• Compressed air is produced locally by compressing atmospheric air, drying it, and filtering it for particles.
• Purity according to ISO : 8573 class 2, meaning: dew point of -40 degrees and a purity of 0.003 Micron
• Pressure in the pipes is 7.0 bar.
• The compressed air is not filtered chemically, thus its content of NO_x and CO₂ will be the same as the air outside the building.

• Compressed air is used for drying, clean blowing, and for instruments.

• Compressed air is often used directly.
• If you want to regulate flow and pressure, you have to connect a needle valve and a pressure regulator.

• Compressed air has the same content of oxygen, nitrogen, and argon. Thus, it is not suited as inert atmosphere.
• The pressure is high enough to be able to blow up closed glass flasks.
