➤ The machine is delivered without a gas inlet filter.
The inlet gas must be:
■ clean
■ dry
■ pure
■ chemically inert
■ free of solid particles larger than 3 — 4 µm
■ incombustible
■ non-toxic
➤ The pressure dew point that will not be exceeded during compression.
➤ The user must install a fine filtration system in the gas feed line to exclude solid particles
including welding beads, dust and attrition from pipework and valves.
Filter porosity: ≤10 µm at 100 % efficiency
➤ The pressure loss of the intake filter may not exceed 0.05 bar.
If this value is exceeded due to excessive filter contamination, a pressure differential
monitoring installed by the user shall trigger an alarm or switch off the machine in time
before the system falls below permissible intake pressure.
Oil return line
The compressor oil fed to the helium compressor from an external source must have a minimum
fineness of 100% for solids ≥39 µm according to ISO standard 4548/12.
➤ If necessary, a suitable oil fine filter must be installed by the user.
Chapter 13.1 provides more information about the connection of the oil scavenge line to the
user's oil fine filter.
