Control Air

Compressed air as control air plays a major role in commercial production and cannot, to date, be disregarded. There are numerous pneumatic applications and every one of them must be controlled.  

When compressed air is utilised to control cylinders, actuators or valves is used, then one refers to it as control air. Control air is mainly utilised because high working speeds are achieved, as well as enabling precise and exact controlling. Pneumatic control systems are also insensitive to environmental influences and can be utilised safely in potentially explosive areas. Control air can be utilised for simple compressed air tools as well as for robots with pneumatic components. In addition, it will also be utilised for the new generation of robots, the so-called Cobots (Collaborative robots).

The demands on the quality of the control air are not particularly high, since these do not usually have any direct contact with the product. This does not however mean that the compressed air does not have to be treated or processed. If the compressed air has insufficient quality, then it can accelerate the wear.  

In certain cases the quality requirements can also be higher - e.g. in a clean room or when the process specifies it. Consultation and individual design for compressed air processing and treatment is therefore important here, we will be very pleased to support you with this.


Application Reports


Compressed air production in the corrugated board factory

The company Delkeskamp uses compressed air as control air to specifically shape corrugated card boards, but also as process air to blow moldings out of the machines. Therefore Absolute dryness is particularly important so that the cardboard does not soften due to moisture.


Control and conveying air in food processing

In order to meet the extremely high demands placed on compressed air in the food industry, Nölke in Versmold uses our METPOINT OCV to monitor its compressed air quality. At Nölke compressed air is used in the sausage production as control and conveying air.


Compressed air as transport and operating medium

At GF Automotive, sand is transported by means of conveying air. Moisture would cause clumping in the pipes. Also control valves are operated with compressed air as control air. A DRYPOINT RA refrigerant dryer from BEKO TECHNOLOGIES ensures their dry air.

Compressed air treatment on hybrid locomotives

Control air is needed in the hybrid version of the ALSTOM shunting locomotive built in Stendal in order to supply the brake system with purificated compressed air. For this application, DRYPOINT M membrane dryers and CLEARPOINT filters are used.
