Maintenance frequency and service lives
Maintenance frequency and service lives are process-dependent. Chemical and thermic
loads or contamination reduce the recommended reference values.
● Determine the specific service lives during the first operating interval.
● Consult with Pfeiffer Vacuum Service if you wish to reduce the maintenance frequency.
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.
