Notes on maintenance intervals
The times for the maintenance intervals depend to a great extent on the process condi-
tions; they apply for working with clean and inert gases. The use of corrosive process gas-
es can substantially curtail the maintenance intervals.
● Agree shorter maintenance intervals for extreme loads or for specific processes with
the Pfeiffer Vacuum
Maintenance intervals
You can carry out the inspection yourself.
We recommend Pfeiffer Vacuum Service for carrying out maintenance work of Mainte-
nance Level 1 and Maintenance Level 3 (revision). If the required intervals listed below
are exceeded, or if maintenance work is carried out improperly, no warranty or liability
claims are accepted on the part of Pfeiffer Vacuum. This also applies wherever parts other
than original spare parts are used.
