COMPRESSED AIR SUPPLY SYSTEM
GB
A good compressed air system must supply air that is free from impurities and condensation, lubricated if necessary and
at the correct pressure. Careful attention must therefore be paid to the connection of the pipes and hoses, which must
have dimensions compatible with the overall quantity of air required by each different user and the length of the pipes
themselves. Fig. 2 illustrates the general layout of a system set up correctly. Note that the inside dimensions of
connections and valves must not be smaller than those of the pipes and hoses in which they are inserted.
AIR PRESSURE
. The pressure of the compressed air supplied to the tool must be between 5.5 and 6.5 bars. Lower
pressure results in a loss of power, higher pressure may cause damage and in any case shorten the life of the tool.
QUANTITY OF AIR
. See table 1. The quantity indicated refers to non-stop operation. Intermittent operation carries lower
consumption levels (proportional to the time of use).
PIPES, HOSES AND CONNECTIONS
. See table 1: If the length exceeds 5 m, increase the diameter. Use oil-resistant
pipes and hoses. Use connections that do not obstruct the air flow, do not use damaged or worn piping. Inspect the
supply piping before use.
CLEANING THE AIR.
The air must be free from impurities (dust, condensation, dense oil, etc.). Always use a filter,
placing it as close as possible to the tool. Empty the filter daily.
LUBRICATION
. OBER tools
work with lubrication. Proper lubrication, guarantee by mist lubricators, enhances the
performance of the components and makes them last longer. Use only special oil for pneumatic tools (OBER code
5989902). We recommend using automatic lubricators. One or two drops of oil a day are sufficient.
