Use of air as a medium in rotating unions:
In mechanical engineering
- CNC machines: Supply of pneumatic clamping systems that hold workpieces in place during processing.
- Machining centers: Control of tool changes or rotating grippers
In the packaging industry
- Rotary conveyors: Supply of rotating elements in packaging lines, e.g. in bottling plants.
- Labeling machines: Operation of rotating modules that use compressed air and vacuum for grippers or suction cups.
In the automotive industry
- Assembly robots: supplying end effectors (e.g. grippers or screwdrivers) on rotating robot arms with compressed air.
- Tire mounting machines: Checking collets or rotating brackets.
In the printing industry
- Printing machines: Transfer of compressed air or vacuum to rotating cylinders to hold, move or stabilize sheets of paper.
In the conveyor technology
- Turntables and carousel systems: Supply of pneumatic actuators in rotating conveyor systems with compressed air and/or vacuum.
In the energy technology
- Wind turbines: Use in systems that use air to control the pitch of the blades (pitch control).
In the food industry
- Rotating filling systems: Used for bottle filling systems in which pneumatic components operate in rotating modules.

Advantages of rotating unions for use with air
Reliability and durability
Robust materials and precise construction ensure long-lasting operation, even under demanding conditions (high speeds, pressures or temperatures).
Flexibility in the application
Suitable for different speeds and pressure ranges. Can be adapted to the specific requirements of machines, e.g. number of air ducts (paths) or medium.
Low maintenance
High-quality rotating unions require minimal maintenance thanks to low-wear bearings and durable seals.
Space-saving design
Compact designs facilitate integration into machines with limited installation space. (can also be adapted to customer requirements)
Safe and clean
Compressed air is an environmentally friendly and safe medium compared to oil or water-based alternatives. This is particularly important in hygiene-critical sectors such as the food and pharmaceutical industries.
Versatility
Can be adapted for various applications, from simple compressed air supply to the control of complex pneumatic systems.
Adaptability for multi-channel systems
Rotating unions can be designed in such a way that several air flows (or media flows both liquid and gaseous) can be operated in parallel in different ducts (e.g. for control air and drive air).
Cost efficiency
Reduced energy loss and low maintenance costs lead to long-term cost savings.
