7.6 Changing the gas ballast filter
The gas ballast filter is soiled if the vacuum pump takes in ambient air containing dust during gas ballast
operation.
As the soiling increases, the throughput of the gas ballast filter decreases. The risk of condensation and
corrosion in the vacuum pump increases.
Required consumable material
● Compressed air
● Gas ballast filter
