. . . a hot thick fire
and therefore speedy evaporation.
That’s the secret of boiler firing.

But you cannot get the best results
from the natural draught—that is,
chimney draught. A chimney relies
upon hot gases for its drawing power—
and that’s waste.

These hot gases should be utilised
in the reduction of your fuel bill.

The “Cyclone”

Induced Draught Plant

gets the maximum from the fuel. It
helps you to use cheaper fuel. And
it means—all the time—economy with
efficiency.

Write for our Booklet 275F to-day.
It will interest you.

Blower and Exhauster.

A few extracts from testimonials—facsimiles
of the original letters are shown in our Booklet.

“. . . the Induced Draught has given a satis-
factory result both in the Reduction of the Coal
Bill and the stopping of the Smoke Nuisance. .

“ . . . the use of the fan enables us to cope with
this load without having to put on extra boilers. .”

“ The savings to be effected by the plant above
referred to, will in 12 months time more than pay
for the Induced Draught Installation.”

“ Your fan has now been running 18 months.
We now use only the one Boiler, have reduced the
quality of coal 25Q/O . . . and have ceased to
receive notices from the Authorities re ‘ emitting
dense smoke.1 ”
