Tools and accessories
Hoses for feeding and discharging the purge air, suitable for M3-PK-2 plug nipple
Suitable purge air:
The requirements on purge air quality can generally be met by running compressed air
conformant to ISO 8573-1:2010.
Particulates: Class 2
Humidity: Class 4 (Temperature at least 3 °C above dew point)
Residual oil content: Class 1 (<0.01 mg/m³, measured at 1 bar and 20 °C)
The pressure in the purge air supply should be between 0.5 bar and 1 bar.
Connecting the purge air
1.
