Economic oil-free compressed air with activated carbon adsorbers

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.

Depending on the compressed air volume required, BEKO TECHNOLOGIES can offer you the suitable solutions.

By connecting several activated carbon adsorbers in parallel, respective higher volume flows can be processed.

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.

Our measuring technology especially for oil vapour measurement

Compressed air contaminated with oil can cause damage to production equipment, the environment and even health. Since contamination with oil can occur at every stage of compressed air treatment, the risk must not be underestimated particularly in sensitive production areas in the chemical and pharmaceutical industry, food and beverage production facilities and surface finishing.

Using the suitable measuring technology, you can monitor whether the defined limit values are reliably observed. The METPOINT OCV compact continuously analyses the oil vapour content of your compressed air and triggers an alarm in the event of deviations. In contrast, the analogue oil test indicator makes periodic measurement directly at the respective treatment component possible.


The METPOINT OCV compact (Oil Content Vapour) makes continual online monitoring and documentation of the residual oil vapour content possible. The measuring section is located directly at the compressed air outlet of the activated-carbon adsorber. Thus the METPOINT OCV compact makes an important contribution towards boosting the process safety of your system.

Enhanced safety through oil test indicator

An adapter with an oil test indicator and pressure gauge can be mounted on the head of the filter housing in order to determine the compressed air quality. When the needle valve is completely opened, a defined volume flow flows through the testing tube. The oil contained in the compressed air results in a progressively red discolouration of the testing tube from bottom to top.

The oil testing tube is used for period measurement of the residual oil content downstream from a treatment component in a compressed gas system or at a point in the compressed gas network. Multiple measurements are possible until the load limit has been reached.

Applications with oil-free compressed air

Sichere ölfreie Druckluft für die Pharmaproduktion

Safe oil-free compressed air for pharmaceutical production

For the production of medicaments, the strictest hygienic standards apply to the production conditions. This of course also applies to the required compressed air. It must be absolutely free from oil in order not to contaminate the sensitive products. In its factory in Singen, Germany, drug manufacturer Nycomed relies on a comprehensive system solution provided by BEKO to treat the process air in a reliably oil-free manner.

Druckluftaufbereitung in der Getränkeindustrie

Compressed air treatment in the beverage industry

Every hour, 150 cubic meters of purest mineral water are produced by the 14 wells of RheinfelsQuellen in Duisburg-Walsum. Enough to fill 883 bathtubs every 60 minutes – or more than 207,000 bottles. To add sparkle to the water, there is only one solution: oil-free compressed air fed to state-of-the art bottling plants and peripheral systems. The company uses an innovative catalytic process for the total oxidation of hydrocarbons in the compressed air system.
