SECTION OF SCREENING PLANT AT BENTLEY COLLIERY, DONCASTER.

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.

YEARS of STUDY
and EXPERIENCE
HAVE BROUGHT
MY SYSTEM OF
CEMENTATION
TO PERFECTION.

TO COLLIERY PROPRIETORS.

Shafts sunk, tunnels driven, and
other mining constructions carried
out in difficult and very wet ground
by the best method. Success guar-
anteed.

Ferro-Concrete Lining a speciality.

Feeders of water in shafts or levels
effectually treated.

The Rings are Flexible, they Expand
Automatically to Pressure, are Always
Tight, are not Split, do not cause Uneven
Wear, Reducing Friction to a Minimum.
