Series 2<br />
PADDLE WHEEL<br />
Series 2 fans were originally developed for use on textile-type motors, but many<br />
manufacturers use these “paddle-wheel” shapes for both internal and external<br />
motor cooling. The absence of a back plate on these fans permit airflow through the<br />
motor in either direction. These fans are particularly adaptable since it is so easy to<br />
shorten the blades to reduce the overall diameter or to shape the blade tips. All fans<br />
of this type work by creating a higher-pressure at the blade tips. The shape of the<br />
fan cover or motor housing then determines the path of the higher-pressure air. The<br />
pressure is typically a few pounds per square foot near the blade tips and varies<br />
with the motor speed.<br />
