Pneumatic
Pneumatic means that something is driven or controlled by air or gas under pressure. The term is mainly used in industry, where compressed air is used as an energy source to create movement or control. Pneumatics - the technical term for the technology behind it - is an important part of many automated systems, ensuring fast, precise and clean movements.
What is pneumatic technology?
Pneumatic technology is about using compressed air to transfer force. This is done through a system that typically consists of:
- A compressor that generates compressed air
- A network of pipes and hoses that carry the air
- Valves and actuators that control and convert pressure into movement
In practice, compressed air is used to push, pull, open, close or rotate components. This can be anything from valves and cylinders to automatic machine parts in production lines. Pneumatics is an alternative to electrical and hydraulic solutions and is often chosen when reliable, clean and safe movements are needed.
Advantages and disadvantages of pneumatics
Pneumatic equipment is widely used - and for good reason. The technology has several advantages:
Benefits:
- Fast response and precise movement
- Low weight of components
- Reliability in demanding environments
- Low risk of leaks (no oil or electricity)
- Safety - works at lower pressure than hydraulics
Disadvantages:
- Requires a constant supply of compressed air
- Lower power output compared to hydraulics
- Can be energy-intensive with leaks
- Depends on good maintenance and air quality
A well-functioning pneumatic system therefore requires both proper design and continuous monitoring of air pressure and tightness.
How to use pneumatic equipment
Pneumatics is a cornerstone of many industrial automation systems. Among other things, it is used for:
- Opening and closing valves
- Movement of cylinders and gripper arms
- Conveyor and packaging machine control
- Positioning and dosing in production lines
The technology is particularly suitable in environments where electrical solutions are less appropriate - for example due to explosion risk, moisture or high hygiene requirements.
Typical industries include:
- Food production
- Pharmaceutical industry
- Cosmetics and care products
- Biotechnology
- Packaging and filling lines
Pneumatic equipment is also popular in cleanrooms and wet rooms where it must not dust, sparkle or leak liquids.

Pneumatic equipment FAQ
How does a pneumatic valve work?
A pneumatic valve controls the movement of air in a system. It regulates whether air flows through, in which direction and with what force - and typically activates cylinders or actuators.
What is a pneumatic push button?
A pneumatic pushbutton is a manual component that releases compressed air under pressure. It is often used in potentially explosive environments where electricity must not be used.
What do pneumatic tyres mean?
Pneumatic tyres are air-filled tyres used for shock absorption and comfort - for example on bikes, cars and trolleys.
What is pneumatics used for?
Pneumatics is used to control and drive moving parts in machines and plants - especially where fast, safe and hygienic solutions are needed.
