the activated-carbon adsorber is no longer able to take up oil molecules, so that the concentration in the downstream compressed air exceeds the limit for quality class 1 (> 0.01 mg/m³). For long service lives and consistent low residual oil contents, the compressed air must therefore be dried before it enters the activated carbon.
Activated Carbon Adsorbers – Frequently Asked Questions
When is an activated carbon adsorber NOT sufficient?
An activated carbon adsorber such as CLEARPOINT V is ideal for defined residual oil vapour loads under controlled operating conditions.
However, if:
- oil vapour concentrations fluctuate heavily,
- unknown hydrocarbon loads occur,
- or absolute oil-free air must be guaranteed permanently,
a catalytic system such as BEKOKAT may be the more reliable long-term solution.
How can I calculate the service life of activated carbon in my application?
Service life depends on:
- inlet oil vapour concentration
- pressure and temperature
- residual moisture content
- operating hours
As a rule of thumb: the drier the compressed air and the lower the oil load, the longer the service life. A technical evaluation of operating parameters is recommended for precise sizing.
What happens if the residual oil limit of ISO 8573-1 Class 1 is exceeded?
Exceeding the limit defined in ISO 8573-1 (> 0.01 mg/m³ for total oil in Class 1) can lead to:
- Product contamination
- Audit non-conformities
- Production downtime
- Liability risks in sensitive industries
Continuous monitoring or periodic measurement is therefore recommended in critical applications.
Does an activated carbon adsorber remove oil aerosols as well?
No. Oil aerosols must be removed by high-efficiency coalescing filters upstream.
Activated carbon primarily removes oil vapours and odours, which pass through conventional filters.
Proper pre-filtration is essential for reliable performance.
Where should the activated carbon adsorber be installed in the compressed air system?
Best practice installation:
- After compression
- After drying
- After fine and micro filtration
- Before sensitive consumers
This ensures low moisture load and maximises adsorption efficiency.
How can I detect oil breakthrough early?
Possible indicators:
- Rising total oil measurement values
- Odour in compressed air
- Shortened cartridge lifetime
- Increased pressure drop
In critical processes, inline monitoring of residual oil content is recommended.
Is there a fire risk with activated carbon adsorbers?
Under standard operating conditions, activated carbon is safe.
For applications with elevated fire protection requirements, special versions (VH) with combustion-resistant carbon are available.
