There are a few ways to determine if the filter cloth on a vacuum filter is blinded and needs replacement. If the cake is not uniform, or is thick in sections but thin or non-existent in other sections, it may be blinded. Similarly, if the filter cloth will not form a consistent filter cake it may be blinded.
A cloth may also be blinded if pressure washing of the filter cloth does not regenerate its permeability. Visually impaired filter cloth with small holes or a filmy appearance also indicates the cloth is blinded.
