                 SILVER SERIES II MEMBRANE
                 FINE BUBBLE DISC DIFFUSER




          Sanitaire presents the new Silver Series II membrane diffuser,
          the latest advancement in diffused aeration technology. This
          new disc diffuser element was designed through Sanitaire’s
          continued research and development of new technologies
   ALL    and represents the commitment Sanitaire has as the
          recognized technological leader in diffused aeration.
          Through independent testing and development, factors of
 THINGS   the various formulations and configurations of the
          membrane which affect the product’s performance and

ARE NOT   longevity were evaluated and monitored.

          The diverse applications of SANITAIRE aeration equipment

CREATED   have provided the unique opportunity to analyze membrane
          diffuser interaction with different environments, especially
          those known to be aggressive toward membrane materials.
 EQUAL    Installations include municipal, pulp and paper, textile, food
          and dairy and petrochemical. By studying these
          environments, extensive data and knowledge were gained
          regarding how membrane diffusers age with time in service.
          This information allowed Sanitaire to determine which
          characteristics provide useful membrane performance
          information.

          The Silver Series II membrane offers an extended operational
          life and achieves higher oxygen transfer efficiency than
          standard SANITAIRE diffusers. Testing has found power
          consumption to be reduced by as much as 10% with Silver
          Series II membranes.
