Over time, however, it loses capacity.
Measure the actual capacity and compare it with the nominal capacity
(see condensation door).
Replace in case of major deviations
Clean surface with compressed air
The pump must be cleaned regularly. The interval depends on the degree
of contamination on the casing.
Safety goggles and an FFP2 mask according to EN 149:2008 must be
