Removing and cleaning the filter silencer

If provided

u Remove filter ring(81265).

u Rinse the filter ring(81265) using water with detergent additive or, if

it is heavily contaminated, soak and carefully push through. Rinse in

cold water. Avoid high mechanical stress (do not use a water jet).

NOTICE

The amount of filter ring(81265) contamination depends on the cleanli-

ness of the air that is drawn in. Clean filter ring after every 500 hours of

service or more frequently if necessary.

them along with the cover grids (81266) and connecting strips

then take out absorption segments(81136).

During cleaning, ensure that the absorption segments (81136) are

only cleaned with a mild jet of compressed air, soft brush or a damp

cloth. Otherwise there is a risk of damage or deformation.

NOTICE

damaged connecting strips with original parts from ABB Turbo Sys-

tems.
