rJnHE “SIROCCO” FAN
proved from the very start
to be highly efficient under
various and severe operating
conditions. Subsequent changes
have increased its efficiency and
durability, reducing the cost of
maintenance and operation to
a minimum. This development
has resulted in an improved,
but not a new, “ Sirocco.”
The increased efficiency is the
result of mechanical refine-
ments of construction, which
have left unchanged the
essentials of the original design.
