CENTRIFUGAL FAN

I he Fan for Hard Work

The Original

Many-Bladed Fan.

There is no guesswork about the “ Sirocco.”
Careful study of Fan design and experience
gained in the manufacture and application of
thousands of Fans have eliminated all elements
of doubt. We know exactly the capabilities
of each size, and how to apply it to ensure
absolute reliability and high efficiency. That
is why the “Sirocco” Fan will work all day
and every day without risk of breakdown.
