All of the surfaces on the diffuser must be free of contamination after cleaning. In the
u
case of slotted diffusers, this applies in particular to the diffuser slots (03) and the dif-
fuser annulus (02).
Cleaning procedures should be selected that do not result in removal of the diffuser's
u
base material or damage to its surfaces.
The evenness of all surfaces (01) between the diffuser blades must be checked visually.
u
The surfaces must be flat and even. Any deformations or deteriorations of the surface
caused by the cleaning process are not permitted.
Have damaged diffusers replaced by a Turbo Systems service station.
