For Cooling Turbo-Generators and
supplying clean air to Compressors.

Thorough Washing.

The air current is brought into intimate contact with
a very fine mist, and all particles of foreign matter
are removed either in the spray chamber or by means
of the scrubber plates.

Elimination of Free Moisture.

A series of carefully - designed eliminator plates
removes all free moisture from the air current, which
passes out of the Washer in a cool and pure state.

Economy in Water.

The water is recirculated, passing on its way to the
spray nozzles through two sets of Filters.
