There are two types of shaft seals that have been
used interchangeably in the Vilter VSS and VSR
Single Screw Compressors. The first type has a
stationary mirror face and rotating carbon. The
second type has a stationary carbon and a rotat-

in the compressors. On Vilter VSM compressors
the type of seal utilized has a stationary carbon
and a rotating mirror face.
