Compressed air preparation unit
Bosch Rexroth
supply compressed air with a pressure of 30 bar.
Pressure reducing stations
reduce that pressure to 6-8 bar.
Filters with integrated drain valve
hold back impurities,
drain the air:
Atmospheric air always contains a certain amount of water vapor. After leaving the compressor, compressed air is 100 % saturated. Water will be released if the air cools down further within the following piping system. Regular drainage is essential to prepare the control air suitably.
should be installed before the pressure station.
Air dryers
are necessary in case the normal drainage is not sufficient,
operate according to the "cold regenerated adsorption drying"- method.
Antifreezers
have to be used if the pneumatic control is exposed to temperatures below + 5°C.
